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.

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 Tournaisian and Visean age rests unconformably on Proterozoic metamorphic and igneous rocks. This report examines the stratigraphy of this area.

Structure and Stratigraphy of Upper Cretaceous and Paleogene Strata (North Horn Formation), Eastern San Pitch Mountains, Utah: Sedimentation at the Front of the Sevier Orogenic Belt

Description: From abstract: This report describes the North Horn Formation in the eastern part of the San Pitch Mountains of Utah was deposited in nonmarine environments that included alluvial fans, varied fluvial and overbank settings, and lacustrine settings.

Subdivision, Subsurface Stratigraphy, and Estimated Age of Fluvial-Terrace Deposits in Northwestern Tennessee

Description: This report studies the fluvial-terrace deposits in northwestern Tennessee with the intention of establishing a means of correlating disjunct terrace segments along the Obion River that is independent of terrace height, to document the stratigraphy of selected terrace deposits, and to estimate their numerical ages.

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.

Whistle, a Nearly Dormant Geyser in Upper Geyser Basin, Yellowstone National Park, Wyoming: The First Geyser to be Studied by Research Drilling

Description: The following report follows the first research drilling study on a geyser. Whistle, a nearly dormant geyser in the upper geyser basin in Yellowstone National Park, Wyoming, has been proven to depend its water supply on deep overpressured water that's a far more extensive system than surface measurements can determine.
