Geochemical variations in the Quaternary Andean back-arc volcanism, southern Mendoza, Argentina
The Payenia Basaltic Province (PBP) is located 450. km east of the Chile-Peru trench in central west Argentina, behind the Andean arc front, constituting the back-arc. In order to evaluate the influence of the subducting slab as well as the magmatic source of this region, two volcanic fields located at comparable distance to the trench, having abundant basaltic products and similar eruptive timeframes were chosen. The Llancanelo (LLVF) and the Payún Matrú (PMVF) volcanic fields are part of the...[Show more]
