Study on Gold Occurrence in Zhaishang Large Type Gold Deposit in West Qinling

Use of micro-testing technology,found gold occurrence in zhangshang gold deposit in three ways: First,gold was micro inclusions or were isomorphous substitution of atoms existed in the lattice of gold-gold minerals were;two is a natural gold occurrence in quartz,kaolinite and other debris between the gold particles formed between grains;Third,the existence of natural quartz gold endowed was calcite barite veins in the fissures.From the Gold Occurrence of the Causes,combined gold deposit tectonic evolution of ore formation,lithology,petrography,we believe that the deposit type gold deposit should be deposited metamorphic-tectonic hydrothermal superposition type gold deposit.
