Relación entre metamorfismo y mineralización en las rocas básicas y ultrabásicas de Mina Salamanca y los Gateados (provincia de Mendoza, Argentina)

The basic and ultrabasic rocks from Mina Salamanca district and Los Gateados area are metamorphosed in epidote-amphibolite facies, and locally, in greenschist facies conditions. The green chist facies assemblages develop associated to carbonate (±quartz) veins in the amphibolites and to talc+magnesite assemblages in serpentinites. In the latter case, the fluids dissolved a primary, disseminated sulfide mineralization and gave rise to a massive ore along a fault zone in Mina Salamanca district.
