综合物化探方法在坦桑尼亚卡尹泽金矿区勘查中的应用

Application of the integrated geophysical and geochemical techniques to prospecting of Kayenzi gold field in Tanzania

坦桑尼亚卡尹泽金矿区位于坦桑尼亚卡哈马绿岩带,是坦桑尼亚金矿重要成矿区。通过开展地面高精度磁法测量、土壤地球化学测量和激电中梯测量相结合的综合物化探方法研究,分析了物化探异常特征,建立了卡尹泽金矿区物化探综合找矿评价标志,为矿区下一步找矿工作指明了方向。后经工程查证,在物化探异常区内发现了金矿体,综合物化探方法在卡尹泽金矿区找矿效果明显。

Kayenzi Gold District is located in the greenstone belt of Kahama which is an important gold mineralization belt in Tanzania. By using the integrated geophysical and geochemical techniques,such as high-precision gound magnetic survey,geochemical soil survey and IP intermediate gradient survey,the paper summarizes the regional geological characteristics and the comprehensive anomalous characteristics of the geophysical and geochemical prospecting The geophysical and geochemical prospecting criteria or indicators of the Kayenzi Gold District are established. The research points out the prospecting direction of future exploration work. By engineering verification for geophysical and geochemical anomaly areas,and the gold orebodies have been found,showing that the integrated geophysical and geochemical is notably effective in Kayenzi gold district.
