S>On the Colorado Plateau uranium is associated with coalified wood, crude oil, carbonaceous shale, and carbonaceous matter of unknown origin. Investigations have shown that crude oil plays no role in the emplacement of uranium, although its ability to pick up small quantities of uranium while migrating through uraniferous zones may make oils an aid to general prospecting. Carbonaceous matter with no cellular structure that occurs as impregniations in sandstones or as pellets has been chemically related to coal and is thought to represent a coal extract. The reduction to U(IV) of uranium associated with coalified wood may take place after absorption of the uranyl ion. Study of a terrestrial shale shows that the uranium is associated with carbonaceous material similar to lignite in chemical composition. From these studies it is concluded that the fundamental association of uranium with carbonaceous material on the Colorado Plateau is with coalified wood and allied chemical substances. (auth)
