The Somún Curá Magmatic Province, in north central Argentine Patagonia, is characterized by a series of events with a temporal distribution that most authors group into plateau and post-plateau volcanism. The post-plateau events built up the most important volcanic edifices which correspond to sierras showing lithological and eruptive complexity according to which different Volcanic Complexes were defined. The latter are, in turn, integrated into the Quiñelaf Superunit. In the northeastern of the basaltic plateau, the Alta Sierra de Somún Curá Volcanic Complex (ASSVC) was emplaced, representing the smaller volcanic complex.
