| [摘要]为了扩大资源储量,降低找矿风险,文章运用大地电磁法、地电化学法与吸附相态汞方法
组合在高原寒冷地区开展物化信息进行金矿预测研究。通过已知区可行性研究验证方法组合的找矿成
效,总结适合高原寒冷景观条件下的物化探找矿模式,即金矿通常位于Au 地电化学异常正投影下方、电
阻率高低突变带偏低阻体一侧,配套土壤吸附相态汞异常寻找破碎带型金矿较有效。依据上述找矿模
式,在忠曲矿区开展金矿预测工作,在矿区西部发现找矿有利地段3 处,东部发现找矿可疑地段1 处。 |

| Abstract:To expand the resources reserves and reduces the risk of prospecting ore deposit, Geoelectric chemical extraction method, controlled鄄SoIl鄄
rce audio magnetite Hurlc method and the method of measuring the adsorbed mercury in the surface soil as a whole method, which get the Synthesis infor鄄
mation is effective to locate the ore deposit. So we carry on that combination to forecast the gold ore in the cold area of plateau. Through the feasible re鄄
search on existing ore by technique combination, we found it effective to detect the deposit. The gist of locating ore mine adapted is, the gold ore is usual鄄
ly under the Au electrochemistry unusual normal, tending to the side of low electronic resistivity in the Intermediate belt which is between low and high e鄄
lectronic resistivity. Combine with absorbed鄄Hg鄄phase measurement as help is effective for the exploration for concealed gold deposit . This method found
three advantageous sector in the west of the Zhongqu minefield and one suspicious sector in the east, by the gist above. |
