| 中文摘要: |
| 文章以萨热克砂砾岩型铜多金属矿勘查为例,运用综合物探方法进行找矿研究。大功率时间域激电扫面可快速获得全区的激电异常,圈定异常查证区。音频大地电磁测深能获得地下深部的电性特征,对地层岩性进行划分,达到深部地质填图的目的。单极—偶极测深工作可对激电异常做更精细的解释,指导钻探验证。综合这3种物探方法,构建工作区地下地质结构构造、圈定和评价铜矿体富集空间,取得了较好的找矿效果。 |
| 英文摘要: |
| Taking a case study on the exploration of Sareke glutenite type copper polymetallic deposit,the comprehensive geophysical prospecting method was applied. The IP anomalies through the whole deposit area can be obtained quickly by using the high-power time domain spectrum induced polarization survey, and the verified anomaloys areas can be outlined in a rapid way. Audio frequency magnetotelluric sounding method can obtain electrical characteristics of the deep underground, which can used for classification of lithological units and for the purpose of deep geological mapping. Pole-dipole IP sounding survey can make a further explanation for IP anomalies, which will guide the drilling engineering verification. By using above-mentioned three kinds of geophysical exploration methods, the underground geological structures were constructed, and the spatial position of copper enrichment was delineated and evaluated, and sounding prospecting effect was achieved in the Sereke copper deposit area. |
