| 摘 要： | 广西凤山县金牙金矿经过近30年的开采,现面临严重的资源危机,急需开展深部找矿工作。金牙金矿是滇黔桂地区较为典型的微细粒浸染型金矿,主要以断裂构造控制为主,为了查清矿区断层在深部的产状与延伸情况,笔者在该金矿区参与开展了CSAMT工作,布设了7条CSAMT剖面,通过带地形的二维反演计算,并结合矿区地质特征等对7条剖面进行解译,指出了矿区F1、F2控矿断裂在深部较准确的位置。经钻孔验证,取得了良好的找矿效果,表明CSAMT法在本区寻找金矿是有效的,可在滇黔桂地区深部找矿工作中发挥重要作用。

| Abstract: | After nearly thirty years of mining, now the Jinya gold deposit faces serious crisis of resources, so it urgently needs mineral prospecting toward the deep subsurface. This gold mine is typically of micro-disseminated gold in the Yunnan-Guizhou-Guangxi area, which is primarily controlled by faults. In order to clarify the occurrence and extension of faults in the deep subsurface of the mining area, a CSAMT project was carried out on seven profiles. Through two-dimensional inversion of the profiles with topography, in combination with the geological characteristics of the mining area, the accurate locations at depth of ore-controlling faults F1 and F2 are determined. Drilling verification shows that the ore-search results of this method are satisfactory, which indicatesthat the CSAMT method is effective. This method will play an important role in prospecting toward the deep subsurface in the Yunnan-Guizhou-Guangxi areas. |
