“…Nb/Zr and Nb/Y ratios and REE patterns of the basalts included in this study indicate low degrees of partial melting of an enriched mantle source, as previously reported for basalts from other parts of Patagonia by Stern et al (1990), Kay et al (2004) and Massaferro et al (2006). All the studied samples show depletion of HREE compared to LREE, and Ti/Y N ratios are >1 in the three areas.…”

“…Tertiary shortening is particularly well documented by both foreland basin and wedge‐top basin synorogenic deposits, which preserve progressive unconformities and effectively record depocenter migration during the Miocene [ Ramos et al ., ; Orts et al ., ; Bilmes et al ., ; Echaurren et al ., ]. The overlying flat‐lying Pliocene‐Pleistocene volcanics, classifying as alkali basalts, basanites, and trachybasalts, indicate a within‐plate environment that differs from previous Andean arc‐magmatic rocks [ Massaferro et al ., ].…”

“…They proposed that the degree of partial melting and the amount of slab-derived component decrease eastward away from the VA. Varekamp et al (2010) identified an EM-1-like signature in the young, olivine-rich basalts from the Loncopué Graben in the BA, possibly reflecting subcontinental lithospheric mantle. In the Crater Basalt Volcanic Field (BA), volcanic rocks from monogenetic centers were attributed to decompression melting of a garnet lherzolite asthenospheric mantle (Massaferro et al, 2006, Pécskay et al, 2007.…”
