AbstractThe Manitou Falls Formation, deposited during the early evolution of the eastern Athabasca Basin, is composed of flat-lying, unmetamorphosed sandstone and conglomerate that change stratigraphically upward from polymictic pebble conglomerate to medium-grained quartz arenite. This succession has been subdivided into lithofacies that are diachronous by nature. Variations in lithofacies and
paleoenvironment are useful for lithostratigraphic correlation, but do not allow resolution of chronostratigraphic horizons.

Drill cores along two transects were studied, thickness of fluvial fining-upward successions were recorded, and these were plotted stratigraphically. Thickness of fining-upward intervals is used as a proxy for accommodation. These show systematic changes from times of low accommodation marked by coarse-grained intervals followed by gradual shifts to greater accommodation and finer grained intervals. A hydrostratigraphic model for the eastern Athabasca Basin is presented based on integration of sedimentology, sequence stratigraphy, and diagenesis. The two basal sequences contain aquifers that onlap basement rock units eastward and focused burial brines.
