摘　　要：讨论了蒙古地质构造与矿化,同时介绍了一些已知铀矿床与研究程度很高的含铀区的地质特征。在蒙古版图上可以划分出4个铀成矿省。铀矿床、铀矿点勘探表明,该区有8个含矿建造。根据多尔诺特东部、古尔万布拉克、马丹格尔、尼莫尔、哈拉特南部和纳尔斯矿床勘探资料,对估计资源量(RAR+EAR-Ⅰ)进行了评估。火山杂岩中铀矿床与地表氧化有关的水成铀矿的估计总资源量为147万t。已探明的铀资源量占总铀资源量(RAR+EAR-Ⅰ)的4.0%(5.9万t)。在东戈壁省,一个新的近地表大型矿区已被发现,是一个含有铀-稀土的复合型矿床。Uranium ore-formation and epochs of uranium mineralization in Mongolia have been discussed in the paper, highly studied uranium- meanwhile the geological characteristics of some known uranium deposits and bearing areas are introduced. Four metallogenetic provinces can be divided in Mongolia. Exploration of uranium deposits and occurrences shows that eight ore-bearing formations occur in the area. According to the exploration in East Dornot, Gurvanbulak, Mardaingol, Nemer, South Kharat, Nars, estimated resources（RAR＋EAR-I）are evaluated. The total estimated resources of surfacial oxidation related hydrogenetic uranium deposit in volcanic complexes are 1.47×10^6 t, and proven resources account for 4.0% （5.9×10^4 t）of total uranium resources. A new large subsurfacial mining area has been discovered in East Gobi Province, and it belongs to a uranium-rare metal complex type.
