Geologic setting

Geologic description

Analyses of three samples from three nearby localities are reported by White (1952, p. 8-9): 1) Sample no. 48AWe90 is heavy mineral concentrate from stream gravels and contains an altered unknown uraniferous mineral containing Fe, Ti, Al, and Si, and 0.016 percent eU at 8200:1 concentration ratio; 2) Sample no. 48AWe99 is heavy mineral concentrate from disintegrated rhyolitic dike and contains unknown orange and translucent Ca- and P-bearing uraniferous mineral with dull luster, and 0.060 percent eU at 2000:1 concentration ratio; also contains hematite with uraniferous impurity; 3) Sample no. 48AWe100 is from crushed fragments of fresh rock at same locality as sample no. 48AWe99, and contains minute radioactive particles on weathered surfaces and altered fractures in euhedral pyrite, and 0.030 percent eU at 450:1 concentration ratio.
