水系沉积物测量在新疆霍什布拉克地区找矿应用

摘要

1 ∶ 50,000 stream sediment survey in Hoos Braque area revealed distribution patterns, enrichment and dispersion regularity of the major ore-forming elements in this area. On the basis of analysis of regional metallogenic conditions, the Hs46b2 composite anom-aly was preferentially picked out for geological integrated prospecting, and a new medium-sized karst breccia type lead-zinc deposit was found in northern Qiongqia Te area. The newly-discovered deposit is helpful to the prospecting for the same type of deposits in carbonate formations along foreland thrust-fold belts in southwest Tianshan Mountains.%通过对新疆西南天山霍什布拉克地区1∶5万水系沉积物测量，总结了区域主要成矿元素的分布型式、元素富集与分散规律。在综合分析研究区域成矿地质条件的基础上，择优选择了Hs46乙2综合异常开展地质综合找矿，新发现琼恰特北岩溶角砾岩型中型铅锌矿床。该矿床的发现对于西南天山造山带前陆盆地边缘碳酸盐岩建造寻找同类型铅锌矿床具有一定的指导意义。
