VANUATU ISLAND, Port Vila — December 26, 2010 — It may be difficult for some to realize this report is ‘not science fiction’, but within the Pacific Ocean volcanic arc “Ring of Fire,” in just a few days of November 26, 2005 Vanuatu Island residents did not even realize their island Lake Voui was where its ’new inner island mountain’ Mt. Manaro (aka) Aoba volcano was ‘created in merely a matter of a few days’ after their 420-year old volcano highly volatile magma was mixed into their lakebed hydrochloride sulfuric acid geochemicals, only just learned last year ( 2009 ),  as the actual trigger mechanism setting off the incredibly explosive eruption.

The Ambae volcano vent inside the Lake Voui new island Mt. Manaro ( also known as ) Aoba volcano is the largest basaltic shield volcano in the New Hebrides arc. Aoba volcano is one of the largest active volcano caldera crater lakes in the world today.

Warning Signs –

On February 16, 2005 a succession of earthquakes were felt by the Vanuatu islanders during the evening. Several days later, a seismometer was installed on the north coast of Vanuatu Island where no ‘significant seismic activity’ was recorded there prior to the November 26, 2006 volcano eruption.

On October 5, 2005 NASA Earth Observing System ( EOS ) AM-1 satellite ( TERRA ) carried onboard a Moderate Resolution Imaging Spectro-Radiometer ( MODIS ) that first ( 1st ) detected volcano Ambae volcano summit Lake Voui area registering a thermal imaging anomaly ( highly volatile magma emission degassing ), which was “8-days” ‘before’ the Ambae volcano erupted in the middle of Lake Voui on November 26, 2005 when Vanuatu Island residents were rocked with a Volcano Alert Level 2 ( representating the level of volcanic eruption activity ).

Shockingly, on November 21, 2005 – “2-days” after the November 19, 2005 thermal imaging anomaly ( highly volatile magma emission degassing ) – and yet still “6-days” ‘before’ the eruption on November 26, 2005 – the MODIS SST ( MOD28L2 Infra-Red imaging sensor product ) later detected – in Lake Voui on Vanuatu Island – a ‘definite visual IR display’ of ‘strong hydrothermal activity’ reported only as an “anomaly” that was clearly seeing Ambae volcano ( GEO-REF coordinates: 167°50′E, 15°23′S ) ‘highly volatile magma degassing emissions’ entering the high chloride sulfuric acid contents of Lake Voui’ where mixing those two ( 2 ) ingredients would most certainly cause a phreatic explosion.

When Did The Public Know? –

It wasn’t until ‘after’ the November 26, 2005 phreatic ( violent ) explosion of the Ambae volcano vent inside Lake Voui that the Vanuatu Island government then began to take precautions, by:

– Evacuating nearly 4,000 people away from the immediate area; – Dispatching its own local volcanologists; – Asked the New Zealand government to contribute aid assistance; – Asked donor agencies for assistance contributions; and, – Asked other aid contributors to additional assist.

U.S. National Aeronautic And Space Administration ( NASA ) Notified The New Zealand Government When? –

The New Zealand Ministry of Foreign Affairs and Trade – via NZAID – contracted INSTITUTE OF GEOLOGICAL & NUCLEAR SCIENCES LTD. ( IGNS ) to mount a response dispatch of two [ 2 ] volcanologists [ Brad Scott ( E-MAIL: ) and Steve Sherburn ( seismologist ) ] assigned objectives that also included:

– Assisting Vanuatu Island geological and government emergency response organization interpretations of its Ambae volcano eruption;

– Providing detailed assessment of Vanuatu Island Ambae volcano eruption current activity levels; and,

– Offer some prognosis of future Ambae volcano activity.


– Temporary seismic monitoring system to collect activity data for assessments; and,

– Provide a foreseeable means how Vanuatu Island scientists could continue monitoring future activity.

Steve Sherburn and Brad Scott departed, for Vanuatu Island, with provided:

– Seismic recording systems ( 3 ); plus,

– Additional volcano monitoring tools.

Prior Incident Response Experience On Vanuatu Island –

Due to such a short lead-time notice [ <?> ], remoteness of the Ambae volcano location on Vanautu Island, and lack of volcanological ( historical ) data, Vanuatu Island was a challenging assignment – offset somewhat by Steve Sherburn ( seismologist ) and Brad Scott ( volcanologist ) past eruption monitoring and assessment experience on Vanuatu Island, Tonga and Papua New Guinea.

The INSTITUTE OF GEOLOGICAL & NUCLEAR SCIENCES LTD. ( IGNS ) – under New Zealand government contract – dispatched Brad Scott and Steve Sherburn whom upon arrival on Vanuatu Island found that one of Ambae volcano summit lakes named Lake Voui ( a 2 square kilometer and 150 meter deep chloride sulfuric acid lake ) was undergoing small-scale eruptions that in ‘just a few days’ grew into a ‘new volcano cone’ that became known as Mt. Manaro (aka) Aoba volcano mountain more than 656-feet wide and 229-feet tall.

On Vanuatu Island, Steve Sherburn and Brad Scott spent 6-days:

– Establishing seismic equipment; – Collecting and analyzing data; – Observing Ambae volcano eruptions; and, – Providing Ambae volcanic activity level status reports for the government of Vanuatu Island.

Support and data additional information were supplied, by:

– French [ Polynesia – Tahiti, Wallis and Futuna (aka) Fakauvea (aka) Fakafutuna Islands, Vanautu Island, Melanasia, Kanak ( formerly known as ) Canaque, Indonesia and Viet Nam populace ] scientists from Nouméa, New Caledonia; and,

– Staffers and students from Massey University, Manawatu campus in the Manawatu-Wanganui region City of Palmerston, North Island, New Zealand.

Then-secret use of Differential Optical Absorption Spectroscopy ( DOAS ) retrieval methods found sulphur dioxide column abundances from magma SO2 and H2S gas flux emission analysis, seismic data analysis, visual observations of Inter-établissements de Recherche pour le Développement ( IRD ) Nouméa, New Caledonia ( Nouvelle-Calédonie ) team of French scientists Ambae volcano historical activity review was followed by Ambae volcano activity level assessments.

Later, it was all declared a ‘small-scale eruption’ of ‘no major threat’ to the Vanuatu Island population, ‘after information began being passed on in bulletins’ ( with Bislma language translations ) to, the:

– Disaster Co-ordination Group ( Port Vila, Vanuatu Island ); – Government of Vanuatu Island; and, – Community of Vanuatu Island.

Vanuatu Island “Volcano Alert Level 2,” however ‘remained’ – until activity declined – as bulletins indicated.

Again on Vanuatu Island, GEOLOGICAL & NUCLEAR SCIENCES LTD. ( GNS ) marked as ‘important’ values to permanently monitoring ( over a period of time ) each active volcano for which activity has unique characteristics observed for correlating data on any changes in volcano geophysical measurements and behaviors.

As of November 25, 2006 the Ambae volcano Mt. Manaro island vent crater wall collapsed on one side opening-up its cauldron to a chloride sulfuric acid bath from Lake Voui halting its gasious plume cloud into the atmosphere.

Volcano Magma Knowledge Not Being Shared Why? –

In 2009, it was finally learned amongst public professionals that as the Lake Voui lake-bed received approaching degassed but ‘volatile-rich magma’ ( from the Ambae volcano ) that was the trigger mechanism to begin the surtseyan eruption of November 2005 on Vanuatu Island.

Plasma-Optical Emission Spectroscopy ( ICP-OES ) Technicon Auto-Analyzer II Analysis –

Even today magmatic–hydrothermal system eruption-related gas fluxes into the atmosphere and geochemistry associated therewith is sorely lacking professional knowledge throughout the world.

On December 25, 2010  shortly after midnight and approximately 140-miles south of Vanuatu Island – although nearer to the Office de la Recherche Scientifique et Technique Outre-Mer ( ORSTOM )  seismic stations on Espiritu Santo Island and Efate Island – and 15-miles down at the bottom of the ultra deep sea where the epicenter was believed located.

Rainforest covered Vanuatu Island is positioned in front of the d’Entrecasteaux collision zone of geographic plates, beneath the ulta deep sea, between the North Aoba Basin and South Aoba Basin and along a fracture ( Geographic Reference coordinate: N50E ) transverse to the volcanic arc Ring of Fire.

The December 25, 2010 earthquake registered a 7.8 Richter scale, however later the U.S. Geological Survey ( USGS ) ’officially downgraded’ that same earthquake to a 7.3 Richter scale measurement reported to the public by the Associated Press ( AP ).

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 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.

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.

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.

Title: Petrology and geochemistry of the lower ocean crust formed at the East Pacific Rise and exposed at Hess Deep: A synthesis and new results

Publication: Geochemistry, Geophysics, Geosystems, Volume 3, Issue 11, pp. 1, CiteID 8604, DOI 10.1029/2001GC000230 (GGG Homepage)

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.

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 ).

Title: The Aurora volcanic field, California-Nevada: oxygen fugacity constraints on the development of andesitic magma

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.
