内蒙古自治区地域辽阔,地跨华北地台、天山、内蒙古中部、兴安地槽等大地构造单元(内蒙古自治区区域地质志1982)。自太古代以来,伴随多次构造运动,岩浆活动强烈,且期次繁多,形成的岩浆岩分布广泛。直到本世纪初,热液型铀矿勘查工作重新引起重视,我队相继做了区内基础地质编图和部分重点地区钻探工作,取得了阶段性的成果。本人根据工作经验结合前人认识,对内蒙古热液型铀成矿条件进行浅析,希望对今后内蒙古热液型铀矿找矿工作提供一定的 The Inner Mongolia Autonomous Region has a vast territory spanning the North China Platform, Tianshan Mountains, central Inner Mongolia, Xing’an Trough and other geotectonic units (Inner Mongolia Autonomous Region Geological 1982). Since the Archean, with many tectonic movements, the magmatic activity is intense, and the period is numerous, forming a wide range of magmatic rocks. Until the beginning of this century, the investigation of hydrothermal uranium deposits has re-emphasized the work. Our team has successively done basic geological mapping and drilling in some key areas in the area, and achieved initial success. Based on my working experience and my understanding, I analyzed the hydrothermal uranium metallogenic conditions in Inner Mongolia, hoping to provide a certain amount of prospecting for hydrothermal uranium deposits in Inner Mongolia
