Abstract:
Jurassic coal measures and sandstone uranium deposit directly coexisted in space in Dongsheng area, Ordos basin. In order to discuss the relationship of coal measures and uranium deposit, extensive field exploration and systemic indoor analysis were conducted. Based on the research of coal features, diagenetic succession and ge- ochemical features of coal measures,it is discovered that uranium content continuously increase during the diagen- esis stages from turf to lignite and is in direct proportion to content of vitrinite in group macerals of coal, diage- netic minerals of sandstone correlate to coalification, and contents and features of trace element and REE of coal concide with that of uranium-bearing sandstone. It is concluded that effects of coal on uranium include sorption, complexation and revivification in syngenesis and early diagenesis and coal measures have positive effect on redis- tribution and preservation of uranium deposit in the epidiagenetic stage.
