Age ID Locality Notes Giersdorf_00000991 Uranium vein-type deposits located in the Otish Mountains basin (Quebec) are associated with strongly albitized doleritic dykes and sills. Two periods of mineralization were recognized. The first, contemporaneous with the albitization, consists of brannerite and uraninite. The second, separated from the previous by tectonic movements, is characterized by carbonate gangue (dolomite), and a complex association of selenides, tellurides and sulfides including: skippenite, watkinsonite, poubaite, soucekite, clausthalite, aikinite, wittichenite, molybdenite, pyrite, chalcopyrite, galena, digenite, covellite, electrum, native bismuth, and several unidentified bismuth selenides-tellurides.
