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.

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.

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.

Facies Analysis, Genetic Sequences, and Paleogeography of the Lower Part of the Minturn Formation (Middle Pennsylvanian), Southeastern Eagle Basin, Colorado

Description: From abstract: Siliciclastic and minor carbonate rocks of the lower part of the Middle Pennsylvanian Minturn Formation of north-central Colorado were deposited in alluvial-fan, braidplain, Gilbert-delta, shoreline, and paralic, and offshore-marine environments. These strata can be divided into twelve genetic sequences that are generally bounded by transgressive surfaces of erosion or paralic flooding surfaces, and are characterized by thin and thick transgressive units. This report examines the… more

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.

Stratigraphy of the Mississippian System, South-Central Colorado and North-Central New Mexico

Description: From abstract: In the Sawatch, Mosquito and Front Ranges of central Colorado and the Sangre de Cristo Mountains of south-central Colorado, Tournaisian beds of the Mississippian Leadville Limestone overlie rocks of Early Mississippian and Late Devonian age. In the Sangre de Cristo Mountains in north-central New Mexico, the oldest beds are the Tournaisian (zone 9) Espiritu Santo Formation. In west-central New Mexico, in the Magdalena, Lemitar, and Ladron Mountains, the Kelly Limestone of Tournais… more

Stratigraphy of the Eocene Part of the Green River Formation in the South-Central Part of the Uinta Basin, Utah

Description: From abstract: Seventeen stratigraphic sections totalling 4,514.3 m were investigated and previous reports studied in order to clarify and illustrate the stratigraphy of most of the Eocene part of the fluvial and lacustrine Green River Formation in the south-central part of the Uinta basin of Utah.
