摘要
地气测量在反映金矿的深部盲矿方面 ,取得了很好的试验效果 .为扩大应用范围 ,在已知气田进行试验 ,其结果能够反映 40 0 0m深的环状断裂构造 ,异常位置在构造的垂直上方 .另外 ,土壤中有 2组微量元素异常 ,间接指示了含气范围 .此外 ,进行了多种扫描探针显微术观测 ,发现采样器上沉积的物质是以纳米微粒及其集合体形式存在的 。
Geogas prospecting is an effective method for the location of the concealed gold deposit. In order to popularize this method, many experiments have been made in the known gas fields. The geogas prospecting has thus revealed the ring fracture structure 4?000?m deep and the location of the geogas anomaly above the ring fracture structure perpendicular to each other. In addition, two groups of trace element anomalies in the soil, indirectly indicate the gas_bearing range. Finally, several kinds of high_resolution scanning_probe microscopes have been employed to observe the geogas anomaly. The results show that the substance deposited on the collectors occurs in the forms of nano_scale particles and their aggregate, providing us with the evidence for the research into the mechanism of the geogas anomaly.
