Uranium Ore Controls of the Happy Jack Deposit, White Canyon, San Juan County, Utah

Description: Abstract: The Happy Jack uranium deposit of White Carron, San Juan County, Utah, was studied in connection with an Atomic Energy Commission exploration program. The major uranium ore control is a paleostream channel containing sediments of the Shinarump conglomerate. Intrachannel controls include organic matter, lithologic variations, and channel "lows". Microscopic studies reveal that uraninite, the primary ore mineral, occurs as cement and as a replacement of organic material. Both the uraninite and copper sulfides replace secondary quartz overgrowths. Crystals of chalcopyrite, chalcocite, and pyrite occur one within the other. Resolution of bornite and chalcopyrite is present. Uraninite is dated as later than the secondary overgrowths and of about the same age as the copper sulfides.
