哈西哇地区属东昆仑伯喀里克-香日德印支期金、铅、锌、铁、铜、镍(稀有、稀土)成矿带,随着勘查程度的提高,成矿较为显著.根据区域地质学研究,早中泥盆世构造岩浆阶段为碰撞晚期(后碰撞)构造环境,整个东昆仑西段表现为持续性的伸展体制,岩浆活动(特别是幔源岩浆活动)极为强烈,东昆仑地区铜镍矿床就是在这种岩石圈构造伸展环境下,大量幔源岩浆深部熔离和上侵贯入形成的产物,即夏日哈木等区成矿作用的具体体现.本文通过对哈西哇地区地球化学特征及找矿前景分析研究,得出一定找矿前景.
Geochemical characteristics and prospecting prospects of copper and nickel elements in the Hasiwa region
The Hasiwa region belongs to the East Kunlun Bokalik Xiangride Indosinian gold,lead,zinc,iron,copper,and nickel(rare and rare earth)mineralization belt.With the improvement of exploration degree,mineralization is more significant.According to regional geological research,the Early to Middle Devonian tectonic magmatic stage was in the late collision(post collision)tectonic environment,and the entire western section of the East Kunlun Mountains exhibited a sustained extensional system,with extremely strong magmatic activity(especially mantle derived magmatic activity).The copper nickel deposits in the East Kunlun region were formed by the deep melting and upward intrusion of a large amount of mantle derived magma in this lithospheric extensional environment.The specific manifestation of mineralization in areas such as Hamu in summer.This article analyzes and studies the geochemical characteristics and prospecting prospects of the Hasiwa region,and obtains certain prospecting prospects.
