摘　　要：大兴安岭中南段地质背景复杂,区内铀矿化主要以火山岩型为主,大多数分布于中生代火山盆地内。笔者通过对区内地质资料的系统收集、整理和综合分析,结合编图和野外调查,初步查明该地区的铀矿化特征、控矿因素和成矿规律,总结出3种铀矿化类型,并预测了6片铀成矿远景区,为今后在大兴安岭中南段地区开展铀矿找矿工作,提供了找矿方向及思路。The uranium mineralization in the middle-southern as volcanic-type mineralization, most of which distribute Great Xing＇an Range is mainly classified in the Mesozoic silicic volcanic basins. Through systematic research on the collected materials, geological survey map compilation and comprehensive study, the mineralization characteristics, ore-controlling factors and metallogenie pattern were identify in this area. Two kinds of uranium mineralization were determined and 6 uranium metallogenetie prospects were predicted in this area, which provide reference for further uranium exploration.
