CALIFORNIA, Los Angeles – May 16, 2011 – The global scientific community is eyeing suspiciously a 1952 ‘experimental projects’ organization known as the Conseil Européen pour la Recherche Nucléaire ( CERN ) [ ( also known as ) European Organization for Nuclear Research ] wherein its Large Hadron Collider ( LHC ) consists of a huge 27-mile in diameter high-energy particle collider is conducting some extremely serious experiments involving what scientists and physicisys say involves something called a “CP-violation” that deals with creating a variety of new subatomic particles that are believed to have never existed anywhere on Earth.

There is quite a bit of controversy concerning something called a “strangelet” ( strangelets ) and other particle creations within the CERN experiment, which because of conjectures in scientific theories are feared by some professionals, could create a ’new subatomic particle’ that may upset the balance of Earth as we know it, and what is even more frightening is that if something goes out-of-control, it may take anywhere between 1-year to 5-years ‘before anyone notices a chain reaction having already been created that some have already identified as a ‘micro-blackhole’ that could theoretically begin consuming Earth from within its own magnetic iron core. Sounding like ‘science fiction’, apparently CERN experiments are ’definitely not’ something to be taken lightly.

This serious and highly controversial subject amongst scientists and physicists around the world is being touched-on in this report, amongst other related information, amongst which includes video clips ( below ) for better understanding some of the many aspects for public knowledge not being addressed by mainstream news broadcasts.

CERN went even further, though, by expanding its deep underground experiments to conduct related experiments in outerspace within what it calls the Alpha Magnetic Spectrometer ( AMS / AMS-02 ) now scheduled for launch aboard the U.S. Space Shuttle Endeavor STS-134 mission set for May 16, 2011. The AMS-02 is, however, to be delivered to the International Space Station ( ISS ) where it will continue CERN designated experiments.

Interestingly, during July 2010 the Alpha Magnetic Spectrometer ( AMS / AMS02 ) was ‘not’ launched as the video clip ( above ) depicted. The Alpha Magnetic Spectrometer ( AMS / AMS-02 ), being equated to that of the Hubble space telescope, actually holds far more technological advancements from CERN and is solely designed to focus on subatomic particles surrounding antimatter issues.

U.S. Space Shuttle Endeavor mission STS-134 was scheduled to launch on April 14, 2011 but was delayed until the end of April 2011, but then was delayed yet again until May 16, 2011. Why so many delays and reschedulings?

Earth anti-matter issues are rarely addressed by the mainstream news media with the public, however in-lieu of the recent NASA public warning that it is expecting a ‘significant’ “solar flare” to erupt, coming bound for Earth, as something “we all need to be concerned about,” the Alpha Magnetic Spectrometer ( AMS ) having just been recently placed onboard the U.S. Space Shuttle Endeavour mission – scheduled to deliver the AMS aboard the International Space Station ( ISS ) – is something the public really needs to take a closer look at.

AntiUniverse Here We Come by, Eugenie Samuel Reich

May 4, 2011

A controversial cosmic ray detector destined for the International Space Station will soon get to prove its worth.

The next space-shuttle launch will inaugurate a quest for a realm of the Universe that few believe exists.

Nothing in the laws of physics rules out the possibility that vast regions of the cosmos consist mainly of anti-matter, with anti-galaxies, anti-stars, even anti-planets populated with anti-life.

“If there’s matter, there must be anti-matter. The question is, where’s the Universe made of antimatter?” says Professor Samuel C.C. Ting, a Nobel prize winning physicist at the Massachusetts Institute of Technology ( MIT ) in Cambridge, Massachusetts. But most physicists reason that if such antimatter regions existed, we would have seen the light emitted when the particles annihilated each other along the boundaries between the antimatter and the matter realms. No wonder the Professor Samuel C.C. Ting brainchild, a $2,000,000,000 billion dollar space mission was sold ‘partly on the promise of looking for particles emanating from anti-galaxies’, is fraught with controversy.

Professor Ting’s project, however has other ‘more mainstream scientific goals’ so, most critics of which held their tongues last week as the U.S. Space Shuttle Endeavour STS-134 mission – prepared to deliver the Alpha Magnetic Spectrometer ( AMS version, known as the AMS-02 ) to the International Space Station ( ISS ) – flight was delayed ( because of problems ) until later this month ( May 2011 ).

Pushing The Boundaries

Seventeen ( 17 ) years in the making, the Alpha Magnetic Spectrometer ( AMS ) is a product of the former NASA administrator Dan Goldin quest to find remarkable science projects for the Internation Space Station ( ISS ) and of the Ting fascination with anti-matter.

Funded by NASA, the U.S. Department of Energy ( DOE ), plus a sixteen ( 16 ) country consortium of partners, the Alpha Magnetic Spectrometer ( AMS ) has prevailed – despite delays and technical problems – along with the doubts of many high-energy and particle physicists.

“Physics is not about doubt,” says Roberto Battiston, deputy spokesman for the Alpha Magnetic Spectrometer ( AMS ) and physicist at the University of Perugia, Italy. “It is about precision measurement.”

As the Alpha Magnetic Spectrometer ( AMS ) experiment headed to the Space Shuttle Endeavour launch pad, Roberto Battiston and other scientists were keen to emphasize the Alpha Magnetic Spectrometer ( AMS ) ‘unprecedented sensitivity’ to the gamut of cosmic rays, that rain down on Earth, that should allow the Alpha Magnetic Spectrometer ( AMS ) to perform two ( 2 ) things:

1. Measure Cosmic Ray High-Energy Charged ‘Particles’ and ‘Properties’ ( thereof ), sent from:

– Sun ( Earth’s ); – Supernovae ( distant ); and, – γ-ray bursts.

AND,

2. Detect AntiMatter ( errant chunks ), sent from the:

a. Universe ( far-away ).

Cosmic rays ( on Earth ) can only be indirectly detected by their showers of ‘secondary particles’ produced – when slamming into molecules of atmosphere in high regions above the Earth, but the Alpha Magnetic Spectrometer ( AMS ) in space will get an undistorted view.

“We’ll be able to measure ( solar ) Cosmic Ray Flux very precisely,” says collaboration member physicist Fernando Barão of the Laboratory of Instrumentation and Experimental Particle Physics in Lisbon, Spain. “The best place ( for detecting this ) is to be in ‘space’ because you don’t have Earth’s atmosphere that is going to destroy those cosmic rays.”

No matter what happens, with the more speculative search for antimatter, the Alpha Magnetic Spectrometer ( AMS ) should produce a definitive map of the cosmic ray sky – helping to build a kind of ‘astronomy not dependent on light’.

Alpha Magnetic Spectrometer ( AMS ) consists of a powerful permanent magnet surrounded by a suite of particle detectors.

Over 10-years ( or more ), that the Alpha Magnetic Spectrometer ( AMS ) experiment will run, the Alpha Magnetic Spectrometer ( AMS ) magnet will bend the paths of cosmic rays by an amount that reveals their energy and charge, thereby their identity.

Some will be ‘heavy atomic nuclei’, while others ( made from anti-matter ), will reveal themselves by ‘bending in the opposite direction’ from their ‘matter’ counterparts ( see, e.g. cosmic curveballs ).

By ‘counting positrons’ ( i.e. antimatter ‘electrons’ ), the Alpha Magnetic Spectrometer ( AMS ) could also ‘chase a tentative signal of dark matter’, the so-far ‘undetected stuff’ thought to account for ‘much of the mass of the Universe’.

In 2009, Russia and Italy researchers – with the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics ( PAMELA ) onboard a Russia satellite – published evidence of an ‘excess amount of positrons in the space environment surrounding Earth’ ( O. Adriani et al. Nature 458 , 607–609; 2009 ). One potential source of this is the ‘annihilation of dark-matter particles’ within the ‘halo enveloping our Galaxy’.

Another speculative quest, is to follow up on hints of ‘strange matter’, a ‘hypothetical substance’ that should be found in ‘some collapsed stars’ containing ‘strange quarks’, ‘up quarks’ and ‘down quarks’ – within ordinary nuclei.

NASA Alpha Magnetic Spectrometer ( AMS ) program manager Mark Sistilli says hints of ‘strange matter’ were seen – during a 1998 pilot flight of the Alpha Magnetic Spectrometer ( AMS / AMS-01 ) aboard the Space Shuttle, however NASA determined results ‘too tentative to publish’.

Because the Alpha Magnetic Spectrometer ( AMS / AMS-02 ) status was made as an “exploration mission,” the Alpha Magnetic Spectrometer ( AMS ) ‘did not need to follow’ “peer review” NASA would ‘normally have required’ for a ”science mission.”

But Sistilli emphasizes the Alpha Magnetic Spectrometer ( AMS ) earned flying colors from committees convened by the U.S. Department of Energy ( DOE ), which is supplying $50,000,000 million of the funding.

Now their ( DOE ) confidence will be put to the test.

While for some it may appear strangelet subatomic antimatter particle research is for advancing our knowledge of unlocking the secrets of life in the Universe, others are still asking NASA what they really know is behind ‘why’ an ‘expected significant’ Solar Energetic Particle Event ( SEPE ) is something “we all need to be concerned about” on Earth.

With Solar Energetic Particle Event ( SEPE ) high-energy effects capable of disrupting Earth ground-based and space-based electrical components and electricity grid infrastructure systems for up to 10-years, many wonder why billions upon billions of dollars were and are still being pumped into the CERN project studying ‘strangelets’ and want to know just why we need ‘more immediate information detection capabilities’ on high-energy solar flare proton and electron ejections coming toward Earth soon, which NASA and other agencies ‘know far more about’ than they are willing to tell the public.

How advanced has government authorities grown from private-sector science and technology knowledge? The United States has already mapped internal magma flows of the Sun.

How could the U.S. government possibly ‘see inside the Sun’ to know when a coronal mass ejection from a solar flare would occur in the future?

In layman terms, for government it was like looking through a clear glass Pyrex bowl positioned atop a stove burner, watching as water starts to boil inside it, and then predicting – based on the flame heating it the water – when bubbles will come to the surface, when one takes into account a government ’ground-based’ ( does ‘not’ require ‘space-based placement’ ) observatory telescope equipped with a “super lens” used for imaging ( observing ) ‘objects at great distances inside matter’ – a “superlens” that now even ‘defies light-speed’ and ‘matter’.

Optical Antimatter Structure Shows The Way For New Super Lens by, Aditi Risbud

April 21, 2009

A device, made from alternating layers of ‘air’ and ‘silicon photonic crystal’, behaves like a ‘super lens’ – providing the first experimental demonstration of optical antimatter.

Scientists at Berkeley Lab ( Berkeley, California, USA ) and the Institute for Microelectronics and Microsystems ( CNR ) in Naples, Italy have experimentally demonstrated – for the first time – the ‘concept of optical antimatter’ by ‘light traveling through a material without being distorted’.

By engineering a material focusing light through its own internal structure, a beam of light can enter and exit ( unperturbed ) after traveling through millimeters of material.

For years, optics researchers have struggled to bypass the ‘diffraction limit’, a physical law restricting imaging resolution to about 1/2 the wavelength of light used to make the image.

If a material with a negative index of refraction ( a property describing how light bends as it enters or exits a material ) could be designed, this diffraction hurdle could be lowered.

Such a material could also behave as a superlens, useful in observing objects from imaging equipment with ‘details finer than allowed by the diffraction limit’, a physical law restricting imaging resolution to about 1/2 the wavelength of light used to make the image.

Despite the intriguing possibilities posed, by a substance with a negative index of refraction, ‘this property is inaccessible through naturally occurring ( positive index ) materials’.

During the mid 1990s, English theoretical physicist Sir John Pendry proposed his clever ‘sleight of light’ using so-called metamaterials – engineered ‘materials’ whose underlying structure ‘can alter overall responses’ to ‘electrical fields’ and ‘magnetic fields’.

Inspired by the Sir John Pendry proposal, scientists have made progress in scaling metamaterials from microwave to infrared wavelengths while illuminating the nuances of light-speed and direction-of-motion in such engineered structures.

“We’ve shown a ‘completely new way to control and manipulate light’, ‘using a silicon photonic crystal’ as a ‘real metamaterial’ – and it works,” said Stefano Cabrini, Facility Director of the Nanofabrication Facility in the Molecular Foundry, a U.S. Department of Energy ( DOE ) User Facility located at Lawrence Berkeley National Laboratory ( LBNL ) providing support to nanoscience researchers around the world.

“Our findings will open-up an easier way to make structures and use them effectively as a ‘super-lens’.”

Through the Molecular Foundry user program, Cabrini and post-doctoral researcher Allan Chang collaborated with Vito Mocella, a theoretical scientist at the Institute of Microelectronics and Microsystems ( CNR ) in Naples, Italy to fabricate a 2 X 2 millimeter device consisting of alternating layers of air and a silicon based photonic crystal containing air holes.

Using high precision nanofabrication processes, the team designed the spacing and thicknesses of each layer to behave like the metamaterial Sir John Pendry had envisioned.

This device was then used to focus a beam of near-infrared ( I-R ) light, essentially ‘annihilating’ 2 millimeters of ‘space’.

“Now that we have a prototype to demonstrate the concept, our next step will be to find the geometry and material that will work for visible light,” said Cabrini.

Along with possibilities in imaging, the researchers’ findings could also be used to develop hybrid negative-index and positive-index materials, Cabrini added, which may lead to novel ‘devices’ and ‘systems’ unachievable through either material alone.

“Self-collimation of light over millimeter-scale distance in a quasi zero average index metamaterial,” by Vito Mocella, Stefano Cabrini, Allan S.P. Chang, P. Dardano, L. Moretti, I. Rendina, Deirdre Olynick, Bruce Harteneck and Scott Dhuey, appears in Physical Review Letters available in Physical Review Letters online.

If the public could keep its eye open for one second, it would see what is coming at them before it hits them with a surprise that only government knows anything about, but governments have spoken mysteriously to citizens for a very long time, but perhaps a mere fact ’known today’ may eventually come as no surprise to many whom would have otherwise been kept in the dark while only a few know far more about what awaits the masses.

Perhaps, people may begin asking more questions of their country’s agencies spending so much money so quickly for apparently some ‘mysterious emergency purpose’, and if not for some ‘mysterious emergency purpose’, why is so much money being spent on science and space projects while the global public is told about serious government budget cutbacks causing so many people to suffer? If there is no ’emergency’, then people should know ‘why they are suffering financially more’ – just for the sake of ‘growing science experiment budgets’? Might be a good idea for everyone to begin keeping their eyes open a little more often and trained on something more than light-hearted mainstream media news comedy broadcasts.

If people think they get real serious about ‘what they know’ as told on television news broadcasts, imagine how much more serious they will become when they learn about what they ‘were not told’?

Think about it. How Fast Is Technology Growing? Just beginning to grasp something ‘new’? Now think about something even newer than the Large Hadron Collider ( LHC ) at CERN, the Relativistic Heavy Ion Collider ( RHIC ) that added its Solenoidal Tracker At RHIC ( STAR ) claiming to ‘reverse time’ by ultra super computers reconstructing sub-atomic particle interactions producing particles – emerging from each collision – that STAR is believed to be able to ‘run time backward’ in a process equated to examining final products coming out-of a factory that scientists and physicists have no idea ’what kinds of machines produced the products’. Basically, they are developing items so fast, they do not know how they were formed, much less what the capabilities are. Fact is, ’they could easily produce a monster’ and ‘not know what it is until after they are eaten by it’. Scary, really, like kids being given matches to play with.

They are being educated beyond their own intelligence, so much so and to the point by which scientists and physicists ’cannot even grasp what ‘it’ is they’re looking at – much less know what they are trying to manipulate to ‘see what it does next’ – nevertheless they are conducting experiments like children playing with dynamite.

Think this is science fiction? Think they are mad scientists at play? Check the research reference links ( below ). Think antimatter technology has advanced alot since you began reading this report? calculate ‘more’ because the public does not even know half of it.

CERN has been operating since 2002, and the “SuperLens” was worked-on ‘before’ 2002, making ‘both’ today now 10-years old.

Want newer ‘news’?

Superlenses – created from perovskite oxides – are simpler and easier to fabricate than ‘metamaterials’.

Superlenses are ideal for capturing light travelling in the mid-infra-red ( IR ) spectrum range, opening even newer technological highly sensitive imaging devices, and this superlensing effect can be selectively turned ‘on’ and ‘off’, opening yet another technology of ‘highly dense data storage writing’ for ‘far more advanced capability computers’.

Plasmonic whispering gallery microcavities, consisting of a silica interior coated with a thin layer of silver, ‘improves quality by better than an order of magnitude’ of current plasmonic microcavities. and paves the way for ‘plasmonic nanolasers’.

Expand your knowledge, begin researching the six ( 6 ) reference links ( below ) so that the next time you watch the ‘news’ you’ll begin to realize just how much you’re ‘not being told’ about what is ‘actually far more important’ – far more than you’re used to imagining.

Secret HFSE Properties Part 1

Secret HFSE Properties – Part 1
Emerging Superconducting Magnetic Element Properties
by, Concept Activity Research Vault ( CARV )

December 1, 2011 16:08: 42 (PST ) Updated ( Originally Published: December 9, 2010 )

CALIFORNIA, Los Angeles – December 1, 2011 – In 1961, BELL LABORATORIES ( USA ) physicist Eugene Kunzler and co-workers discovered that niobium–tin continued exhibition of superconductivity while in the presence of strong electric currents and magnetic fields, which made niobium-tin the first [ 1st ] material used to support High Field Strength ( HFS ) electrical currents and magnetic field strengths necessary for use in high-power electro-magnets and electrical power machines.

20-years later, the aforementioned discovery allowed production of niobium doped metallic wire wrapped into multi-strand form cables wound into coils creating powerful electro-magnetic force applications seen in particle accelerators, particle detectors, and rotating machines.

High Field Strength Element ( HFSE ) Niobium ( Nb ) holds far greater use from such properties than most professionals and the public realize so, before advancing any further on this subject, a basic foundation of understanding on such materials, elements and their valuable properties must be realized about this ‘extremely old Earth energy resource’, ‘how to harvest it ( from its original molten state )’, ‘how to capture and contain its volatile properties’, and then ‘transform it into applications’ for transportation – ‘yet unrealized factual knowledge’ on this extremely low-cost extremely powerful high-energy resource.

Niobium ( Nb ) –

[ photo ( above ): Niobium ( .9995 fine) crystals ( click to enlarge ) ]

Titanmagnetite (aka) Titanomagnetite mineral, under Fluorescent X-Ray Spectrography ( XRS ), holds detected high measurements [ from 350 ppm ( parts per million ) up to 1,000 ppm ] of the geochemical High Field Strength Element ( HFSE ) Niobium [ Nb ].

‘Where’ does such a ‘mineral’ ( titanmagnetite ) ‘element’ ( niobium ) originate? Volcanic magma.

‘Where’ are specific locations holding volcanic magma Niobium element properties that possess even ’higher field strength’ magnetics – ‘at least’ six ( 6 ) times greater? The Mariana Trench or other ultra-deep sea continental plate arc locations where volcanoes exist either ‘quite active’ or ‘somewhat dormant’.

Readers may begin to awaken from any slumber when they realize that ultra-deep sea ground trench ( arc ) volcano magma, naturally located nearer to the planet Earth molten liquid superconducting magnetic High Field Strength Element ( HFSE ) ’core’, sees element properties of Niobium absorbing far purer forms of High Field Strength Element ( HFSE ) magnetic properties while within its ‘natural molten liquid state’. Interestingly, nowhere else ‘above ultra-deep sea Earth elevations’ obtain more natural energy power.

How can such a volatile molten resource be ‘excavated’ while simultaneously being isolated from any exposure to contaminations from ‘seawater’, ‘oxygen’ or other environmentals to harness high-energy properties?

The molten material would  additionally have to be placed into a likewise uncontaminated ‘ultra-clean chamber’, whereupon after transport, ’high-energy properties extraction’ must undergo a ‘seamless application process’ for utilization.

What type of use? More basic fundamentals must be initially understood so, let’s begin by taking a look at what’s bubbling out of ultra-deep sea volcano vents and instantly becoming contaminated by seawater ( below ):

[ photo ( above ): Ultra-Deep Sea Trench Arc Volcanic Magma Vent ( click to enlarge ) ]

Preliminary report Part 1 ( herein ) displays a photograph of an above-ground volcano eruption in Iceland experiencing plenty of superconducting High Field Strength Element ( HFSE ) property fireworks, however far too little information is ever realized by the public about what ultra-deep sea trench arc volcano magmatic material element properties hold ‘naturally’ as primary key elements to a variety of other advancements.

Volcanic magma, in later stage differentiation, sees Niobium [ Nb ] and Titanium [ Ti ] ratios ‘increase’ five [ 5 ] to six [ 6 ] times above normal ( dry magma melts ).

To comprehend this, along with the importance of harnessing natural Earth high-energy magnetic properties, a basic understanding must be reached from what science, physics and astrophysics indications always seem to avoid for the public.

The purpose of this preliminary report Part 1 is to bring rare knowledge into better public understanding while stimulating solution-minded professionals wishing more done.

Have scientists, physicists, and astrophysicists ‘missed some major solution’ in their discoveries? Are portions of certain discoveries ‘kept quite’ considering serious repercussions? While highly doubtful that any small discovery having a major impact missed any application outlook, ramifications nevertheless are considered by professionals on whether a socio-economic impact will allowed to be proven helpful or otherwise.

Good advice may be to buckle your seatbelt because you are about to venture into some information few have ever known about. Whether most of those reading this may be able to absorb this information ( below ) now, or later, it is suspected that after much easier reading comes in Part 2 through Part 5, most will probably refer back to Part 1 ( herein ).

Preliminary Report ( Part 1 of 5 )

Introduction –

High Field Strength Elements ( HFSE )

Niobium

Niobium enrichment, is possible, using two ( 2 ) natural rock-forming minerals:

– Titanmagnetite [ 350 ppm – 1000 ppm Nb ( Niobium ) ]; and, – Kaersutite [ 38 ppm – 50 ppm Nb ( Niobium ) ].

General Information:

Rock-forming Minerals: Titanmagnetite ( element symbols: Ttn/Mag ), and Kaersutite ( Krs ). Elements [ symbols ]: Titanite ( Ttn ), Magnetite ( Mag ) Geochemical Element [ symbols ]: Niobium ( Nb )

Studies & Resolutions –

Subject: Natural High Field Strength Element ( HFSE ) Materials

Titanmagnetite [ Ttn/Mag ] is a natural super-magnetic mineral, that later experiences a geochemical alteration reducing its magnetic High Field Strength Element ( HFSE ) Niobium ( Nb ) properties, as it exits ultra-deep sea arc volcanic magma influenced by hydrothermal fluid seawater ( see “Findings” below ). In its natural magma state where Titanmagnetite ( Ti/Mag ) holds its 6 [ X ] times greater High Field Strength Element ( HFSE ) Niobium ( Nb ) than above-ground.

Niobium ( Nb ) High Field Strength Element ( HFSE ) properties can be enhanced even greater by adding only one ( 1 ) mineral, Kaersutite ( Krs ).

For applications, extracting this natural combinatoric high-energy power may not easily be obtained.

Extraction Processes: Capturing Natural High Field Strength Elements ( HFSE )

Obtaining these properties may be resolved, however while natural initial ingress of high-temperature ( Tave 713° C to Tave 722° C ) fluid occurences at liquid melts [ magma ] have seen amphibole-plagioclase thermometry suggests ‘fracture and grain’ boundary ‘permeability’ – with seawater derived fluids – ‘open’ over similar temperature interval, however venturing into ultra-deep sea trench arcs and then burroughing into natural state volcanic magma dome vents capturing natural essence of titanmagnetite, and then containing it for processing HFSE properties further may be difficult so, is there an alternative to this type of extraction?

Above-ground experiment observations see major trace geochemical element fractionation trends in bulk rocks and minerals reproduced by Rayleigh fractional crystallization from dry [ magma ] melts ( < 0.5 wt. % H2O ) with oxygen fugacities of one [ 1 ] unit below the Quartz [ Qtz ] – Fayalite [ Fa ] – Magnetite [ Mag ] buffer ( QFM – 1 ).

Die verteilung des niobs in den gesteinen und mineralen der alkalibasalt-assoziation der hocheifel by, Hans Gerhard Huckenholz

Publication Date: August 1965

Abstract –

Niobium [ Nb ] contents are determined by the method of fluorescent X-ray spectrography [ FXRS ] for several rock types from the Tertiary Hocheifel volcanic province ( Western Germany ).

Alkalic olivine basalt, contains:

65 ppm Niobium [ Nb ] ( 7 samples );  69 ppm hawaiite ( 4 samples );  86 ppm mugearite ( 3 samples );  95 ppm trachyte ( 5 samples ); 77 ppm basanitoid ( 6 samples );  65 ppm ankaramite ( 2 samples ); 110 ppm hauyne-bearing alkali basalt ( 2 samples ); and,  86 ppm a monchiquite dike.

Niobium enrichment, is observed in the alkalic olivine basalt trachyte [ magma ] series where, in later stage differentiation, Nb [ Niobium ] / Ti ratio increases five [ 5 ] to six [ 6 ] times.

Alkalic olivine basalt magma, however becomes poorer [ less rich ] in niobium [ Nb ] by accumulation of:

– olivine [ 10 ppm Nb ( niobium ) ]; and, – clinopyroxene [ 20 ppm Nb ( niobium ) ].

Enrichment of niobium [ Nb ] is possible by taking-up titanmagnetite ( 350 ppm – 1000 ppm Nb [ Niobium ] ) and kaersutite ( 38 ppm – 50 ppm Nb [ niobium ] ) without olivine and clinopyroxene ( ankaramite HF 5, and the basanitoids ).

The most Nb [ Niobium ] bearing rock-forming mineral is titanmagnetite, containing 65%  to 85% niobium ( in volcanic rock ), however ground-mass clinopyroxene has contents of Niobium [ Nb ] up to 45 ppm, and feldspars have contents of Nb [ Niobium ] up to 67 ppm.

Abstract

In this study we attempt to contribute to the understanding of a prominent feature, namely the Nb [ Niobium ] – Ta [ Tantalum ] depletion, in arc magmatic trace element geochemistry.

Traditionally, this depletion is explained by residual mantle-wedge phases with Nb [ Niobium ] and Ta [ Tantalum ] affinities, such as titaniferous ilmenite [ Ilm ], rutile [ Rt ] or titanite [ Ttn ], or by an amphibole.

Here, we propose a mechanism – long advocated – to explain the calc-alkaline trend ( Bowen vs. Fenner ) in MgO – FeO ( total Fe ) – ( Na2O + K2O ) ternary diagram by early crystallization and separation of magnetite in ‘subduction zone magmas’ associated with ‘high oxygen’ fugacity ‘environments’.

In support of our hypothesis, we provide high-precision multiple trace element data, including the High Field Strength Elements ( HFSE ), in separated magnetites and mafic mineral phases from mafic ‘magmatic enclaves’ associated with ‘tonalite suites’ of two [ 2 ] different ‘magmatic arcs’, the:

– Tanzawa Complex of the Izu-Tanzawa Collision Zone in Japan; and, – Ladakh Batholith Complex of NW Himalayas.

The Tanzawa Complex is composed of diverse rock suites with SiO2 varying from 43% – 75%, ranging from hornblende gabbro through tonalite to leuco-tonalite. The geochemical characteristics of low K – tholeiites, enrichment of Large Ion Lithophile Elements ( LILE ), and depletion of HFSE [ High Field Strength Elements ] in rocks of this plutonic complex are similar to those observed in the volcanic rocks of the IBM arc.

The Ladakh batholith Complex is one of the granitic belts exposed north of the Indus-Tsangpo suture zone in Ladakh, representing calc-alkaline plutonism related to the subduction of the Neotethys floor in Late Cretaceous. This batholith comprises predominantly I-type granites with whole rock delta delta 18O values of 5.7-7.4 per mil, without major contribution from continental crustal material.

In separated magnetites, from five [ 5 ] gabbros of the Tanzawa tonalite-gabbro complex and from three [ 3 ] tonalitic gabbros of the Ladakh batholith, we analyzed 22 trace elements by ICP-MS, including:

Nb [ Niobium ]; Ta [ Tantalum ]; Hf [ Hafnium ]; and, Zr [ Zirconium ].

In NMORB [ N Mid-Ocean Ridge Basalt ] normalized plots, the trace element patterns of all the magnetites analyzed show enrichment ( 5X NMORB ), in:

Nb [ Niobium ]; Ta [ Tantalum ]; Pb [ Lead ]; Sr [ Strontium ]; and, ( 2X NMORB ), in: Zr [ Zirconium ] with characteristically high Nb [ Niobium ], Ta [ Tantalum ] and Zr[ Zirconium ] / Hf [ Hafnium ] ratios.

In contrast, the patterns show anomalously low ( less than 0.1 NMORB ), in:

La [ Lanthanum ]; Ce [ Cesium ]; Pr [ Praseodymium ]; Nd [ Neodymium ]; Sm [ Samarium ]; and, Hf [ Hafnium ] concentrations.

It is noteworthy that in the normalized trace element plot, all the magnetites show ‘high’ Nb [ Niobium ] / Ta ratios, and in contrast with high Ta / Nb [ Niobium ] ratios were observed in typical arc [ volcanic ] magmas.

These data support our hypothesis, that:

Magmatic crystallization, of Fe [ Iron ] – Ti [ Titanium ] oxides ( under high oxygen fugacity conditions ) during ‘initial crystallization and formation’ ( of the Izu-Bonin and Ladakh-type arc batholiths ) may be the primary cause of depletion of HFSE [ High Field Strength Elements ] in later magmatic differentiates of less mafic and more felsic granitic arc rocks.

Abstract

The petrographic or chemical zonation of plutons, has been widely studied and used to constrain petrogenetic processes and emplacement mechanisms.

The time involved in modal data collection, as well as the cost of chemical analyses, makes the search for pluton-scale zoning patterns the exception rather than the norm in ‘magmatic arc studies’, however magnetic susceptibility ( Km ) of plutonic rocks – both magnetite bearing and magnetite free – can be an invaluable tool to quickly assess the internal organization of any pluton.

New field observations, new magnetic mineral data, and reprocessed Km data on the Barcroft granodiorite pluton ( White Mountains, California ) are presented.

The average Km of 660 specimens from 76 stations ranges from 140 x 10-6 [ SI ] to 75000 x 10-6 [ SI ] with an average at about 16800 x 10-6 [ SI ].

The distribution of Km is unimodal.

The hysteresis parameters of the Barcroft rocks indicate that Km is controlled mainly by multi-domain magnetite.

The contribution of mafic silicates ( biotite and hornblende ) to Km ranges from 0.4 to 99%, with an average at about 1.8%.

As in many other ferromagnetic ( i.e. magnetite – bearing ) plutons, Km variations reflect different amounts of magnetite which itself results from petrographic variations.

This is supported by the positive correlation between major oxide variations ( e.g., SiO2, FeO ) and Km.

A new Km map of the Barcroft pluton shows several important features including, a:

(a) Low Km zone in the SW corner of the pluton, near areas that exhibit economic mineralization possibly related to hydrothermal fluids;

(b) Few isolated anomalies that may be attributed to transformation of normal magnetite into lodestone;

(c) North south high Km ridge that could possibly result from local mingling between the main granodiorite rock type and syn-plutonic mafic dikes;

(d) Broad reverse Km zonation ( i.e. higher Km in the centre ); and,

(e) Possible ‘positive correlation between Km’ and ‘topographic elevation ( between 5,000 and 13,000 feet )’, which could be explained by a higher fO2 at a higher structural level in the chamber.

These preliminary results suggest that, the:

(1) Syn-plutonic diking may play a significant role in the geochemical differentiation of granodiorite plutons;

(2) Classic dichotomy between ilmenite [ Ilm ] series and magnetite [ Mag ] series of granitoids might at least – to some extent – depend on the ‘exposure level’ if such intrusions are confirmed to be vertically differentiated; and,

(3) Mapping Km in a ferromagnetic pluton can be an efficient tool to constrain its internal organization.

Abstract

The geochemistry and petrology of the lower oceanic crust record information about the compositions of melts extracted from the mantle, how these melts mix and crystallize, and the role of hydrothermal circulation in this portion of the crust.

Unfortunately, lower oceanic crust formed at fast spreading ridges is rarely exposed at the seafloor making it difficult to study these processes.

At Hess Deep, crust formed at the East Pacific Rise ( EPR ) is exposed due to the propagation of the Cocos-Nazca spreading center westward.

Here we review our state of knowledge of the petrology of lower crustal material from Hess Deep, and document new mineral major and trace element compositions, amphibole-plagioclase thermometry, and plagioclase crystal size distributions.

Samples from the deeper parts of the gabbroic sequence contain clinopyroxene that is close to being in trace element equilibrium with erupted basalts but which can contain primitive ( moderate Cr, high Mg# ) orthopyroxene and very calcic plagioclase.

Because primitive Mid-Ocean Ridge Basalts ( MORB / MORBs ) are not saturated with orthopyroxene or very calcic plagioclase this suggests that melts added to the crust have variable compositions and that some may be in major but not trace element equilibrium with shallow depleted mantle.

These apparently conflicting data, are most readily explained if some of the melt – extracted from the mantle – is fully aggregated within the mantle but reacts with the shallow mantle during melt extraction.

The occurrence of cumulates, with these characteristics, suggests that ‘melts added to the crust’ do not all get mixed with normal MORB [ Mid-Ocean Ridge Basalts ] in the Axial Magma Chamber ( AMC ), but rather that ‘some melts partially crystallize’ in isolation within the lower crust.

However, evidence that primitive melts fed the AMC [ Axial Magma Chamber ], along with steep fabrics in shallow gabbros ( from near the base of the dyke complex ), provides support for models in which crystallization within the AMC followed by crystal subsidence is also an important process in lower crustal accretion.

More evolved bulk compositions of gabbros ( from the upper than lower parts of the plutonic section ), are due to greater amounts of ‘reaction with interstitial melt’ and not because their parental melt had become highly fractionated through the formation of large volumes of cumulates deeper in the crust.

Amphibole-plagioclase thermometry confirms, previous reports, that the initial ingress of fluid occurs at high-temperatures in the shallow gabbros ( Tave 713° C ) and show that the temperature of amphibole formation was similar in deeper gabbros ( Tave 722°C ).

This thermometry also suggests that fracture and grain boundary permeability for seawater derived fluids was open over the same temperature interval.

Abstract

The origin of compositional gaps in volcanic deposits that are found worldwide, and in a range of different tectonic settings, has challenged petrologists since Daly’s first observations at mid-ocean ridges.

In the shield-forming Akaroa Volcano ( 9.6 – 8.6 Ma ) of Banks Peninsula ( New Zealand ), a dramatic compositional gap exists in both eruptive and co-genetic intrusive products between basalt and trachyte, and between gabbro and syenite respectively.

Rock compositions display mildly alkaline affinities ranging from picritic basalt, olivine alkali basalt, and hawaiite, to trachyte.

Intermediate mugearite and benmoreite ( 50 – 60 wt. % SiO2 ) are not exposed or absent.

Equivalent plutonic diorite, monzodiorite, and monzonite ( 45 – 65 wt. % SiO2 ) are also absent.

Previously, the formation of the more evolved trachyte and syenite has been ascribed to ‘crustal melting’, however our analysis of new major data and trace element data from bulk-rocks and minerals – of this hy-normative intraplate alkalic suite – provide evidence based on crystal fractionation and punctuated melt extraction for an alternative model.

In bulk rocks observed major and trace element fractionation trends can be reproduced by Rayleigh fractional crystallization from dry melts ( < 0.5 wt. % H2O ) at oxygen fugacities of one [ 1 ] unit below the Quartz [ Qtz ] – Fayalite [ Fa ] – Magnetite [ Mag ] buffer ( QFM – 1 ).

The results of our MELTS models are in agreement with experimental studies, and indicate a fractionation generated compositional gap where trachytic liquid ( 62 – 64 wt. % SiO2 ) has been extracted after the melt has reached a crystallinity of 65% – 70 %.

The fractionated assemblage, of:

– clinopyroxene [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ]; – olivine [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ]; – plagioclase; – magnetite; and, – apatite.

All [ of the aforementioned ] are left in a mafic cumulate residue ( 44 – 46 wt. % SiO2 ).

Calculated values of specific trace and minor elements ( Sr [ Strontium ], Cr [ Chromium ], P [ Phosphorus ] ) from a theoretical cumulate are consistent with measured concentrations from cumulate xenoliths. ‘ Compositional trends from individual mineral analysis are also supportive of fractional crystallization, but illustrate a disrupted ‘liquid line of decent for each mineral phase.

Olivine [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ] compositions progressively decrease in Mg [ Magnesium ] concentration ( Fo83-42 ) in basaltic [ magma ] melts and shows high Fe [ Iron ] concentration in trachytic melts ( Fo5-10 ).

Clinopyroxene [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ] analyses also displays higher Fe [ Iron ] / Mg [ Magnesium ] ratios in more evolved rocks.

Ternary feldspar [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ] compositions shift from plagioclase ( An84-56 ) in basalt to alkali feldspar ( Or8-65Ab53-33An39-2 ) [ depletes High Field Strength Element ( HFSE ) Neobium ( Nb ) ] in trachyte, but also lack the intermediate compositions.

On the other hand, analysis of mafic cumulate xenoliths reflect more evolved mineral compositions – towards the rim than volcanic equivalents – and complete observed fractionation trends.

In summary, our results indicate that these compositional gaps formed from punctuated melt extraction within an optimal crystal fraction window ( 60% – 70 % crystallinity ).

Abstract

The Aurora volcanic field, located along the northeastern margin of Mono Lake in the Western Great Basin, has erupted a diverse suite of high-K and shoshonitic lava types, with 48 to 76 wt. % SiO2, over the last 3,600,000 million years.

There is no correlation between the age and composition of the lavas.

Three-quarters of the volcanic field consists of evolved ( < 4 wt. % MgO ) basaltic andesite and andesite lava cones and flows, the majority of which contain sparse, euhedral phenocrysts that are normally zoned; there is no evidence of mixed, hybrid magmas.

The average eruption rate over this time period was ˜200 m3/km2/year, which is typical of continental arcs and an order of magnitude lower than that for the slow-spreading Mid-Atlantic Ridge.

All of the Aurora lavas display a trace-element signature common to subduction-related magmas, as exemplified by Ba [ Barium ] / Nb [ Niobium ] ratios between 52 and 151.

Pre-eruptive water contents ranged from 1.5 wt. % in plagioclase – rich two-pyroxene andesites to ˜6 wt. % in a single hornblende lamprophyre and several biotite-hornblende andesites.

Calculated oxygen fugacities fall within 0.4 and + 2.4 log units of the Ni-NiO [ Nickel and Nickel-Oxygen ] buffer.

The Aurora potassic suite, follows a classic calc-alkaline trend in a plot of FeOT / MgO vs. SiO2 and displays linear decreasing trends in FeOT and TiO2 with SiO2 content, suggesting a prominent role for Fe [ Iron ] – Ti [ Titanium ] oxides during differentiation.

However, development of the calc-alkaline trend – through fractional crystallization of titanomagnetite – would have caused the residual liquid to become so depleted in ferric iron that its oxygen fugacity would have fallen several log units below that of the Ni [ Nickel ] – NiO [ Nickel – Oxygen ] buffer.

Nor can fractionation of hornblende be invoked, since it has the same effect – as titanomagnetite – in depleting the residual liquid in ferric iron, together with a thermal stability limit that is lower than the eruption temperatures of several andesites ( ˜1040 1080°C ; derived from two-pyroxene thermometry ).

Unless some progressive oxidation process occurs, fractionation of titanomagnetite – or hornblende – cannot explain a calc-alkaline trend in which all erupted lavas have oxygen fugacites ≥ the Ni-NiO [ Nickel – Nickel-Oxygen ] buffer.

In contrast to fractional crystallization, closed system equilibrium crystallization will produce residual liquids with an oxygen fugacity that is similar to that of the initial melt.

However, the eruption of nearly aphryic lavas argues against tapping from a magma chamber during equilibrium crystallization, a process that requires crystals to remain in contact with the liquid.

A preferred model involves the accumulation of basaltic magmas at the mantle crust interface, which solidify and are later remelted during repeated intrusion of basalt.

As an end – member case, closed – system equilibrium crystallization of a basalt, followed by equilibrium partial melting of the gabbro will produce a calc-alkaline evolved liquid ( namely, high SiO2 [ Silicon-Oxygen / Oxide ] and low FeOT / MgO ) with a relative f O 2 ( corrected for the effect of changing temperature ) that is similar to that of the initial basalt.

Differentiation of the Aurora magmas by repeated partial melting of previous underplates in the lower crust, rather than by crystal fractionation in large stable magma chambers, is consistent with the low eruption rate at the Aurora volcanic field.
