摘要
The Cuo’a Au deposit is confined to basic meta-volcanic rock of the Upper Triassic Waneng Formation. The orebodies are controlled by NNW-trending and sublongitudinal brittle-ductile shearing-metamorphic zone with the development of wallrock alterations such as pyritization, stibnitization, silieifieation, earbonatization, phlogopitization and graphitization. The Au deposit is tectonic alteration type one. The Gala, Cuo’a and Haizikou ore spots in the north Garze-Litang fracture zone are characterized by strong and widespread geochemical anomalies, showing good prospecting perspective.
