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

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...
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. ...
