喀喇昆仑萨岔口-火烧云一带铅锌矿成矿规律及成矿模式研究

Study on metallogenic regularity and metallogenic model of lead-zinc deposits in sachakou huoshaoyun area,Karakoram

研究区位于喀喇昆仑山脉东段新疆和田县境内,随着地质找矿工作不断拓展,已在该区乔尔天山大断裂一带发现了一系列铅锌矿找矿线索。本文通过对研究区成矿地质条件、矿产分布特征、典型矿床特征等方面的分析研究,总结了萨岔口-火烧云一带的区域成矿规律,重点分析了铅锌矿床的控矿地质因素,建立了沉积-交代型铅锌矿和MVT型铅锌矿的区域成矿模型,为本区后续铅锌找矿及矿产勘查工作提供了方向及参考。

The study area is located in Hotan County,Xinjiang,in the eastern part of the Karakoram mountains.With the continuous expansion of geological prospecting,a series of lead-zinc prospecting clues have been found in the Qiaoer Tianshan fault area.Through the analysis and research of metallogenic geological conditions,mineral distribution characteristics and typical deposit characteristics in the study area,this paper summarizes the regional metallogenic law in sachakou huoshaoyun area,focuses on the ore controlling geological factors of lead-zinc deposits,and establishes the regional metallogenic models of sedimentary metasomatic lead-zinc deposits and MVT lead-zinc deposits,which provides direction and reference for the follow-up lead-zinc prospecting and mineral exploration in this area.
