摘　　要：在粤北某花岗岩铀矿勘查区开展了地气测量探测隐伏铀矿的试验研究。通过对勘查区4号和19号勘探线的快速地气取样,获取了U、Cu、Pb、Zn、Mn、Sr和稀土等38种元素信息。利用聚类分析、Pearson相关性分析以及稀土配分、Eu异常判断等方法对矿体的地气异常进行了研究,结果表明,U、Mn、Sr、Zn等地气异常在矿体上方或矿体边缘位置有不同程度的显示;U异常与Mn、Sr、Eu、Cu、Pb、Zn、Ho有较好的相关性;矿体上方地气异常区具有相似的稀土配分模式和负Eu异常。这些特征可以作为判定隐伏铀矿矿致地气异常的依据。The experimental study of geogas was carried out in granite uranium exploration area of northern Guangdong. Through quickly sampling of No. 4 and No. 19 exploration line in exploration District, the authors acquired information from the 38 elements of U, Cu, Pb, Zn, Mn, St, REE, summarized exceptional characteristics through cluster analysis, pearson relativity, LREE partition, Eu exceptional judge and so on. The results show that geogas anomalies of U, Mn, Sr, Zn have different display above the ore body or border position. Anomalies of U have good correlation with Mn, Sr, Eu, Cu, Pb, Zn, Ho. Geogas anomaly area above the ore body have similar REE patterns and negative Eu anomalies. These characteristics can be used to judge mineralize geogas abnormal of concealed uranlum.
