陕西山阳县夏家店金矿床大地构造位置位于南秦岭造山带印支褶皱带凤县–镇安束的东部，武当隆起西北缘，镇板断裂南侧。矿床类型属构造蚀变岩型。金矿体主要赋存于寒武系水沟口组地层的碳硅质板岩和泥盆系西岔河组地层砂砾岩中，严格受北东向、近东西向断裂控制，构造叠加部位易富集成为矿囊、矿柱。金矿体走向上呈等间距、扁豆状分布，显示成群、成带出现规律。通过对矿床地质特征、矿体特征及分布规律、控矿因素的综合研究分析，认为夏家店矿床找矿潜力巨大。在此基础上进行了找矿靶区预测，为实现找矿突破提供了理论支撑。 The tectonic position of the Xiajiadian gold deposit in Shanyang County is located in the eastern part of Fengxian-Zhen’an Bund, the northwestern margin of Wudang uplift, and the south of Zhenpan fault in the Indosinian fold belt of South Qinling orogenic belt. The deposit type is tectonic alteration rock type. The gold deposits mainly occur in the Carboniferous siliceous slate of the Cambrian Shuigoukou Formation and the strata of the Xichahe Formation in the Devonian system. They are strictly controlled by the NE trending and the EW trending faults. The superposition part of structures is easy to become mineral bag and pillar. The gold ore bodies are equidistant, lenticular-like, showing flocks and bands. Based on the comprehensive analysis of the geological features, ore body characteristics and distribution, ore-controlling factors, it is concluded that Xiajiadian deposit has a great prospecting potential. On this basis, the prospecting target is predicted, which provides a theoretical support for the prospecting breakthrough.
