青海都兰县伊和让贵铜矿区地球物理特征及成矿潜力分析

Geophysical Characteristics and Metallogenic Potential Analysis of the Yiheranggui Copper Mine Area in Dulan County,Qinghai Province

青海省都兰县伊和让贵铜矿区内圈出9处辉长岩体,岩体主要沿F3、F4及其他近东西向构造线呈岩株状展布,岩体空间分布形式为断续重现。岩体暗色组分多,颜色较深,化学成分Cu、Ni、Co、Pt、Pd等元素含量较高,岩体偏基性。此次通过开展1∶5000磁电工作,圈出多处物探异常,通过分析物探异常反映深部岩体及对应矿体的延伸拓展情况,推测深部可能存在超基性岩体。通过开展地球物理工作,在该区发现多处物探异常,异常显示岩体向深部延伸稳定,说明该区有一定的成矿潜力。

There are 9 gabbro bodies are encircled in the Yiheranggui copper mining area in Dulan County,Qinghai province.The gabbro bodies are distributed along F3,F4 and other near east-west structural lines,and the spatial distribution pattern of the gabbro bodies is intermittent.The rock mass has high dark composition and darker color with high contents of Cu,Ni,Co,Pt,Pd and other elements.Through 1∶5000 magnetoelectric work,many geophysical anomalies were delineated,and by analyzing the geophysical anomaly reflecting the extension of deep rock body and corresponding ore body,it was inferred that there might be ultrabasic rock body in deep.Through geophysics work,many geophysical anomalies have been found in the area,which indicate that the rock mass extends steadily to the deep,indicating that the area has a certain metallogenic potential.
