Geologic and tectonic setting of Deseado Massif epithermal

Abstract Middle Late Jurassic bimodal volcanism, typical of a retroarc setting, developed during widespread extensional tectonism within the Deseado Massif, southern Argentina. This geologic environment led to the formation of numerous low sulfidation epithermal deposits that are spatially and temporally related to the volcanic activity.
