Uranium mineralization occurs in the Jackpile sandstone, the uppermost unit in the Brushy Basin Member of the Morrison Formation (Jurassic), north of Laguna, New Mexico. Mineralization ranges from discontinuous, spotty disseminations to lenses up to 30 ft (10 m) thick and 100 ft (30 m) long. The lenses are elongate subparallel to the northeast trend of the Jackpile sandstone. Since 1952, observations during mining have indicated that varied forms of mineralization occur within lenses, such as rodlike features, irregular and diffused masses, and discontinuous seams or wisps crosscutting channel boundaries. The positive correlation between uranium content and organic carbon for samples greater than 0.04 percent U/sub 3/O/sub 8/ suggests that organic carbonaceous material is a major large-scale controlling factor for the deposition of uranium. No other significant geochemical control on mineralization can be postulated from the limited data presented.
