“…The dominant paleocurrent direction in White River Uplift was southwestward from 80.7 Ma to 80.2 Ma (Li & Aschoff, 2022b). The presence of 1,800–1,600 Ma zircons in the Santonian Mancos Shale of the Piceance Creek Basin offers evidence for the onset of nearby uplift (Lynds & Xie, 2019).…”

Variability in subsidence rates within Upper Cretaceous strata of the Western Interior Basin offers crucial insights into the response of surface sedimentation styles to Sevier‐to‐Laramide tectonics and related deep mantle processes. The formation mechanisms of the Late Cretaceous Western Interior Basin in North America have long been a subject of debate. A re‐evaluation of the basin's subsidence history reveals rapid subsidence pulses lasting ca. 2 Myr within longer‐term (average 5.7 Myr) progradational or aggradational clastic wedges. The timing of these wedges, especially the widespread marine flooding resulting from subsidence, is constrained through the calibration of ammonite zonation with absolute dates. Sevier wedges exhibit a different architecture compared to the Laramide wedges. The former recorded initial rapid and widespread marine transgressions followed by long‐term coastal progradation, whereas the latter developed by initial erosional and progradational growth followed by aggradation and long‐term coastal transgression. The Sevier clastic wedges, initially accumulated within a N‐S elongated, long‐wavelength tectonic subsidence zone close to the thrust belt, gradually migrated cratonward. Starting in the early Campanian (ca. 82 Ma), the Laramide Orogeny developed along a NW‐SE trend and then migrated northeastward, roughly consistent with coeval long‐wavelength frontal basin subsidence. The spatio‐temporal variations in long‐wavelength tectonic subsidence indicate a shift in the dynamic subsidence's migration direction from eastward to northeastward, driven by changes in Farallon subduction direction and mode. Our work shows how repeated subsidence behavior in the Sevier‐to‐Laramide transition records evolving architectural responses and the trajectory of coeval dynamic topography.

“…During the late Campanian to Paleogene (starting at ca. 75 Ma), deformation within the CFB became dominantly thick‐skinned (i.e., Laramide orogeny), and the CFB became locally segmented by intraforeland Laramide‐style basement‐cored uplifts (Bartschi et al, 2018; Dickinson et al, 1988; Lawton, 2008; Lynds & Xie, 2019; Yonkee & Weil, 2015) (Figure 1). These Laramide‐style uplifts can cause flexure in adjacent areas and likely would locally interfere with the flexural subsidence caused by loading of the Sevier fold‐thrust belt and mantle‐induced dynamic subsidence (Aschoff & Steel, 2011; Heller & Liu, 2016; Li & Aschoff, 2022a; Saylor et al, 2020).…”

“…For a similar reason, the local west–east trended area of minor tectonic subsidence south of the Uinta uplift (Figure 6a,b) could be attributed to the early stage of the Uinta uplift, consistent with the timing of the Uinta uplift (ca. 75 Ma) indicated by detrital zircon provenance data (Bartschi et al, 2018; Lynds & Xie, 2019).…”

Mantle-induced dynamic topography (i.e., subsidence and uplift) has been increasingly recognized as an important process in foreland basin development. However, characterizing and distinguishing the effects (i.e., location, extent and magnitude) of dynamic topography in ancient foreland basins remains challenging because the spatio-temporal footprint of dynamic topography and flexural topography (i.e., generated by topographic loading) can overlap. This study employs 3D flexural backstripping of Upper Cretaceous strata in the central part of the North American Cordilleran foreland basin (CFB) to better quantify the effects of dynamic topography. The extensive stratigraphic database and good age control of the CFB permit the regional application of 3D flexural backstripping in this basin for the first time. Dynamic topography started to influence the development of the CFB during the late Turonian to middle Campanian (90.2-80.2 Ma) and became the dominant subsidence mechanism during the middle to late Campanian (80.2-74.6 Ma). The area influenced by >100 m dynamic subsid-ence is approximately 400 by 500 km, within which significant (>200 m) dynamic subsidence occurs in an irregular-shaped (i.e., lunate) subregion. The maximum magnitude of dynamic subsidence is 300 ± 100 m based on the 80.2-74.6 Ma tectonic subsidence maps. With the maximum magnitude of dynamic uplift being constrained to be 200-300 m, the gross amount of dynamic topography in the Late Cretaceous CFB is 500-600 m. Although the location of dynamic subsidence revealed by tectonic subsidence maps is generally consistent with isopach map trends, tectonic subsidence maps developed through 3D flexural backstripping provide more accurate constraints of the areal extent, magnitude and rate of dynamic topography (as well as flexural topography) in the CFB through the Late Cretaceous. This improved understanding of dynamic topography in the CFB is critical for refining current geodynamic models of foreland basins and understanding the surface expression of mantle processes.

“…The Laramide-age Rock Springs uplift began to form around 79 Ma (Lynds and Xie, 2019). The center of the uplift is cored by the older Baxter and Blair Formations (Schultz, 1920) and the Rock Springs Formation is present around this anticlinal structure in beds that dip away from the center of the uplift (Yourston, 1955) (figure 1).…”

“…While it is clear that a foreland basin was present, the basin was likely subdivided or broken by Laramide deformation, which complicates the standard foreland basin model (DeCelles, 2004;Rudolph and others, 2015). Laramide deformation probably began after deposition of the Rock Springs Formation (as early as 79 Ma; Gosar and Hopkins, 1969;Lynds and Xie, 2019), but a pre-Laramide deformational history may have had a local positive effect on subsidence (Hagen and others, 1985).…”

The Upper Cretaceous Rock Springs Formation of the Mesaverde Group in northwestern Colorado, southwestern Wyoming, and northeastern Utah is composed of fluvial, deltaic, and marine sediments that record the regression of the Western Interior Seaway during the Early to Middle Campanian. Contemporaneous deposits are present along the eastern and southeastern margins of the Greater Green River Basin in Wyoming, but correlation across the basin is challenging. Analysis of a small (1-km-long), understudied outcrop in northwestern Colorado assists in bridging that gap. The outcrop consists of distal and proximal deltaic deposits, overlain by distributary-channel complexes within delta-plain deposits. Correlation panels based on subsurface wireline logs and outcrop gamma-ray profiles show that the deposits are younger than lithostratigraphically equivalent strata of the Rock Springs Formation in Utah and Wyoming. Regional nomenclature is introduced for the area, and it is shown that these deposits differ from better-documented, older Rock Springs Formation deposits in Utah and Wyoming by having a higher net sandstone percentage due to the presence of substantial distributary-channel complexes. This study benefits subsurface exploration efforts in the Greater Green River Basin by providing outcrop analogs of reservoir distribution and quality.
