Metallogenetic conditions and exploration criteria of the Dongsheng sandstone type uranium deposit in Inner Mongolia, China

The Dongsheng uranium deposit differs from other sandstone type deposits. It has unique signatures and is generally controlled by a transitional zone between greenish and grayish sandstones; both of them indicate reduced geochemical environments. It is genetically different from ordinary sandstone uranium deposits and of more complex origin. Understanding metallogenetic conditions and concluded exploration criteria of this type uranium deposit are of both theoretical and practical significances in exploration for similar kind of uranium deposits.
