地气测量技术是捕集并测定地下上升气流中痕量金属和非金属元素来揭示较深部地层的信息。文章论述了不同类型隐伏断裂上方地气异常的特征，主要可概括为：（１）地气异常元素组合具有相似性，主要元素为Ｗ、Ｓｂ、Ｌａ、Ｓｍ、Ｃｏ、Ｋ和Ｎａ等微量元素和造岩元素。对隐伏含矿破碎带，除出现上述元素地气异常外，还叠加有与矿化密切相关的成矿元素及其伴生元素的地气异常。（２）在地气异常形态上，主要呈现异常“群”的分布特点，异常位置均出现在隐伏断裂的正上方；异常的宽度基本上反映了隐伏断裂破碎带的宽度。对地气样品进行多种扫描探针显微技术证实，地气样品上沉积的物质是以纳米级微粒及其集合体的形式存在的。
Geo-gas measurement technology is the capture and determination of trace metals and non-metallic elements in subsurface ascending gas to reveal deeper formation information. In this paper, the characteristics of ground anomalies above different kinds of buried faults are discussed, which can be summarized as follows: (1) The anomaly of ground anomaly elements are similar and the main elements are trace elements such as W, Sb, La, Sm, Co, K and Na And rock-forming elements. For the concealed ore-bearing fractured zone, in addition to the anomalous gas anomalies mentioned above, anomalous geogas of ore-forming elements and associated elements closely related to mineralization are also superimposed. (2) In the abnormal gas-state morphology, the distribution of anomalous “clusters” is mainly presented, and the anomalous sites appear just above the buried faults; the anomaly width basically reflects the width of the buried fracture zone. Multiple scanning probe of ground gas samples Microscopy of the probes confirmed that the material deposited on the ground gas sample is in the form of nano-sized particles and their aggregates.
