摘　　要：湖南锡田地区位于著名的南岭钨锡铅锌多金属成矿带湖南段,近年来显示巨大找矿前景,随着找矿勘探工作的深入,因第四系覆盖找矿难度增加,覆盖区有效靶区优选方法迫在眉睫。地气测量经多年来不懈研究,初步解决了捕集介质本底影响、野外操作系统误差等问题,结合其他方法,在湖南锡田地区优选锡钨矿靶区应用中发现地下190 m深钨矿体。笔者认为,地气测量可作为深部寻找隐伏矿的有效化探方法,将在覆盖区找矿靶区优选中发挥巨大作用,推动隐伏矿的勘查工作。Xitian area on Hunan province is located in the famous human Naning tungsten-tin polymetallic metallogenic belt and that shows huge prospecting exploration in recent years.Because of the Quatemary cover prospecting difficulty in crease,the coverage effective optimization methods is imminent with the deepening of the exploration work.Geogas survey prelimary solved the capture medium background influence,field operation system error and other issues by the unremitting research for many years,In combine with other m ethods,Xitian area on Hunan province optimization tungsten target applications found in the 190 meter deep underground tungsten ore body.The author thinks that the geogas survey can be used as a deep search for concealed deposies and effective geochemical exploration methods,in the coverage area of prospecting target areas selection play a huge role,promote the explorations of concealed deposites.
