The roles of organic matter in the formation of uranium

Because reduced uranium species have a much smaller solubility than oxidized uranium species and because of the strong association of organic matter a powerful reductant with many uranium ores reduction has long been considered to be the precipitation mechanism for many types of uranium deposits Organic matter may also be involved in the alterations in and around tabular uranium deposits
