| 中文摘要:为了快速查明古宁浑迪地区砂岩型铀矿的有利成矿地段，并为钻探验证工程的部署提供依据，研究过程中采用了铀及伴生元素活动态分量探测地球化学勘查方法。通过系统采集样品和铀、钼、硒分量提取及测试，认为吸附态铀及伴生元素分量探测更适用于本地区砂岩型铀成矿有利地段的筛选。经钻探工程验证，绝大部分地表铀分量异常均与深部成矿目的层中的铀矿化或铀异常相对应，证实了铀及伴生元素活动态分量探测是适用于寻找隐伏砂岩型铀矿床的有效方法，尤其适用于古河道型砂岩铀矿的找矿勘查。 |

| Abstract:In order to realize rapid detection of favorable areas for sandstone type uranium deposits and provide effective and reliable basis for arrangement of drilling projects in Guninghundi area, the authors adopted mobile forms of elements and techniques for detecting uranium and other associated elements in the course of investigation. Based on systematic sampling, extracting and testing of mobile forms of elements such as uranium, molybdenum and selenium, it is concluded that adsorptive uranium and other associated mobile forms of elements are especially suitable for delineating favorable districts in search for sandstone type uranium deposits of this area. Drilling work also indicates that surface uranium anomalies are mostly related to uranium mineralization and uranium anomalies in deep ore-forming target strata, and that the mobile forms of elements serve as an effective means for detecting hidden uranium deposits in geochemical exploration, especially in the exploration of fossil valley type uranium deposits. |
