Fluviatile Deposits of the Athabasca Formation of Northern Saskatchewan: Abstract

Paul Ramaekers1

Analysis of over 3000 paleocurrent measurements in association with sedimentological data and measured sections indicate the presence of several deposystems in the eastern and central Athabasca Basin. The eastern systems derive from the Wollaston Fold Belt and form broad fans with coarse gravels at their apices that grade into sands within a short distance. Silts and clays are notably scarce. Thickness of the sedimentary cycles, variance in current direction, and the type and frequency of sedimentary structures vary down-current. The sequence is interpreted as a group of broad, coalescing alluvial fans grading into a plain traversed by shallow braided streams and subject to strong eolian influence.
