Abstract: Shishugou deposits occur in the upper carboniferous Benxi group carbonate unconformity surfaces, and are strictly controlled by sedimentary discontinuous surfaces.The bauxite is large and stable; Orebody is layered or lay-like structure; Ore structure types are massive or layered structure; The main mineral compositions are diasporite and kaolinite; The harmful elements are less and associated with gallium elements, etc.Deposits by humid tropical climate change and formation of clay is closely related to mineralization, the different size depressions and dissolved buckets formed on the erosion surfaces are the positioning spaces of the bauxite; The gulf lagoon deposition is favorable conditions for the bauxite bed formation.The deposits belong to main bauxite after short distance handling-machinery sedimentary, and have good bauxite metallogenic prospects.
