Resumen:
Alkali basalts of Pliocene ? Quaternary age occur along Patagonia in Argentina. Therocks have typical intraplate OIB-like geochemical characteristic. Volcanic activity in this back-arc region is related to subduction of Nazca and Antarctic plates beneath South American Plate.The Cerro Chenque occurrence of peridotitic, pyroxenitic and gabbroic xenoliths hasbeen discovered during 2013 field works in Patagonia. The presented results are based on preliminary study of two protogranular/porphyroclastic spinel lherzolite xenolith.
