URANIUM-BEARING AURIFEROUS REEFS AT JACOBINA, BRAZIL

· Economic Geology and the Bulletin of the Society of Economic Geologists (U.S.)
Near Jacobina, Brazil, are uranium-hearing gold deposits in reef-type conglomerates of Proterozoic age. Uraninite and gold occur in association with pyrite in the matrix of closely packed quartz pebble cerglomerates. A comparison of the geological and geochemical features is made with the Witwatersrand gold ores and the Blind River uranium deposits, leading to the conclusion that, in the three widely separated areas, the deposits are the product of a similar metallogenetic cycle of erosion, sedimentation, and mineral deposition restricted to a late Precambrian epoch.
