摘　　要：为解决鄂尔多斯盆地厚层覆盖区找矿难题,运用地电化学法在鄂尔多斯盆地东胜地区进行了找矿预测研究。地电化学法测得隐伏铀矿体上方的地电提取异常。由此建立一套适用于在鄂尔多斯盆地东胜地区寻找隐伏铀矿床的勘查集成组合技术,并应用于该区1200km2范围内的找矿预测。结果在预测区内找到了6个具有找矿前景综合异常靶区,为在鄂尔多斯盆地东胜地区厚覆盖区的找矿指明了方向。In order to solve the problem of searching ore deposits,which are covered by thick strata,in the Dongsheng area of the Ordos sedimentary basin,the geo-electrochemical method was applied for prospecting of concealed uranium deposits. Through the analysis of prospecting feasibility test,we found that geo-electrochemical measurement has an obvious electro-extraction anomaly above the known concealed uranium ore bodies,which suggests that geo-electrochemical method is effective for searching concealed uranium deposits in the Dongsheng area of the Ordos basin. A set of technique was established on the basis of combining geo-electrochemical anomalies and geological conditions of the study area and metallogenic model and was applied to searching concealed uranium deposits in a scope of 1200 km2 in the Dongsheng area of the Ordos basin. Besides marked 6 prospecting targets,we made suggestions on further exploration of concealed uranium deposits in the Dongsheng area of the Ordos basin.
