Abstract
镜儿泉西地区出露十多个规模不等的镁铁质超镁铁质岩体，规模较大者约为0.02平米千米，且辉长岩中发育孔雀石化，为较好的找矿线索。本文通过在覆盖区较为适用的高精度重磁测量方法，对镜儿泉西铜矿化点开展评价。本次工作共圈出高重力异常8个和高磁异常7个，为基性-超基性岩引起，是寻找与基性–超基性岩有关的铜镍矿有利部位。 More than ten mafic and ultramafic complexes with larger scale about 0.02 square kilometers are presented in the western Jingerquan, eastern Tianshan, NW China. Base on the high precision gravity and magnetic measurement method in coverage area, we carry out the evaluation to the copper mineralization point in the western of Jingerquan in Hami. In this work, we delineated 8 high gravity anomalies and 7 high magnetic anomalies, which are caused by the basic ultrabasic rocks, and all of these anomalies are the favorable position to find the Cu-Ni mineralization which is related to basic ultrabasic rocks.
