江西某地区地电化学法寻找隐伏铀矿研究

Electro-geochemical method in search of concealed uranium deposits in a area of Jiangxi province

江西某地区位于华南铀成矿省北部赣杭构造火山岩铀成矿带的相山矿田内,区内成矿严格受构造破碎带控制。利用地电化学法在该区附近同类型已知矿体上方进行了可行性找矿试验,结果在已知矿体上方均测出了清晰的地电化学异常,根据异常特征并结合地质特征建立了地电化学找矿模式。在此基础上,利用该方法在研究区内进行了找矿预测,分别发现3条具有找矿前景的地电化学异常靶区带,为下一步找矿奠定了一定基础。

The area of Jiangxi lies in Xiangshan orefield of volcanic uranium mineralization belt in the north of the northern South China Ganhang structure, where the mineralizationis strictly controlled by the structural fracture zone. Electro - geochemical method was used above the same type known ore body near this area to test the prospecting feasibility, with a result of clear electro - geochemi- cal anomalies above all the known ore bodies. Electro - geochemical prospecting model was built according to the anomalies and geolog- ical features. On this basis, we carried out prospecting forecast using this method in the study area, and found 3 promising exploration target zones with electrochemical anomalies, laying a certain foundation for further exploration.
