摘　　要：通过对夏家店金钒矿床地质特征、矿体赋存特征的分析和研究,得出该区主要的控矿因素为地层和构造。地层因素中,寒武系水沟口组黑色岩系为主要的控矿地层。构造因素中,镇-板断裂为夏家店金矿的主要导矿构造,次级断裂(F4、F5)为主要的储矿构造。在此基础上,提出了该区金钒矿的找矿靶区,即以夏家店金钒矿床为中心,夏家店东部构造急剧减弱,但地层完整,应是钒矿成矿有利地段。夏家店至东侧甘沟应开展金矿床的找矿预测。而在夏家店以西至冷水沟段,地层缺失较多,构造变形虽然强烈,但提供形成金、钒矿床的地层建造物质基础差,导致沉积型钒矿规模小,改造型金矿床的矿化强度不理想,找矿难度较大。Based on the study of regional geology,mining geology and ore bod characteristics of the Xiajiadian Gold -Vanadium Ore,we know that the main ore-controlling factors in this area is the formation and the geological structure.About formation factors,the black rock series of Shui Gou-kou group of the Cambrian is the main ore-controlling strata;about structural factors,the Zhen＇an-Banqiao Fault（F1） is the main guide construction,It＇s secondary tectonic（F4 and F5） is the main reservoir host structures.On this basis,we propose the favorable prospecting regions,that is the regions east to Xiajiadian Gold-Vanadium Ore,the simple structure but the integrity stratigraphic,should be the favorable areas for the vanadium resources;and between the Xiajiadian and the Gan Valley,should be the favorable areas for the gold resources.
