Sedimentary framework of uranium deposits in the Southern Cobalt Embayment, Ontario, Canada
Description
Uranium concentrations in the basal Huronian (lower Aphebian) strata of the Cobalt Embayment are associated with, but not always confined to, pyritic resistate pebble conglomerates. Placer concentrations of ilmanite and magnetite formed in mid fan and valley bottom fluvial systems resembling Scott and Donjeck type braided stream models; uranium was introduced into the system, along with some gold, during diagenetic alteration of ilmanite-magnetite placers to pyrite by acid-oxidizing groundwaters: in places uranium was remobilized during upper greenschist facies metamorphism and migrated to adjacent mudstone units.
