Ore Genesis of Typical Uranium Polymetallic Deposits in Black Rock Series in Southwestern China
Black rock series, which are widely distributed in Southwestern China, Distribute mainly in the upper Sinian-Lower Cambrian, Silurian system, Permian and Triassic.In the black rock series in Southwestern China, there are many typical deposits, which are with many similar characteristics, has close relationship with the regional deep fault, lithology, magmatism-fluid activity.Numerous Uranium polymetallic deposits, uranium polymetallic occurrences and mineralized spots are widely distributed in the black rock series.In the black rock series in Southwestern China, there are many typical deposits, such as Zoige deposit (510) of Sichuan, Baimadong deposit (504) in Guizhou and Daxin deposit (373) of Guangxi.The Zoige deposit (510) of Sichuan is discussed in this paper.In Southwestern China, higher concentration of uranium in black rock series by sedimentation and Diagenetic stage is the prelude of the black rock series-type uranium deposits.The metallogenic way and scale of reformation and superposition are essential condition for the formation of typical uranium deposits in black rock series.A necessary trilogy to the formation of typical uranium polymetallic deposits in black rock series in Southwestem China are Prelude, Reformation and Superposition.
