摘　　要：亚欧东西向活化构造铀成矿带,其铀资源量约为全球的50%,是全球最重要的大陆洲际铀成矿带。该带地质构造和成矿复杂,活化构造作用延续时间最长,从早元古宙至今断续发生活化作用,以中新生代活化最为强烈。文章从大地构造及其演化控矿的角度,以铀成矿域为单元,对划分该铀成矿带的大地构造、深部构造、地球物理、地球化学和铀成矿分布等依据及铀成矿域分布作初步论述。Over half of the global uranium resources occurred along the eastwest activated Eurasian tectonic belt which is the most important in the world.The geological structure and uranium mineralization are complicated in the belt.From early Proterozoic ,the tectonic activity occurred intermittently ,Especially in the Mesozoic and Cenozoic period , the activity were the most strongest.In this paper , the basis of the geotectology , deepcrustal stracture ,geophysicgeochimistry and distribution of uranium mineralization were discussed for the division of the reactivated tectonic uranium metallogenic belt and the distribution of uranium mineralization provinces from the views of geotectonics and evolution ore controlling.
