...Kathleen M. Vannelli; A. Guy Plint; Robin A. Buckley; Jessica R. Krawetz; Celeste M. Cunningham Abstract An allostratigraphic approach was used to investigate the stratigraphy of the Late Albian Joli Fou and Pelican formations across 77 000 km 2 of east-central Alberta. Although the Pelican...

Regional paleogeographic synthesis of the Pelican and Paddy depositional systems, based on Rylaarsdam (2006), Buckley (2011) and Vannelli (2016). The north-eastern part of the Pelican delta system is conjectural because the rocks have been removed by post-Cretaceous erosion. Similarly, the degree to which the Joli Fou Sea flooded the Canadian Shield is unknown. A branch of the Pelican distributary system crossed the Smoky River Ridge, possibly following a paleovalley (outlined in grey) mapped by Leckie et al. (1990). This branch of the river system debouched into the southern extremity of the Polar Ocean on the west side of the Smoky River Ridge. Rivers from the Cordillera drained into a region of extensive shallow, brackish-water bays and lakes, building small lobate deltas that were protected from the open sea by a linear strandplain system to the north. The remnant of the Joli Fou-Viking Sea was isolated from the Polar Ocean by the Pelican delta in the north, and in the south from the Gulf of Mexico by a subaerial ridge in southern Kansas and Oklahoma (Dolson and Muller, 1994). In consequence, the sea is likely to have become increasingly brackish over time. This isolation may explain the absence of a fully marine macrofauna from the Viking Formation and equivalent strata, such as the Muddy Sandstone in the United States (e.g. Stelck, 1958; Eicher, 1960; Mellon, 1967; MacEachern et al. 1999c).

Major structural aspects of the junction region between the Glennie, La Ronge, and Rottenstone domains (WB, Wathaman batholith; TMC, Tonalite–migmatite complex), emphasizing the Pelican thrust mylonite zone and the various tectonic windows produced by antiformal fold closures in it. (a) Geological map showing the mylonite zone of the Pelican thrust (black). The hanging-wall block of the Pelican thrust is composed in the east mainly of Paleoproterozoic volcanics and granitoids stacked in a series of overlapping thrust allochthons. In the west, these Paleoproterozoic allochthons are stacked on top of the subsurface extension of the Archean Hearne Craton, which crops out to the west (see cross-section C–C′ in (c)). These allochthons have been folded by syn- to post-thrusting cross folds to form a series of domes in the Pelican thrust, resulting in the formation of two tectonic windows exposing the Sask Craton: IW, Iskwatikan window; HW, Hunter Bay window. Early thrust faults, probable splays off the Pelican thrust: GCT, Guncoat thrust; HSZ, Hartley shear zone; BRSZ, Birch Rapids shear zone. Needle Falls shear zone (NFSZ) is a ductile strike-slip structure bounding the northwest side of the Wathaman batholith. Tabbernor fault (TF) is a late sinistral strike-slip structure. The Phanerozoic sedimentary cover consists of flat-lying clastic and carbonate rocks < 100 m thick. C–C′ shows the location of a north–south cross section (see (c)). (b) Block diagram of the region shown on the map (a), emphasizing the Pelican thrust; based on down-plunge projection techniques, as well as data from seismic lines 9, S1A, and S2C. Symbols are the same as used in (a). (c) Cross section C–C′ constructed using data projected from the geological map and the seismic lines. The position of the Moho is generalized. Symbols are the same as used in (a) and (b), except for additional symbols shown.

A) Position of Alberta (AB) and Saskatchewan (SK) in North America. B) The three main oil sands regions, Peace River, Athabasca, and Cold Lake are demarcated by the black polygons. The blue shaded area in the Athabasca oil sands region marks the approximate limit of the McMurray Fm and time-equivalent strata, herein referred as the McMurray Formation depocenter (MDC). The margins of the MDC in the south, west, and north are derived from the AEUB (2003), while the eastern extent is theoretical and is based on surface projections and basin reconstruction presented in Jean (2018). The arrows in Part B demarcate the main paleovalley axes as defined by depositional lows on the Sub-Cretaceous Unconformity. The study area is outlined by the red rectangle. C) Isopach map of the McMurray Fm in the study area with maximum thicknesses observed along the axes of the Pelican, Sparrow, and Grouse paleovalleys and minimum thicknesses over the carbonate highlands. Pelican, Sparrow, and Grouse are secondary paleovalleys that drained into the Assiniboia Valley (Christopher 1997; Horner et al. 2018).
