Origin and Role of Kaolinization in Roll-Front Uranium Deposits and Its Response to Ore-Forming Fluids in the Yili Basin, China
Figure 9
(a) Organic fluid containing CO, CH4, and H2S occurred from coal beds and carbonaceous mudstones during shallow-burial diagenetic stage and entered into sandstones while flowing from the basin bottom to top. (b) Meteoric water containing U and O2 infiltrated interlayered sandstones, forming oxidation zones, white micritic kaolinization zones, and uranium orebodies.
