Discussing the results of core drilling for uranium-bearing carbonaceous shale and lignite in the Goose Creek District, in Cassia County, Idaho

From Abstract: "It is proposed that diffusion be considered as a possible process of isotope fractionation taking place throughout geologic time. Both diffusion in solids and in liquids are considered as possible mechanisms, the latter being more important. Arguments are presented which show that if significant fractionation takes place within a crystal by outward diffusion under solid state conditions, enrichment will be evident only in elements of minor concentration."
