西昆仑塔尔—库斯拉甫一带Pb、Zn化探异常成因及找矿前景分析

A Brief Analysis of the Prospect and Causes of Pb,Zn Geochemical Exploration Anomalies in the Area of Tal-Kuslap of Western Kunlun

研究区经1 5万水系沉积物测量化探取样,根据样品测试结果共圈定4个Pb、Zn化探异常区,结合室内综合数据整理及野外异常成因分析,得出该地区Pb、Zn异常分3种类型:密西西比河谷型(MVT)、热液充填型和花岗斑岩型。其中,密西西比河谷型(MVT)异常区具有分布面积大、强度高、相关元素叠加性好的特点,是该地区铅锌矿的一级找矿前景区。

150,000 stream sediments were surveyed in research area,and four delineated Pb,Zn areas of geochemical exploration anomalies were found in accordance to the test results of samples.Combining the indoor sorting of comprehensive data and the outdoor analysis of anomaly verifies,three types of Pb,Zn anomalies were found in this area： Mississippi Valley type（MVT）,hydrothermal filling type and granite-porphyry type.Among which the Mississippi Valley type（MVT） is a large area of anomaly distribution with high strength and a good overlap with correlative elements.It is the first-level prospect of lead-zinc ore in the region.
