AbstractThe ca. 1.74 - 1.64 Ga lower Athabasca Group comprises four regional formations distributed among five fluvial depositional systems that prograded into the Athabasca Basin from different directions. Understanding these deposystems should aid exploration for the world's richest uranium deposits located at the basal unconformity with gneissic basement. Fair Point Formation conglomerate and coarse-grained lithic sandstone were transported westerly via the oldest, Fidler deposystem, preserved only in western Athabasca Basin. The Robert deposystem introduced Smart Formation sandstone from the southwest, onlapping the Fidler deposystem. A contemporary eastern phase of the Ahenakew deposystem introduced the Read Formation conglomerate, pebbly mudstone, and sandstone from the south and east. Finally, the broadly coeval Ahenakew, Karras, and Moosonees deposystems deposited the Manitou Falls Formation
from the east, southeast, and northeast, respectively. The five Manitou Falls Formation members become thinner, finer, and indistinct toward the west where they overlap the Robert and Fidler deposystems.
