摘要
程家山金矿区位于大崎山穹窿北缘,矿体呈透镜体状赋存于近南北向断裂构造中,矿体在走向上具有尖灭再现、膨胀狭缩的特征,在平面上具等距性。断裂构造膨大部位围岩蚀变越强,Au品位越高。矿床成因类型属于中低温热液脉型金矿床,工业类型属于构造蚀变岩型金矿床。综合分析表明,程家山金矿区地表近南北向断裂构造中依然具有寻找矿体的潜力,Ⅰ-2号矿体深部依然具有寻找工业矿体的可能性。
Chengjiashan Gold District is located in the northern margin of Daqishan dome.The gold ore body is presented in a lenticular form in a near SN fault.The gold ore body has the characteristics of pinching-out and reappearance,swelling and shrinking and is distributed in equal distance in plane.The stronger the surrounding rock altera-tion in the swelling parts of fault structure is,the higher the Au grade.The genesis of the gold deposit is medium-low-temperature hydrothermal vein type gold deposit.The industrial type is structural alteration rock type gold deposit.Comprehensive analysis shows that the near SN fault of Chengjiashan Gold District still bears good potentials of finding gold ore body,and deep inⅠ-2 ore body may still exist industrial ore bodies.
