AbstractMetallogenic studies of the Athabasca Basin metallogenic province in Alberta indicate favourability of the basement and overlying Athabasca Group rocks for uranium- polymetallic mineral deposits. The basement rocks include Archean and Aphebian granitoid and Aphebian metasedimentary rocks with layers of pyritic graphitic metapelites. Regolith typically is present at the top of the basement rocks. Elevated values of uranium are associated with granitic rocks, particularly with alkali feldspar-rich granitoids, the Fishing Creek granitoids, and grey foliated granitoids; and with felsic mylonite, chloritized graphitic-pyritic metapelite and altered pegmatoids. Nickel mineralization is associated locally with chloritized biotite gneiss. The Athabasca Group rocks contain polymetallic mineralization, particularly at the sub-Athabasca unconformity, where it is intersected by faults. A typical polymetallic assemblage contains uranium, nickel, arsenic, cobalt, molybdenum and zinc. Elevated contents of chromium have been found in rocks of the study area.
