中文摘要:
      刘家峡金矿床位于南秦岭山阳矿集区东部,矿床产出于近东西向镇安-板岩镇大断裂南侧的NE、NNE和NW向次级构造带内。矿体主要赋存于泥盆系西岔河组层中,呈透镜状、脉状;矿体形态、产状严格受断裂带控制,断裂构造发育密集处为富厚矿体赋存的有利部位,近矿围岩蚀变较强,主要有黄铁矿化、褐铁矿化、硅化。该矿床为构造蚀变岩型金矿床估算金资源量5余吨。文章通过总结刘家峡金矿床的地质特征和找矿标志,分析矿床成因,评价了刘家峡金矿的成矿潜力,为该区的进一步找矿工作提供思路。
英文摘要:
      The Liujiaxia gold deposit is located in the east of Shanyang ore concentration area, South Qinling Mountains. The deposit is located in the NE, NNE and NW trending secondary structural belts near the south side of the East-West Zhenan banyanzhen fault. The ore body mainly occurs in the strata of Xichahe formation of Devonian system, in the form of lens and vein; the shape and occurrence of the ore body are strictly controlled by the fault zone, and the densely developed fracture structure is the favorable place for the occurrence of the rich thick ore body. The wall rock near the ore has strong alteration, mainly including pyritization, limonitization and silicification. The deposit is a structural altered rock type gold deposit. This paper summarizes the geological characteristics and prospecting criteria of Liujiaxia gold deposit, analyzes the genesis of the deposit, evaluates the metallogenic potential of Liujiaxia gold deposit, and provides ideas for further prospecting in this area.
