新疆若羌县喀拉乔喀地区锡铜多金属矿化特征与找矿方向探析

Discuss on the metallogenic features and prospecting direction of Kalaqiaoka tin-copper deposit in Ruoqiang County,Xinjiang

新疆若羌县喀拉乔喀地区新发现了一系列锡铜矿化线索。本文通过对喀拉乔喀地区的成矿地质背景、物化探异常与矿化蚀变特征进行综合研究,分析了该地区的成矿规律、找矿潜力及找矿方向,认为矿(化)体赋存于侵入接触带与近南北向断裂的叠加部位,与岩浆成因物化探异常吻合较好,具备寻找岩浆热液-(类)矽卡岩型锡、铜多金属矿的良好条件,开展进一步工作有望取得较好的找矿效果。

A series of clues to tin copper mineralization have been discovered in Kalaqiaoka area,Ruoqiang County,Xinjiang.Based on a comprehensive study of the metallogenic geological background,geophysical and geochemical anomalies,and mineralization alteration features,this paper analyzed the metallogenic regularity,prospecting potential and prospecting direction in Karaqiaoka area.It was considered that the ore(chemical)body occurs in the superimposed position of intrusive contact zone and nearly north-south fault,which was in good agreement with the geophysical and geochemical anomalies of magmatic genesis.There are good conditions for prospecting for magmatic hydrothermal-skarn(skarn-like)tin-copper polymetallic deposits in Karaqiaoka area,and it is expected to achieve excellent prospecting results in future work.
