Sequence Stratigraphy of the Upper Cretaceous Sego Sandstone Member Reveals Spatio-Temporal Changes In Depositional Processes, Northwest Colorado, U.S.A

Abstract: The Upper Cretaceous Sego Sandstone Member of the Mesaverde Group has been extensively studied in the Book Cliffs area of Utah and Colorado, and has been the focus of stratigraphic reconstruction aimed at developing an understanding of the evolution of the Western Cretaceous Interior Seaway. The Sego Sandstone Member was deposited in a marginal marine, tide-influenced environment of the Cretaceous Seaway. This study documents the sequence stratigraphy of the Sego Sandstone Member in northwestern Colorado, just… Show more

“…This interpretation is consistent with independent structural geological interpretations suggesting that the Uinta uplift was rising beginning in the Late Cretaceous (Bradley, ; Gregson and Erslev, ). Southeastward palaeocurrent indicators from the Campanian Sego Sandstone exposed south of the Uinta Mountains (Willis & Gabel, , ; Painter et al ., ) are also consistent with late Campanian Uinta uplift, and southward palaeocurrent indicators from the Currant Creek Formation indicate that deformation of the Uinta uplift was well underway by Maastrichtian time (Isby & Picard, ).…”

“…Changes in regional process regimes and deep-water sedimentation styles may result in significant changes in stratal stacking patterns that can be tied to specific types of shelf-edge trajectories (e.g., Yoshida et al, 2007;Catuneanu et al, 2009Catuneanu et al, , 2011Dixon et al, 2012a, b;Painter et al, 2013). Recognition of shelf-edge growth styles and their relation to process regime changes are useful in predicting volumes of coeval sandstone on the slope and basin floor (Dixon et al, 2012a, b).…”

“…It is not feasible to measure strictly the subaerial portion of ancient barrier island deposits because the water line moves through time and deposits are potentially subject to removal during ravinement. Additionally, the foreshore is rarely specifically designated in literature examples (Allen and Johnson, 2011;Kieft et al, 2011;Painter et al, 2013). Inversely, subaqueous width measurements for the modern are not feasible at a global scale because they are inhibited by the scarcity of available data and the difficulty in defining, constraining, and documenting the subsurface back-barrier and shoreface boundary without ground penetrating radar or seismic data (Jol et al, 1996;Daly et al, 2002;Wernette et al, 2018).…”
