| Abstract: | The Mianshawa gold deposit is typical one hosted in contact zone between intermediate acid intrusive rocks and surrounding rocks in the Sichuan province, which is closely related to ductile shear belt. The gold mineralization is accompanied with silication, sericitization and chloritization. The main mineral paragenesis is quartz, pyrite, galena, chalcopyrite, tetrahedrite, sphalerite, native gold, sericite and dolomite. The element association is gold,copper, silver, lead, zinc, arsenic, antimony and bismuth. The deposit was formed under the lower middle temperature and pressure by the underground hot saline water recharged by meteoric water during Himalayan orogeny. |
