Vein-type gold deposit, hosted in a WNW-striking shear zone in Ordovician andesite and basalt, that is a subsidiary structure of the Altunshan strike-slip fault system. The mineralization consists of a surface to near-surface gold-bearing gossan zone composed of jarosite, gypsum and relict quartz, and three types of primary ore, (1) early-stage quartz-sericite-pyrite ores in stockworks, (2) early-stage disseminated ore, and (3) late-stage quartz-calcite-sulphide veins. The ore system is characterized by variable degrees of potassic and silicic alteration.
