内蒙古阿拉善地区铁铜金多金属矿成矿规律及找矿前景

阿拉善地区横跨华北板块北部陆缘增生带、华北地块、塔里木板块东部陆缘增生带与哈萨克斯坦板块东南陆缘增生带，是一个多构造单元的结合部位，具有潜在的找矿前景.根据这一特殊的成矿地质环境，对该地区已有矿床（点）的分布、矿床类型及成矿地质背景进行了详细研究，总结了雅干-哈日奥日布格、塔木苏格拉格-本巴图、阿贵庙-叠布斯格3个成矿区带的成矿地质特征及其成矿规律，并进行了找矿前景分析.

METALLOGENIC REGULARITY AND PROSPECTING POTENTIAL OF IRON-COPPER-GOLD-POLYMETALLIC DEPOSITS IN ALXA AREA,INNER MONGOLIA

The Alxa area is situated in the conjunction of multiple tectonic units with prospecting potential. It stretches across the northern epicontinental accretionary zone of North China Plate, the North China Block, the eastern epicontinental accretionary zone of Tarim Plate and the southeastern epicontinental accretionary zone of Kazakhstan Plate. Based on the specific metallogenic geological environment, the paper conducts a detailed study on the distribution of deposits and ore occurrences, types and mineralization geological background, then summarizes the geological characteristics and metallogenic regularity of three metallogenic belts, namely Yagan-Har Orbog, Tamusugelage-Bumbat and Aguin Sum-Diebusige, and finally analyzes the prospecting potential.
