内蒙古查干哈达地区铀矿化特征及找矿方向

摘要

查干哈达地区处在中蒙边境的中端巴音宝力格铀成矿带上,隶属于内蒙古地槽褶皱系艾勒格庙-锡林浩特中间地块西端.笔者通过对该区地层和岩体的含铀性、热液蚀变、构造等成矿条件及铀矿化特征、控矿因素等进行分析,探讨了区内今后的铀矿找矿方向,期望为找矿新突破提供有益的思路.%Chaganhada area is located in the middle Bayan bulag uranium metallogenic belt between China and Mongolia,which belongs to the west part of Aleg Xilinhot intermediate massif in Mongolia geosyncline fold system.By studying the metallogenic condition such as uranium content of rocks,hydrothermal alteration and structure and the mineralization characteristics,the ore controlling factors was analyzed,and the prospecting orientation was discussed for the future exploration in this area.
