| 摘 要： | 为了研究地气微粒特征在探测隐伏矿体中的指示意义,采用地气静态测量法采集滇东北永胜得铜矿区隐伏矿体上方地气纳米微粒,通过高分辨的透射电子显微镜和能谱,对所采集的样品微粒进行形貌分析和元素种类、含量测定后,发现微粒中元素组合特征随着矿体或矿化蚀变带的存在与否出现相应的变化。用地气测量法原理可以较好地解释这一现象,即由脱气作用形成的地气流在从地球深部垂直向上迁移过程中,穿过地质体,吸附具有特征性的微粒并携带至地表,引起相应的元素种类差异和含量异常。这意味着结合这些微粒元素组合特征和地质背景,可以较直接地判断隐伏矿体的有关特点,为找矿工作提供帮助。

| Abstract: | In order to study the significance of the characteristic and elements of the particles carried by geogas in prespectinging for concealed deposits,the particles from Yongshengde copper ores in the Northeastern Yunnan were collected by using static geogas technique.After using ATM and EDS to test the patterns,we discovered that the character of the particle shapes and element associations changed as the diversification of the deposits or mineralizes.We can explain this phenomena well through the theory of the Geogas,and the explanation is : The Geogas took the particles from the geologic bodies on its way from the deep to the surface,causing anomalies of the particles and their elements.This presumes that we can integrate these particles and their elements to analyze the location,style,genesis,character and so on of an insidious deposit through a relatively straight way. |
