Proposing metallogenic viewpoint of fault-uplift and its geological significance

Regional geological setting, uranium mineralization characteristics, as well as relationship between uranium mineralization and gas and oil for Dongsheng uranium deposit in northern Ordos basin are discussed detailedly in this paper by utilizing the post-remote sensing application technology. On the basis of that, the metallogenic viewpoint of fault-uplift for sandstone type uranium deposit was proposed, which emphasizes the important significance of fault and deep material in the process of sandstone type uranium ore-formin. The study enriches the metallogenic theory of sandstone type uranium deposit to some extent and provides a new direction for further uranium prospecting in Ordos basin. (authors)
