内蒙古呼伦贝尔市北阿布打沟地区铅锌矿地质特征及找矿标志

Geological characteristics and prospecting indicators of lead-zinc deposits in North Abu Dagou area,Hulunbuir,Inner Mongolia

北阿布打沟地区处于内蒙-大兴安岭成矿省(Ⅱ2),额尔古纳河燕山期(钼)金、银、铅、锌成矿带(Ⅲ5),莫尔道嘎金、铅、锌成矿带(Ⅴ51),区内成矿地质条件优越,物化探异常明显,具有较好的资源前景。本文以《内蒙古自治区呼伦贝尔市平安等五幅1:5万区域矿产地质调查》项目为依托,较详细地阐述了该区区域地质背景和矿区地质特征,并对其找矿标志进行了简要分析,为该区寻找热液型铅锌矿提供了借鉴。

The North Abu Dagou area is located in the Inner Mongolia-Great Xing’an Mountains Metallogenic Province(Ⅱ2).The Erguna River Yanshanian(molybdenum)gold,silver,lead,and zinc metallogenic belt(Ⅲ5),Moerdaoga gold,lead,zinc Ore Belt(Ⅴ51).The mineralization geological conditions in the mining area are superior,the geophysical and geochemical prospecting anomalies are obvious,and it has good resource prospect.Based on the project of"1:50,000 Regional Mineral Geological Survey of Five Sites in Ping'an,Inner Mongolia Autonomous Region",this article elaborates on the regional geological background and geological features of the mining area in more detail,and briefly analyzes its prospecting signs.It provides a reference for finding hydrothermal lead-zinc deposits in this area.
