综合地物化找矿方法在内蒙古西尼乌苏铜金矿区的应用

Application of integrated technology of geology,geophysics and geochemistry to prospecting at the Xiniwusu Cu-Au deposit,Inner Mongolia

西尼乌苏铜金矿区位于内蒙古阿拉善盟,该矿区激电异常呈低阻高极化特征;测深拟断面显示,深部异常有增大趋势;土壤测量在矿区内圈定多处综合异常,Cu、Au等元素异常规模大,强度高。该矿区物、化探异常套合较好,对应地表岩石硅化、孔雀石化等蚀变较强,据此建立了西尼乌苏铜金矿区的找矿标志,经槽探工程验证,矿区内圈定多条铜矿体及金矿体,找矿效果良好。该区的综合地物化找矿方法为该地区找矿勘查提供了范例。

Located in Alxa League,Inner Mongolia,Soil geochemical and geophysical methods were employed to investigate the comprehensive anomalies of the Xiniwusu Cu-Au deposit.Low resistivity and high IP anomalies with the geochemical anomalies of Cu Au of large scales with high intensity in the Xiniwusu CuAu deposit,and the deep anomaly tends to increase.The geophysical and geochemical anomalies in the mining area are well combined,and the corresponding surface rock silicification,malachitization and other alterations are strong.Combined with geological,geophysical methods and soil geochemical characteristics of the Xiniwusu Cu-Au deposit,propose a comprehensive prospecting model in the search for new orebodies.The subsequent geological verification shows a good prospecting effect with several Cu-Au ore bodies.This integrated application of geology,geophysics and geochemistry provides an examples for this area.
