Metallogeny of the Paramillos de Uspallata Pb–Zn–Ag vein deposit in the Cuyo Rift Basin, Argentina
The Paramillos de Uspallata deposit, previously considered as genetically linked to a Miocene porphyry deposit, is located in the Mesozoic Cuyo Basin, which was formed during the beginning of the break-up of Gondwana. In the present study, both previous information and new geological, mineralogical,...
