| 摘 要： | 金平地块位于扬子克拉通西南缘,该地区岩浆熔离型铜镍硫化物型矿床产于与二叠系峨眉山玄武岩有成因联系的基性-超基性侵入岩体中,赋矿围岩及矿石的物性特征与其它非含矿岩石具有明显的差异,对航测所获得的特定频率(900 Hz)电磁异常及磁异常进行分析,结合地面地质检查和物化探测量工作,对有望成矿潜力区进行快速远景评价. |
| 关 键 词： | 铜镍矿床 机载电磁测量系统 快速评价 金平地块 |

| Abstract: | The Jinping block is located on the western margin of Yangtze craton. In this area, the magmatic liquation and pulsatory injection type copper and nickel ore deposits lie in ultramafic and mafic intrusions, which are genetically related to the Permian basalts of southwest China. These deposits share good geophysical features suitable for EM survey. The Helicopter-towed Electromagnetic Survey, as a very useful advanced exploration method for targeting mineralization, is employed in the prospecting for copper and nickel sulfide deposits and, combined with ground geological, geochemical and geophysical survey, can be expected to locate the target area quickly and accurately for follow-up work. |
| Keywords: | copper and nickel mineralization HEM Survey quick targeting and evaluating of potential mineralization Jinping block |
