| 摘 要： | 云南富宁水合口金矿位于滇东南文山―富宁成矿带,属于著名的滇黔桂"金三角"地区。利用landsat 8OLI遥感影像对研究区进行1∶100 000矿化蚀变信息提取,结合区域地质和化探异常等多元信息进行找矿预测,表明矿化蚀变、断裂构造交汇处和地球化学异常空间叠加部位为有利找矿地区,圈定了5个找矿远景区,为研究区开展下一步找矿提供了科学依据。

Extraction of information about mineralization and alteration of Shuihekou deposit in Funing of Yunnan and prognosis for prospecting |
| |
| Abstract: | Shuihekou gold deposit is located at Wenshan-Funing metallogenic belt in southeast Yunnan which is part of the famous Yunnan-Guizhou-Guangxi “golden triangle”area.By applying Landsat8 OLI remote sensing image,this paper carried out extraction of information about mineralization and alteration at 1:100 000 scale in the study area,and it conducted prognosis for prospecting based on the data of regional geology and geochemical anomalies.The results indicated that where the intersections between mineralization-alteration area and fracture structures were superimposed with geochemical anomalies were favorable prospecting areas. Totally five prospecting potential areas were blocked out and the study provided scientific basis for future prospecting works in the study area. |
