Late Paleozoic Structure of the Southern Part of the Uinta Basin, Utah, From Seismic Reflection Data (open access)

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

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 (open access)

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

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.

Mineral Resources of the Paria-Hackberry Wilderness Study Area, Kane County, Utah (open access)

Mineral Resources of the Paria-Hackberry Wilderness Study Area, Kane County, Utah

From abstract: The Paria-Hackberry Wilderness Study Area, in central Kane County, southern Utah, is a region of generally flat-lying, gently folded sedimentary rocks, bounded on the east by the east-dipping limb of the East Kaibab monocline and cut by sheer-walled, narrow canyons. The area selected for study by the U.S. Bureau of Land Management totaled 94,642 acres (148 square miles); because of uncertainty as to final boundaries, the U.S. Geological Survey studied an additional contiguous 41,180 acres (64 square miles).

Mineral Resources of the Sleeping Giant Wilderness Study Area, Lewis and Clark County, Montana (open access)

Mineral Resources of the Sleeping Giant Wilderness Study Area, Lewis and Clark County, Montana

From abstract: A mineral resource survey was conducted in 1987 by the U.S. Geological Survey and the U.S. Bureau of Mines to evaluate mineral resources (known) and mineral resource potential (undiscovered) of the Sleeping Giant Wilderness Study Area (MT-075-111) in Lewis and Clark County, Montana. The only economic resource in the study area is an inferred 1.35-million-ton reserve of decorative stone (slate); a small gold placer resource is subeconomic. A high resource potential for decorative slate exists directly adjacent to the area of identified slate resource and in the northeastern part of the study area. The rest of the study area has a low potential for decorative slate. The westernmost part of the study area has a moderate resource potential for copper and associated silver in strata-bound deposits in green beds and limestone; potential is low in the rest of the study area.

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

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

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.
