Relationship of phreatic reformation to the formation of Shazaoquan uranium deposit

Study shew that the formation of Shazaoquan uranium deposit is closely related to phreatic reformation. In vertical direction, the reformation by phreatic leaching directly control the depth of rock alteration, geochemical zonation and orebody depth, and in the plane, the flow of phreatic water deter mine the reformation space which control the positioning and shape of uranium orebody. It was believed that there is better and larger orebody in the east of the deposit. (authors)
