土壤元素地球化学测量在樟岭地段铀-多金属矿勘查中的应用

Application of soil element geochemical survey in the exploration of uranium-polymetallic deposits in Zhangling section

通过对樟岭地段开展1∶10000土壤元素地球化学测量及异常查证工作,基本查明了区内目标地段土壤中Li、W、Cu、As、Zn、Rb、Sn、Bi、Nb、Ta、Pb、Th和U共13种元素的含量特征以及元素分布范围和组合特征。综合分析该区成矿地质条件和地球化学信息,认为该区主要成矿元素为U、Pb和Zn,3种元素分异性强、集散性明显、相关性好,并圈定了地球化学综合异常3处。通过对樟岭地段土壤元素地球化学特征及成矿地质条件的深入分析,预测,为区内下一步找矿工作提供了找矿方向和有利预测靶区。

The 1∶10000 soil element geochemical survey and anomaly verification were carried out in Qingzhangshan area of northern Guangdong province.The content of 13 elements Li,W,Cu,As,Zn,Rb,Sn,Bi,Nb,Ta,Pb,Th and U,as well as their distribution and combination characteristics,were basically identified in the target sector.By comprehensive analysis of the geological conditions and geochemical information,the main mineralzed elements in this area were U,Pb and Zn,which have strong differentiation,obvious distribution and good correlation.Three valuable geochemical anomalies were delineated.Through the analysis of soil element geochemical survey and metallogenic geological conditions in Zhangling section,the metallogenic propects were predicted,which provides the prospecting direction and favorable target for the next prospecting work in the area.
