| 摘 要： | 辽东地区高家峪组地层中,由于地层岩性中的含墨性,形成的高极化率异常值(低电阻率异常值)往往高于(低于)矿致异常值,严重影响了物探方法找矿效果,有的地区甚至无法开展物探找矿工作.本文以钓鱼台金银矿找矿为例,通过对矿区的地层岩性结构、成矿地质条件及控矿、容矿地质构造的分析,进行岩矿石电性测定,采用激电中梯和音频大地电磁组合方法进行综合探测,建立起含墨地层岩性的异常响应模型,并对矿致异常进行正确的识别和划分,经钻探验证取得了较好的找矿效果.

| Abstract: | Due to the graphite contained in the Gaojiayu Formation in Eastern Liaoning area,the anomaly value of high polarizability is often higher than that of ore-induced anomalies,while that of low resistance is commonly lower.That seriously affects the prospecting results of geophysical methods.In this paper,the exploration in Diaoyutai Au-Ag deposit is analyzed as an example.On the basis of the stratigraphic and lithologic structure,metallogenic geological conditions and ore-controlling and ore-host structures,the electrical properties of rocks and ores are measured.With IP intermediate gradient and AMT combined method,the abnormal response model is established for the graphite-bearing strata,by which the ore-induced anomalies are correctly identified and classified.The verification drilling shows a good result. |
