“…Jurassic deposits record marine to nonmarine basin filling, which is typical of foreland basin clastic wedges (Table 1) (Cant and Stockmal, 1989;Fuentes et al, 2011;Miles et al, 2012;Kukulski et al, 2013;Raines et al, 2013). Overall, the thickness of these units is controlled by variations in accommodation and differential erosion of pre-Cretaceous units during incision of the sub-Cretaceous unconformity ( Fig.…”

“…Samples that plot closer to the Grenville and Gondwanan synthetic populations, including those of Group 1 from Great Falls, are interpreted to record recycling of sedimentary strata from the southwestern United States (Dickinson and Gehrels, 2009b;Leier and Gehrels, 2011;Gehrels and Pecha, 2014), or deposition from continental-scale river systems such as interpreted for Cold Lake (Blum and Pecha, 2014). Samples that plot closer to the Trans-Hudson synthetic population are interpreted to derive from uplifted passive margin strata in the northern Cordillera (Leier and Gehrels, 2011;Laskowski et al, 2013;Raines et al, 2013;Gehrels and Pecha, 2014;Quinn et al, 2016). Samples that cluster near the Jurassic synthetic population include samples that are similar to Group 2 from Great Falls and record provenance dominated by Cordilleran magmatic rocks (Fig.…”

“…New data are integrated with previously presented data sets from across the basin in order to consider the history of burial and exhumation of the frontal toe of the orogenic wedge ( Fig. 1) ( Fuentes et al, 2011;Leier and Gehrels, 2011;Raines et al, 2013;Benyon et al, 2014;Blum and Pecha, 2014;Quinn et al, 2016). This study emphasizes the potential impact of wedge-top dynamics on sediment dispersal across foreland basins and the structural evolution of the orogen.…”

The Late Jurassic to Early Cretaceous fill of the Western Interior foreland basin is characterized using geochronological data in order to assess the stratigraphic expression of wedge-top geomorphology, as controlled by sediment cover and denudation. In northern Montana, USA, and Alberta, Canada, wedge-top deposits are poorly preserved; however, their former presence may be inferred from the detrital record in the foreland basin. We present new U/Pb detrital zircon data from nine samples collected near Great Falls, Montana, augmented with field data. The stratigraphy at Great Falls is characterized by Late Jurassic marine and nonmarine deposits, which are truncated by a basinwide sub-Cretaceous unconformity. Aptian and lower Albian strata overlying the unconformity are dominated by nonmarine deposits, which transition up-section into a predominantly marine succession related to a major transgression of the Boreal Seaway in the Albian.Detrital zircon grains from Great Falls strata yield age spectra that can be subdivided into three groups using multidimensional scaling. Group 1 is characterized by diverse zircon populations, which are interpreted to record recycling of pre-Cordilleran sedimentary strata transported via foreland basin-axial river systems with headwaters in the southwestern United States. Group 2 is characterized by the dominance of Mesozoic detrital zircon grains, which are interpreted to record sediment dispersal by fluvial systems with headwaters in the Cordillera. Group 3 is intermediate between groups 1 and 2, based on its proportion of Mesozoic zircon grains. This group records a diversification of the provenance from one dominated by Cordilleran igneous rocks to include recycled sedimentary strata.New data are integrated with three other data sets from Montana and Alberta such that stratal thicknesses (a proxy for accommodation development) and provenance evolution can be compared across the basin. The detrital record in each area, which transitions from diverse provenance to predominantly Cordilleran through the entire stratigraphic section, can be linked to the burial of the pre-foreland strata in the wedge-top depozone. This record elucidates a period of evolution of the western margin of North America to a more Andean-type system with primary input to the basin from an active magmatic arc.

“…The presence of possible detrital pyroxene and muscovite in the Fourth member of the Shilu Group (Xu et al, 2009) excludes the long-distance transport or episodes of sediment recycling as well as the varied provenances for our studied successions, but indicates the tectonic setting of retro-arc foreland basin (Fig. 10) with the depositional provenance directly from the orogen (e.g., Raines et al, 2013). This is consistent with the metamorphogenic zircons of the main age population of 1200-1000 Ma (Fig.…”

“…The earliest preserved foreland strata were deposited from the Late Jurassic (Kimmeridgian) to Early Cretaceous (Valanginian), when sediment was supplied to the Canadian portion of the basin by both local rivers and a continent-scale, north-flowing drainage system with headwaters in the southwestern and possibly also the southeastern United States (Williams and Stelck, 1975;Wright et al, 1994;Raines et al, 2013). In the Berriasian to Barremian, diminished tectonic activity in the Rocky Mountain Cordillera, resulted in widespread erosion and isostatic uplift of Upper Jurassic to Lower Cretaceous sediments in the foredeep (Leckie and Cheel, 1997;Leier and Gehrels, 2011).…”

Lower to upper Coniacian rocks in the foredeep of the Western Canada Foreland Basin are dominated by mudstone and subordinate sandstone and were deposited on a very low-gradient, storm-dominated marine ramp. The rocks are organized into several scales of upward-coarsening, upward-shoaling succession, bounded by marine flooding surfaces. Abundant, publicly available wireline log data permit flooding surfaces to be traced for hundreds of kilometers in subsurface. Flooding surfaces can be considered to approximate time surfaces that allow the subsidence history of the basin to be reconstructed. Particularly widely traceable flooding surfaces were chosen, on pragmatic grounds, as the boundaries of 24 informal allomembers, most of which can be mapped along the foredeep for >750 km. Allomembers can also be traced westward into the fold-and-thrust belt to outcrop in the Rocky Mountain Foothills. Some flooding surfaces are mantled with intra-or extrabasinal pebbles that imply a phase of shallowing and, potentially, subaerial emergence of part of the ramp.The rocks yield a rich and well-preserved molluscan fauna dominated by inoceramid bivalves and scaphitid ammonites. Several major inoceramid speciation events are recognized. The lowest occurrence of Cremnoceramus crassus crassus, various species of Volviceramus, Sphenoceramus subcardissoides, and S . pachti all appear immediately above major flooding surfaces, suggesting that speciation,
