摘　　要：以新疆哈密月牙湾铜镍矿区为研究对象,通过开展地面高精度磁测,重力、激电面积测量等工作手段,快速圈定找矿有利地段,再通过重磁电综合精测剖面,土壤地化剖面及岩体含矿性,最后以激电测深与CSAMT相结合的方法组合勾勒出异常深部地质特征,探寻深部有利找矿空间。通过对资料的综合分析,圈定了由重力剩余高值异常、磁力正异常、高极化率异常、低电阻率异常组成的具硫化物矿化超基性岩“三高一低”异常部位为找矿靶位,初步建立了该区的地质-地球物理-地球化学综合找矿模型,为工程验证提供了依据,取得了较为理想的找矿效果。Yueyawan copper nickel mining area in Hami,Xinjiang is taken as the research object,through ground high-precision magnetic survey,gravity and IP sounding survey and other work means,the favorable prospecting areas are quickly delineated.Then through the gravity,magnetic and electric comprehensive precise survey profile,soil geochemical profile and rock ore-bearing property,finally,the combination of IP sounding and CSAMT methods are used to outline the geological characteristics of the anomaly depth in this area in order to explore for the deep favorable prospecting space.Based on the comprehensive analysis of the data,the"three high and one low"anomaly areas of ultrabasic rocks with sulfide mineralization,which are composed of gravity residual high value anomaly,magnetic positive anomaly,high polarizability anomaly and low resistivity anomaly,are delineated as the prospecting target areas.The comprehensive geological,geophysical,geochemical prospecting model is preliminarily established.It provides the basis for engineering verification and there is a relatively ideal prospecting result in the mining area.
