Deposits that contain uraninite and sulfide minerals at Heaths Peak, Carbon County, Wyo., display a zoned distribution of metals from the edge of granite into adjacent metamorphic rocks. The metallic minerals---uraninite, molybdenite, pyrite, chalcopyrite, galena, pyrrhotite, and marcasite---are concentrated on the undersides of metamorphosed roof pendants. At the Little Man mine, deposition was related to a small cupola projecting into the central part of an elongate pendant. The host rocks and the deposits are of Precambrian age.
