(1984). Among these localities, only two contain garnet-bearing peridotites; Pali Aike located in southern Patagonia (Skewes and Stern, 1979; Douglas et al., 1987; Stern et al., 1989; Kempton et al., 1999) and Prahuaniyeu, located in northern Patagonia (Ntaflos et al., 2001; Bjerg et al., 2009; Gervasoni et al., 2009). Bjerg et al. (2005) suggest that the Patagonian subcontinental lithospheric mantle experienced only minor melt extractions in the garnet peridotite field, while melt extraction was more extensive in the spinel lherzolite field. Furthermore, it was considered that the lithospheric mantle had been moderately to strongly deformed and recrystallized, frequently in the presence of migrating melts (Rivalenti et Petrology and geochemistry of the back-arc lithospheric mantle beneath eastern Payunia (La Pampa, Argentina): Evidence from Agua Poca peridotite xenoliths |
