摘　　要：金格勒铜矿是近年来在准噶尔东北缘新发现的一处斑岩型铜矿床,具有中大型矿床找矿潜力。在地质研究基础上,通过开展多尺度重磁电面积测量,在研究区内圈定了多处综合物探异常。结合研究区物性特征对比分析,认为区内激电极化率异常是矿化蚀变带的直接找矿标志,弱高磁异常与后期侵入的闪长岩脉有关。据地质勘查成果,在地表蚀变带、激电极化率异常套合较好的位置选择成矿有利地段进行深部验证,圈出了多条铜工业矿体,总结了研究区斑岩型铜矿综合找矿模型,为区内铜矿找矿突破提供了有益指导。The Jingele copper deposit is a porphyry Cu-deposit newly discovered in the northeastern margin of Junggar in recent years,which has the prospecting potential of medium and large deposits.On the basis of geological research,the author determined several comprehensive geophysical anomalies in the inner ring of the mining area by carrying out multi-scale gravity,magnetic and electric area measurement.Combined with the comparative analysis of the physical properties of the mining area,it is considered that the induced polarization anomaly in the area is the direct prospecting indicator of the mineralized alteration zone in the area,and the weak high magnetic anomaly is related to the diorite vein intruded in the later stage.According to the geological exploration results,the favorable metallogenic sections were selected at the locations where the surface alteration zone and induced polarization anomaly fit well for deep verification,and a number of Copper Industrial orebodies were delineated.The comprehensive prospecting model of porphyry copper deposits in the study area was summarized,which provided useful guidance for the breakthrough of copper prospecting in the area.
