| 摘 要： | 砂金沟区Ⅱ号角砾岩带规模较大,构造复杂。角砾岩是赋矿母岩,金矿(化)体与黄铁矿化关系密切,离矿(化)体越近,黄铁矿化越强,极化率就越高,矿化角砾岩与围岩有明显电性差异。在Ⅱ号矿化角砾岩带开展的激电中梯和激电测深工作取得了较好的效果,指导了钻探工程,解决了地质问题,成果得到验证。

| Abstract: | The No.Ⅱ breccia zone of Shajingou area is larger in scale,with complex structure.Breccia is ore-hosting rocks,gold mineralized bodies and pyritization are closely related,the mineralized body closer,the pyritization is stronger,and the polarization rate is higher,mineralized breccia rock and surrounding rock have obvious electric difference.In the No.Ⅱmineralized breccia zone,IP intermediate gradient and IP sounding job obtained better result,guided the drilling project,solved the geologic problems,and verified the results. |
