居隆庵铀矿床地温场特征

Geothermal field characteristics of Julong'an uranium deposits

居隆庵铀矿床位于相山铀矿田西部,为我国大型火山岩型铀矿床之一。通过分析大量钻孔测温和水文地质资料,得出地温场与温热水的分布、断裂构造、深大断裂、富大铀矿及铀矿化在空间分布上具—致性。温热水的活动场、水热围岩蚀变和化学成分特征是铀矿找矿的标志。

Julong＇an uranium deposit is located in the western of Xiangshan uranium ore field,it is a large volcanic rock type uranium deposit in China.By analyzing a lot of borehole temperature and hydrogeological data,it is concluded that the spatial distribution of geothermal field was consistant with warm water,fracture structure,deep faults,large rich uranium ore and uranium mineralization.Characteristics of warm water field,the hydrothermal alteration of surrounding rock and chemical composition are indicators for uranium prospecting.
