Summary(Plain Language Summary, not published)
The formation tops for Cretaceous strata in the Mackenzie Plain and Peel Plain regions are the result of multi-year analysis of well log, seismic, and outcrop data. The stratigraphic geometries of Cretaceous strata in the study are quite complex due to the interleaving of unconformities. In places the basal unconformity is overlain by Albian strata, in other places it merges with the sub-Slater River Formation unconformity that is overlain by Cenomanian strata, and it even merges with an intra-Little Bear Formation unconformity that is overlain by Campanian strata. Each of the various unconformities has eroded deeper into underlying strata over the Keele Arch, which exerts first-order control of the stratigraphic thickness and consequently the thermal maturity of hydrocarbon source rocks in the area.
