中文摘要: 西青岗坪金矿床位于豫西熊耳山康山-七里坪成矿带的中部,为典型的构造蚀变岩型金矿床。矿区开展了岩石、土壤地球化学测量、EH4及双频激电测深、可控源音频大地电磁法测量等综合找矿方法,验证工程效果显示,地球化学勘查对于缩小找矿范围、圈定找矿靶区具有非常重要的作用;EH4及双频激电测深对确定断裂带位置、延伸情况具有较好的效果,探测硫化物型金属矿床效果一般;可控源音频大地电磁法测量对指导矿床找矿效果较差。对矿床潜力进行了评价,F1、F6、F7矿脉深部仍具很大的找矿潜力,另外地表及钻孔地球化学工作显示矿区具有形成铅锌多金属矿床的潜力。
Abstract:The Xiqinggangping gold deposit located in the middle of the Kangshan-Qiliping metallogenic belt in Xiongershan, western Henan.It is a typical tectonic altered rock type gold deposit. Comprehensive prospecting methods such as rock and soil geochemical survey, EH4 and dual-frequency IP sounding and controllable source audio magnetotelluric survey have been carried out in the mining area. The verification of engineering results show that geochemical exploration plays a very important role in narrowing the prospecting scope and delineating the prospecting target area, EH4 and dual-frequency IP sounding have a good effect on determining the location and extension of the fault zone, and the effect of detecting sulphide metal deposits is general. The controllable source audio frequency magnetotelluric survey is not effective in guiding the prospecting of ore deposits. The deposit potential is evaluated and there is still great prospecting potential in the deep part of F1, F6 and F7 vein. In addition, the geochemistry of surface and borehole shows that the mining area has the potential to form lead-zinc polymetallic deposits.
