Geological Feature and Prospecting Indicator of Dongyaozhuang Greenstone Belt-Type Gold Deposit in Shanxi Province

摘要

Dongyaozhuang greenstone belt-type gold deposit occurs in Wutai greenstone belt. Host strata are upper Archaeozoic erathem Wutai Group Hongmenyan formation greenschist, presenting obvious characteristic of layer-controlled. Deposit consists of I, II, III orebodies. The orebodies are lamellar, vein, extending to NE. The host rocks are sericite albite schist, sericite quartz schist, sericite albite chlorite schist and metadiabase dyke and have experienced intensive pyritization, silicification and carbonatization. The wall rock alteration and development is mainly silicification, sericitization, chloritization, carbonatation and pyritization, from inside to outside presenting zonation. Deposit has obvious prospecting indicator of geology, geophysics and geochemistry.
