粤北某铀矿勘查区深部铀矿找矿潜力分析

基于大比例尺区域地质调查工作,在粤北某铀矿勘查区通过分量化探和土壤氡气测量开展深部铀矿找矿工作。已知的隐伏铀矿区测量结果表明,铀矿赋存在断裂之中,在含矿断裂上方形成U的分量化探异常和土壤氡气异常;在该异常区内,同时伴随W、Be、Ba、Mo、Li、Ni的分量化探异常。综合分析分量化探和土壤氡气资料,勘查区内北北东向F_2、F_1处的分量化探和土壤氡气异常具备已知隐伏铀矿区的全部异常特征,推测该处异常具有较大的深部找矿前景,进一步的钻探工作正在进行中。

Analysis of prospecting potential of deep uranium deposits in an uranium exploration area of north Guangdong Province

On the basis of large-scale regional geological surveys, component geochemical exploration and soil radon measurement have been carried out to search for deep deposits in an uranium mine in north Guangdong Province. The results of known concealed uranium deposits indicate that these deposits exist in faults, above which anomalies of U component geochemical exploration and soil radon were observed. In this anomaly area, there also exist component geochemical anomalies of W,Be,Ba,Mo,Li and Ni.Comprehensive analysis of component geochemical exploration and soil radon data suggest that characteristics of these anomalies associated with the known concealed uranium deposits are present in the NNE-trending faults F2 and F1 in the exploration area. It is speculated that these places should have a major prospect for ore-search at depth. Further drilling work to validate this inference is under way.
