Subvolcanic contact metasomatism at El Laco Volcanic Complex, Central Andes
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2010)
The advocate ophiolite mantle, Baie Verte, Newfoundland: Regional correlations and evidence for metasomatism
(National Research Council Canada-NRC Research Press, 2010-03)
Mantle rocks of the Advocate ophiolite near Flatwater Pond (Baie Verte, Newfoundland) are dominated by harzburgite tectonites, which are extensively converted to listvenite along the Baie Verte Road fault and represent a ...
Depleted lithosphere from the mantle wedge beneath Tres Lagos, southern Patagonia, Argentina
(Elsevier Science, 2007-03-22)
Anhydrous spinel lherzolite and harzburgite xenoliths from Tres Lagos, situated inboard of the Volcanic Arc Gap (VAG) in southernmost Patagonia, are samples of a depleted lithospheric mantle and can be divided into two ...
Origin of red beds and paleosols in the Palaeoproterozoic Transvaal and Olifansthoek Supergroups of South Africa: provenance versus metasomatic controls
(Wiley-Blackwell, 2018-01-01)
The Palaeoproterozoic Transvaal and Olifantshoek Supergroups of South Africa contain some of the earliest hematite-rich sedimentary rocks (red-beds) and paleosols on record. The origin of these rocks has been variously ...
Experimental constraints on adakitic metasomatism of mantle wedge peridotites below Patagonia
(2015)
We performed a series of high-pressure (1.5
GPa) and high-temperature (1000-1300 ºC) experiments to
investigate the geochemical imprints of adakitic
metasomatism on mantle wedge peridotite. Reaction
couples were prepared ...
Experimental constraints on metasomatism of mantle wedge peridotites by hybridized adakitic melts
(2018)
In this study, a series of high-pressure (1.5 GPa) and high-temperature (1000–1300 °C) experiments were performed to investigate the petrological imprints of adakitic metasomatism on mantle wedge peridotites. Reaction ...

Metasomatism and Melting in Carbonated Peridotite Xenoliths from the Mantle Wedge: The Gobernador Gregores Case (Southern Patagonia)
(Oxford University Press, 2001-01)
Spinel-facies mantle xenoliths occur in a diatreme cutting through the Neogene Southern Patagonia Plateau at Gobernador Gregores (Santa Cruz Province, Argentina). This plateau is in a back-arc position with respect to the ...
