安徽黟县水文地球化学特征与铀成矿的关系研究

Study on the relationship between hydrogeochemical features and uranium mineralization in Yixian County,Anhui Province

铀资源是我国重要的能源矿产和战略资源。安徽黟县铀矿属华南地层大区扬子地层区江南地层分区,铀矿化类型主要为碳硅泥岩型,寒武纪荷塘组是区内找矿的主要目标层位。通过在研究区采集水样进行铀和氡含量测定,系统地分析了研究区水文地质条件、放射性水文地球化学特征,并阐述了放射性水文地球化学特征与区内铀矿之间的联系,将研究区划分出6个放射性水化成矿远景预测区,可为该区下一步找矿提供依据。

Uranium resources are important energy minerals and strategic resources in China.The Yixian uranium deposit in Anhui Province belongs to the South China stratigraphic region,the Yangtze stratigraphic region and the Jiangnan stratigraphic division.The uranium mineralization type is mainly carbonate-siliceous-politic rock type.The Cambrian Hetang formation is the main target horizon for uranium prospecting in the area.By collecting water samples in the study area for the determination of uranium content and radon concentration,this paper systematically analyzed the hydrogeological conditions and radioactive hydrogeochemical features of the study area,expounded the relationship between radioactive hydrogeochemical features and uranium deposits in the area,and divided the study area into six radioactive hydration metallogenic prospective areas,which provided reference for further prospecting in this area.
