摘要:

夹皮沟金矿床位于华北地台北缘东部,分布于夹皮沟—海沟—松江河金成矿带上。该矿床已有200余年的开采历史,但保有储量迅速减少,因此探矿增储迫在眉睫。在野外地质工作的基础上,结合高精度磁法测量与岩屑地球化学测量等勘查手段,认为Au、W、Ag、S、Ni、Te等元素具有较高变异系数,显示出较好的找矿潜力;岩体展布方向与区域构造一致,北东向构造与磁异常解译环形构造交汇部位为找矿有利位置;圈定了3处找矿靶区,并对其进行了找矿潜力评价,为进一步找矿提供了依据。

Abstract:

Jiapigou Gold Deposit is located in the east of the northern rim of North China Platform and distributed on the Jiapigou-Haigou-Songjianghe gold metallogenic belt.The deposit has a mining history of over 200 years.However,its reserves are depleting so fast that exploration and reserve improvement are urgent.Outdoor geological work,high-precision magnetic survey and rock debris geochemical survey are combined and take that Au,W,Ag,S,Ni,Te have relatively high variation coefficients,indicating good prospecting potentials;the rock body distribution direction is consistent with regional tectonics,and the junction of NE structures and magnetic anomaly interpretation ringed structure is a favorable place for prospecting;3 prospecting target areas are delineated and evaluated on their prospecting potentials,laying foundation for further prospecting.
