| 中文摘要: |
| 洪水河口金矿位于柴达木盆地南缘,东昆仑(造山带)Fe-Pb-Zn-Cu-Co-Au-W-Sn-石棉成矿带上。目前金矿储量达4.88 t,金平均品位4.21 g/t。依据1∶2.5万地球化学测量资料,结合地质特征,对洪水河口地区7种元素的分布、相关性、组合异常等特征进行了分析研究,圈出1处金综合异常,通过对异常初步查证,圈定出1条大型金矿化蚀变带,1条金矿化体,说明1∶2.5万地球化学测量可以在该区发挥很好的找矿指导作用,同时建立了该区地质地球化学找矿模型,指出了下一步找矿方向。 |
| 英文摘要: |
| The Hongshuihekou gold deposit is located in the southern margin of the Qaidam Basin,and the Fe-Pb-Zn-Cu-Co-Au-W-Sn-asbestos metallogenic belt of the East Kunlun (orogenic belt).According to 1∶25,000 geochemical survey data,and combining the geological features,Research the distribution,correlation,combination anomaly of seven elements in the Hongshuihekou area.Circle 1 gold synthesis anomaly,Through the preliminary verification,A large gold alteration zone have been identified in the mining area,and one gold mineralized bodies.This indicates that 1∶25,000 geochemical survey can play a good guiding role in prospecting in this area,and the geological and geochemical prospecting model is established,The next prospecting direction is pointed out. |
