The Frontier Formation and Associated Rocks of Northeastern Utah and Northwestern Colorado

Description: From abstract: The Frontier Formation of the Mancos Group in northeastern Utah and northwesternmost Colorado (proposed new rank designations; formerly known as the Frontier Sandstone Member of the Mancos Shale) consists of several facies of marine and nonmarine rocks of Late Cretaceous (Turonian) age that grade eastward into totally marine rocks in easternmost Utah and northwestern Colorado.

Late Paleozoic Structure of the Southern Part of the Uinta Basin, Utah, From Seismic Reflection Data

Description: From abstract: Seismic reflection data from the southern part of the Uinta basin near Price, Utah reveal a network of late Paleozoic faults that produced abrupt variations in stratigraphic thicknesses in a structurally complex 30-mi-wide northwest-southeast-trending trough.

Middle Cretaceous Stratigraphy on the South and East Sides of the Uinta Basin, Northeastern Utah and Northwestern Colorado

Description: From abstract: Middle Cretaceous rocks (Aptian to Coniacian) on the south side of the Uinta Basin include the nonmarine Cedar Mountain Formation and Dakota Sandstone and the lower part of the overlying marine Mancos Shale. This report examines the rocks contained within this area of the basin.

Surface Vitrinite Reflectance Study of the Uinta and Piceance Basins and Adjacent Areas, Eastern Utah and Western Colorado: Implications for the Development of Laramide Basins and Uplifts

Description: From abstract: A study of mean random vitrinite reflectance of surface and near-surface samples was conducted in western Colorado and eastern Utah in order to better understand the subsidence and thermal histories of the Laramide-age Uinta and Piceance basins and to estimate the the thickness of overburden removed from the two basins. The history of uplift on some of the adjacent Laramide uplifts were also studied.
