 Dongsheng uranium deposit in Ordos Basin is an important large sandstone-type uranium deposit. By electronic microscopy, the thesis has made a detailed research on the uranium mineral’s category and output characteristics. It has been identified that the main uranium minerals are coffinite and ursilite which are both epigenetic mineral.  It can also be found that micro-vein uranium assemblages penetrate through the quartz clast. It has been researched that the uranium element is dissolved (transferred) and deposited (enriched) repetitively under the epigene.
