摘　　要：黄土坡矿床是东天山卡拉塔格地块发育的一个典型的早古生代铜锌矿床,随着资源开采程度的提升,矿山铜锌保有储量不足,深部及边部找矿增储迫在眉睫。本文通过分析研究区地质特征及成矿规律,结合物探异常特征对该区找矿方向进行了总结。黄土坡矿床具明显的构造控矿特征,受热液活动影响,矿体产于早古生代大柳沟组硅化及黄铁绢英岩化火山碎屑岩中。矿体与低电阻率和高极化率电性异常特征及高背景值下的低磁异常套合好,是该区有效的找矿方法组合。选择大功率电法物探设备加大探测深度及范围,在NW向导矿构造附近对已有激电异常及电阻率异常开展大比例尺扫面及测深工作,并开展高精度磁测工作,重点查找受构造控制的侧伏及深部隐伏盲矿体是进一步勘查找矿方向。Huangtupo Mineral deposit is a typical early Paleozoic copper-zinc deposit developed in Kalatage district,East Tianshan Mountains.However,with the improvement of resource exploitation degree,the reserve of copper and zinc in the mine is insufficient,and it is urgent to find ore in deep and side.This paper summarizes the prospecting direction of this area by analyzing its geological characteristics and metallogenic regularity and combining with geophysical anomaly characteristics.The Huangtupo Mineral deposit has obvious structural ore-controlling characteristics.Influenced by hydrothermal activities,the ore body is produced in the early Paleozoic volcaniclastic rocks of Daliugou Formation,which are silicified and pyritic sericitization.The ore body is well integrated with the characteristics of low resistivity and high polarizability electrical and low magnetic anomalies,which is an effective combination of prospecting methods in this area.High-power electrical geophysical exploration equipment is selected to increase the detection depth and range,and large-scale scanning and sounding work is carried out to the existing IP anomalies and resistivity anomalies near the NW guiding ore structure.High precision magnetic survey is also an effective way.The further prospecting direction is to focus on the lateral and deep concealed blind ore bodies controlled by structure.
