Such ages confirm the migration of metallogenic activity along with volcanism as the Sierra Madre Occidental migrated southwards since the latest Oligocene and into the Miocene. These deposits are synchronous to andesitic volcanism nearby. In addition, these ages indicate the occurrence of epithermal mineralization prior to the climactic event of ignimbrite flare-up in the Miocene. This makes necessary to refine previous ideas in the metallogeny of southwestern Mexico, which suggested a scenario in which the formation of epithermal and other types of hydrothermal deposits in the region were produced almost exclusively as a result of the early Miocene peak episode of volcanism. 2016 artículo científico 1405-3322 https://www.redalyc.org/articulo.oa?id=94346152012 https://www.redalyc.org/journal/943/94346152012/ https://www.redalyc.org/journal/943/94346152012/html/ https://www.redalyc.org/journal/943/94346152012/94346152012.epub https://www.redalyc.org/journal/943/94346152012/movil en http://www.redalyc.org/revista.oa?id=943 Boletín de la Sociedad Geológica Mexicana application/pdf Sociedad Geológica Mexicana, A.C.
