摘　　要：基于地气法对铀矿勘查区地面γ测量U含量异常的解析。通过地面γ能谱测量的U含量数据划分出三个U含量异常区,分别在三个异常区分析了U/Th、U/K和活化U。与此同时,由ICP-MS获得的地气元素数据,找出各元素含量的异常区,然后在γ能谱测量的各个U含量异常区域中找出含量异常的地气元素,并将异常区中的地气异常元素与地气中U进行相关分析。最终确定了引起各个γ能谱测量的U含量异常区域的原因。Analysising reason of abnormal content of uranium that was measured by gama-ray spectrometer in an uranium exploration area is based on geogas. Dividing into three abnomal areas depend on content data of uranium that gaining from gama-ray spectrometer and analysising U/Th, U/K and active uranium. At the same time, gaining data of geogas sample from ICP-MS, and abtaining abnomal area of every element that contained in geogas, then finding out abnormal elements in geogas in the region of abnormal content of uranium that was measured by gamaray spectrometer, and analysising relationship between uranium and other abnormal elements in geogas by correlation analysis. Finally, determining the reason that cause abnormal content of uranium that was measured by gama-ray spectrometer.
