| Abstract: | The sandstone type mineralization of Zhiluo Formation in the southeast of Ordos Basin obviously relates to the reformation of oil-gas fluid. It is analyzed that the space distributing character of oil-gas fluid, the epigenetic alteration reformation of oil-gas fluid in sand body from the point of macroscopical and microcosmic, discussed the stage of oil-gas fluid activity and the relationship between oil-gas fluid with mineralization of sandston-hosted uranium deposits, it＇s of important meaning to the research uranium mineralization pattern and prognostication. |
