西宁盆地包马庄地区砂岩型铀矿综合地球物理响应特征及找矿预测
Integrated Geophysical Response Characteristics and Prospects Prediction for Sandstone-type Uranium Deposit of Baomazhuang Area in Xining Basin
摘要
Abstract
Cenozoic strata are widely developed in Xining basin,which provides beneficial geological condition for sandstone-type uranium mineralization.To study geophysical characteristic of target layer and locate the deep buried uranium ore bodies,this article focus on Early Cretaceous Hekou Group.Based on the collected geological and geophysical data,we analyzed geology-geophysics features of target layer with activated carbon measurement and CSAMT method,to study how these features affect uranium deposition and serve the forecast of prospect.The result shows that abnormal of radon concentration can reveal the uranium mineralization in deep buried sandstone bodies with the moderate or low resistivity layer indicator.Combining the geological and geophysical features,we can depict the space shape of favorable uranium-bearing sandstone bodies,which contribute to forecast and delineate prospecting target area and provide references for drill hole verification.关键词
