摘　　要：以我国南岭矿集区的两个具有典型意义的区域:湖南黄沙坪和广西大厂,开展了地气场研究,目的是寻找地气场与矿体的关联规律。通过系统分析,研究了矿致地气异常的特征,结果表明,通过地气异常中成分比例的统计,可以判定隐伏矿体是什么成分的矿体;地气异常的元素组合中,可以提取围岩和岩浆活动的一些信息。A study of the geogas field was carried out in Huangshaping of Hunan Province and Dachang of Guangxi, two areas with typical significance in Nanling ore concentration area. The aim is to find the relationship between the geogas field and the ore body. Through a systematic analysis, the characteristics of ore-induced geogas anomalies were studied. The results show that the statistics of component proportions in the geogas anomaly can be used to judge the components of the concealed ore body and, what is more, some information about surrounding rocks and magmatic activities can be extracted according to the element association of the geogas anomaly.
