| [摘要]通过变比例尺的高精度磁测在新疆库兰矿区快速准确地圈定了重点磁异常区。对重点
异常区设计了高精度磁法和电阻率层析成像剖面精测,结合岩石的磁性和电性参数对重点精测剖面比
对,发现了矿区内重要的隐伏断裂构造和侵入岩体,为寻找有利成矿带提供了地球物理依据。对比邻近
野马泉金矿区成矿类型发现,控矿岩体为闪长玢岩体,因此推测本矿区内的高磁异常带为隐伏的含矿闪
长玢岩体成矿带。通过后期探槽的揭露发现成矿带矿化明显,深部找矿潜力巨大。 |

| Abstract:The method of surface high-precision magnetic measurement in different scale is applied in Kulan gold deposit. 5 high accuracy survey
lines including high precision magnetic measurement and resistivity tomography method are designed in this area and an important structural belt and intru鄄
sive rock are found by analyzing the rock samples爷magnetic and electrical parameters, which is a key to metallogenic prediction. It indicates that this
structural belt and intrusive rock is a metallogenic belt by comparing with Yemaquan gold deposit爷s metallogenic type which is structural ore-control and
its ore-control rock is dioritic porphyrite. It predicts that the high magnetic anomaly in Kulan gold deposit is caused by this dioritic porphyrite rock. This
prediction is proved in late trenching exploration and mineralization in this metallogenic belt is obvious, which indicates there is a good potential in this ar鄄
