Geological features and genesis of Mazhuangshan gold deposit in eastern Xinjiang

Mazhuangshan gold deposit is occured in the formation of lower Carboniferous of Baishan Group which composed by neritic littoral facies pyroclastic sedimentary rocks, pyroclastic rocks and carbonate rocks. Its a typical middle sized gold deposit related to volcanic and subvolcanic activity and controlled by subvolcanic intrusive rocks in space and origin. By research mineral deposit geology, fluid inclusion and stable isotope data in detail, the geological features and the genesis of deposit were discussed. Mazhuangshan gold deposit is a meso epithermal deposit which related with acidic intermediate acidic subvolcanic rock in middle Hercynain.
