Geology and Metallogenesis of the Nanlongwangmiao Gold Deposit in Qingyuan, Liaoning Province

摘要

    

///The Nanlongwangmiao gold deposit in Liaoning Province, tectonically located in the Archean Fushun-Qingyuan greenstone belt, occurs in the Hongtoushan volcanic-clastic rock formation of Anshan group, with wallrocks of magnetite amphibolite quartzite, biotite granulite and leucogranulitite. The orebodies, commonly in small scale, are controlled by the ductile shear zone, presented in lenticular, veined and layered shapes as disseminated-veinlet Au-bearing pyrite ores and Au-bearing pyrite quartz veins. The Au appears as native gold. The S isotopes are derived from the deep. The Pb isotopes show that the ore matters are from the greenstone. The H and O isotopes indicate that the ore-forming fluid is the mixture of metamorphic water and meteoric water. It is concluded that the Nanlongwangmiao gold deposit is of stratabound ductile shear zone-controlled metamorphic-meteoric mixed hydrothermal type.
