Cerros Amarillos: An alteration porphyry type system, Upper Miocene, Cordillera Principal, Mendoza

In the Cerros Amarillos area, Cordillera Principal of Mendoza province, Argentina (35°S, 70°W) it crops out an alteration zone which is spatially linked to volcanics of Upper Miocene age. It is characterized by early potassic alteration with a paragenesis of biotite-magnetite. It is overprinted by a...
