摘　　要：大构园沟钒矿是近年来陕西境内新发现的中型钒矿床,属于南秦岭多金属成矿带黑色岩系中带成矿的一部分。笔者从成矿地质环境、矿床地质特征、成矿作用综合信息研究入手,对大构园沟钒矿床成因进行了分析,认为寒武系水沟口组是区内钒、金的主要赋矿层位,碳泥质板岩、含碳质石英砂岩(炭硅质岩)是赋矿的有利岩性,也是找矿的直接标志。矿床成因属有机质参与的海底热水沉积(改造)型矿床。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.
