| 中文摘要: |
| 为缓解湖南锡矿山锑矿资源危机,寻找接续资源。在锡矿山北部的稻草湾矿区开展可控源音频大地电磁测深(CSAMT),揭露该区受断裂和地层联合控制的隐伏锑矿体,以期在危机矿山深边部取得找矿突破。本次工作共布设7条探测剖面,通过对探测数据进行预处理和静态校正,以及二维反演计算,基本查明了稻草湾矿区控矿断裂的分布特征,推断了隐伏矿体的标高位置。经钻孔验证,揭露的断裂构造和矿体的位置与CSAMT解译结果基本吻合,表明CSAMT法在该区找锑具有较好的效果,可为锡矿山深边部找矿提供地质依据。 |
| 英文摘要: |
| In order to alleviate the resource crisis of Xikuangshan antimony deposit in Hunan Province and to search for continued resources. Controlled source audio-frequency magnetotelluric sounding (CSAMT) was carried out in the Daocaowan mining area in the north of Xikuangshan to reveal the concealed antimony orebody controlled by faults and strata in order to make a breakthrough in prospecting in the deep and border areas of crisis mines. Through preprocessing and static correction of the detection data, as well as 2D inversion calculation, the distribution characteristics ore-controlling faults in Daocaowan mining area are basically found out, and the occurrence elevation position of concealed ore bodies is inferred. The borehole verification shows that the revealed fault structure and the location of ore body are basically consistent with the interpretation results of CSAMT survey, which shows that CSAMT method has a good effect on antimony prospecting in this area, and can provide geological basis for ore prospecting in the deep and border areas of Xikuangshan. |
