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

Paleo-climate evolution in China and its control on the metallization of sandstone type uranium deposit of Meso-Cenozoic 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。

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.
