THE GEOLOGY OF JOSEPHINITE IN THE JOSEPHINE PERIDOTITE, SOUTHWEST OREGON
Metal alloy mineral oxide and silicate sulphide andradite garnet petrochemical base rock
2014/10/22
Josephinite, a mineral assemblage of native metal alloys, oxides, silicates and sulfides, is found in serpentinized portions of the Josephinie peridotite and as placer nuggets along Josephine Creek. J...
Petrology and geochemistry of the back-arc lithospheric mantle beneath eastern Payunia (La Pampa, Argentina): Evidence from Agua Poca peridotite xenoliths
gmantle xenoliths fractional melting mantle metasomatism depleted mantle reservoir Argentinatagonia
2017/4/11
This paper presents the results of new petrochemical studies carried out on mantle xenoliths hosted in Pleistocene
basaltic rocks from the Agua Poca volcano in central-western Argentina. Mantle xenol...
Hydrous, Low-carbon Melting of Garnet Peridotite
Hydrous Low-carbon Melting Garnet Peridotite
2014/4/8
The presence of volatile species in the Earth’s upper mantle drives
the formation of low-degree melts at pressures and temperatures
at which volatile-free mantle rocks would be subsolidus. The two
...
Could peridotite hydration reactions have provided a contributory driving force for Cenozoic uplift and accelerated subsidence along the margins of the North Atlantic and Labrador Sea?
peridotite hydration reactions contributory driving force Cenozoic uplift accelerated subsidence
2009/12/2
This study evaluates the hypothesis that peridotite hydration reactions (e.g.serpentinisation) at the landward termination of transform fracture zones provide a contributory driving force for coupled ...
Constraints on the evolutionary history of aluminous mafic rocks in the Ronda peridotite massif (Spain) from trace-element compositions of clinopyroxene and garnet
trace-element clinopyroxene garnet eclogite Ronda granulite
2017/8/9
Multiple trace-element compositions of clinopyroxene and garnet in aluminous mafic layers (±corundum and/or sapphirine) alternating with peridotites from the Ronda massif, Spain, were determined by an...

Calculation of Peridotite Partial Melting from Thermodynamic Models of Minerals and Melts. II. Isobaric Variations in Melts near the Solidus and owing to Variable Source Composition
Thermodynamic Models Melts near the Solidus
2014/4/8
We examine several issues related to peridotite partial melting by composition (Na2O decreases, CaO/Al2O3
increases) are similar to
performing thermodynamic calculations using the MELTS algorithm. t...
FLOW-LAYERING IN ALPINE PERIDOTITE-GABBRO COMPLEXES
FLOW-LAYERING IN ALPINE PERIDOTITE-GABBRO COMPLEXES
2014/4/8
Compositional layering in gabbro and peridotite may originate in several ways; in alpine complexes most of it is believed to be flow layering. Disruption of relict primary features formed by crystal s...
CRYSTALLIZATION OF LEUCITE-NEPHELINE-SANIDINE IN BASIC DIFFERENTIATES FROM A PERIDOTITE-DUNITE MASS IN SALEM, MADRAS STATE, INDIA
CRYSTALLIZATION LEUCITE-NEPHELINE-SANIDINE IN BASIC DIFFERENTIATES A PERIDOTITE-DUNITE MASS IN SALEM MADRAS STATE INDIA
2014/4/8
The potassic rocks of Salem occur as dikes and sheets within or marginal to a dunite-peridotite mass that has intruded into Archean Peninsular gneisses, charnockite series, pyroxenites and dolerites. ...
