摘　　要：通过分析中国北方中新生代盆地构造演化特征,研究构造演化对盆地沉积地层、盆内构造的变化影响。以伊犁盆地蒙其古尔铀矿床、松辽盆地大庆长垣铀矿床为例,说明盆地构造演化是形成富含铀沉积建造的先决条件,同时也是后期叠加富集的必要条件,揭示以后应加强盆地构造演化研究,通过构造改造演化特征以寻找目标层位和有利成矿位置。By analyzing the tectonic evolution characteristics of the Meso-Cenozoic basins in northern China,the impact of tectonic evolution on the sedimentary strata and internal structures of the basins was studied.Taking the Mengqigul uranium deposit in the Ili Basin and the Daqing Changyuan uranium deposit in the Songliao Basin as examples,it was illustrated that basin tectonic evolution was a prerequisite for the formation of uranium rich sedimentary structures,and also a necessary condition for later superimposed enrichment.It revealed that in the future,research on basin tectonic evolution should be strengthened,and target horizons and favorable mineralization locations should be identified through structural transformation and evolution characteristics.
