| 摘 要： | 运用1∶ 1 万高精度磁测方法，对1∶ 5 万矿产调查工作中发现的地球化学异常及克力代金矿点深部隐伏控矿构造及矿化蚀变进行评价。结果表明，高精度磁测不仅可以圈定隐伏的控矿构造，确定有利成矿区带，而且可以进一步圈定隐伏的强、弱磁性矿体。对克力代金矿点矿化蚀变带的1∶ 1 万高精度磁法测量数据解译表明，该矿化蚀变区内，由4 条深部隐伏断裂围限，形成了强磁性背景场下的局部低负异常区带，说明深部隐伏断裂构造及矿化蚀变等造成的降磁作用较强，暗示深部具有较大的成矿潜力。

| Abstract: | The geochemical anomaly found in 1 ： 50000 mineral survey and the deep hidden ore-controlling structure and mineralization alteration in Kelidai gold deposit are evaluated with 1：10000 high-precision magnetic measurement. The results indicate that high-precision magnetic measurement can not only delineate the ore-control- ling structure to find favorable ore forming legion, but also locate the concealed strong or weak magnetic ore bodies further. The 1：10000 high-precision magnetic data interpretation in Kelidai gold deposit alteration region showed that the region was limited by four deep concealed faults and formed local low and negative anomaly under strong magnetic background, indicating that the magnetic reduce caused by deep concealed faults and alteration was strong with favorable metallogenic potential in deep. |
