“…Johnson (1984) named the freshwater phase of the Lake Uinta in the Piceance Basin the Cow Ridge Member, and the member has been extensively mapped throughout the Piceance Basin. The name Cow Ridge Member was also originally applied to the Uteland Butte interval where it crops out in the easternmost part of the Uinta Basin by Pantea (1987;1993) and Scott and Pantea (1990). The lake was confined for much of its history to the central part of the Piceance Basin, where the Cow Ridge Member reaches a maximum thickness of more than 2,200 ft, but expanded to occupy much of the basin during a comparatively short period of time (figs.…”

“…Included on figure 13 is the isopach map from the base of Paleocene to the base of the Long Point Bed in the Uinta and Piceance Basins and top of the Tipton Member. The freshwater lacustrine maximum is represented by the Uteland Butte member in the Uinta Basin, maximum transgression of the Cow Ridge Member in the Piceance Basin, and the Luman Tongue of the Green River Formation in the Greater Green River Basin (Roehler, 1993). During maximum transgression, the Uteland Butte and maximum Cow Ridge lake phases may have connected along the north part of the Douglas Creek arch where the Green River Formation is now eroded, because the two units can be traced to within a few miles of each other along the south part of the arch where the Green River Formation is still preserved.…”

Southwestward weakening of Wyoming lithosphere during the Laramide orogeny

2016

The mechanism of Laramide deformation in the central Rocky Mountains remains enigmatic. It is generally agreed that the deformation resulted from low‐angle subduction of the Farallon plate beneath the North American plate during the latest Cretaceous‐early Eocene; however, recent studies have suggested the importance of slab removal or slab rollback in causing this deformation. Here we infer Wyoming lithosphere structure and surface deformation pattern by conducting 2‐D flexural subsidence modeling in order to provide constraints on the mechanism of Laramide deformation. We assume that Wyoming lithosphere behaved as an infinite elastic plate subject to tectonic loading of mountain ranges and conduct 2‐D flexural subsidence modeling to major Laramide basins to document lithospheric stiffness and mountain load height. Our results show that the stiffness of Wyoming lithosphere varied slightly in each basin during the ~30 Myr duration of the Laramide deformation and decreased from northeastern Wyoming (Te = 32–46 km) to southwestern Wyoming (Te = 6–9 km). Our results also imply that the increase of equivalent load height of major Laramide ranges accelerated during the early Eocene. We propose that the bending stresses induced by the topographic load of the Sevier fold‐and‐thrust belt combined with crust‐mantle decoupling initiated by the overthickened Sevier hinterland and the end loads due to the low‐angle subduction at the western edge of the thick Wyoming craton have caused the southwestward decrease of lithospheric stiffness in Wyoming. Moreover, we attribute the accelerated load height gain during the early Eocene to both dynamic and isostatic effects associated with slab rollback.
