Abstract
[ES] En el SO de la Provincia del Chubut (República Argentina) se han reconocido depósitos hidrotermales Au-Ag y metales asociados (Cu, Pb, Zn). Estas mineralizaciones aparecen en filones de cuarzo asociadas a adularia-sericita y alteración clorítica relacionadas especialmente a rocas subvolcánicas cretácicas Las características geológicas, estructurales y mineralógicas indican que estas mineralizaciones son de tipo adularia-sericita o de baja sulfuración.
[EN] Epithermal Au-Ag occurrences associated with base metals (Cu, Pb y Zn) have been identified in the south-west Chubut Province, Argentine. Mineralizatión is hosted by quartz vein - type structures, wich are associated with adularía - sericitic and chloritic alteration, mainly related to cretacic subvolcanic rocks. Geological, structural and mineralogical features, suggest an adularla - sericite or low sulphidation type deposit.
