我国中新生代古气候演化及其对盆地砂岩型铀矿的控制作用

摘要

This paper analyzed the climate evolution of China in Meso-cenozoic and indicated that climate in Early Jurassic, Middle Jurassic , Early Cretaceous and Late Cretaceous was favorite for the forming of uranium deposit and produced corresponding uranium bearing strata. The paper have set up the system of paleo-climate evolution in China and discussed the control role of modern climate on uranium metallization in the basins.%文章在分析我国中新生代古气候演化的基础上,指出早侏罗世、中侏罗世及早白垩世、晚白垩世是我国盆地砂岩型铀矿形成的有利古气候期,并在盆地中形成了相应的赋矿层位；建立了我国中新生代产铀盆地3种古气候演化系列；探讨了近代气候对盆地铀成矿的控制作用.
