Discussions on Geological Characteristics and Ore Genesis of Dagouyuangou Vanadium Deposit in Ningshan County,Shaanxi Province

Dagouyuangou vanadium mine is a newly discovered middle-scale vanadium deposit in Shaanxi Province, that belongs to mineralization of black rock series in middle belt of south Qinling multi-metals ore-forming zone. On the basis of researching metallogenic geology environment, deposit geological feature and comprehensive information of mineralization, the author analyzed the metallogenesis of the deposit and considered that Cambrian Shuigoukou Formation is main ore-hosted position of vanadium and gold. Carbonaceous argillite and carbon-bearing quartzose sandstone or carbonaceous silicalite are favorable host rocks as well as direct signs for exploration. The genesis of this vanadium deposit belongs to organic matter participated seafloor hydrothermal sedimentary reformation deposit.
