Facilities, National Institute of Standards and Technology

Description: From page 2: The National Institute of Standards and Technology research reactor is a national center for the application of reactor radiation to a variety of problems of national concern. Major program areas at the reactor include the application of neutron scattering methods to research in materials science, trace analysis by neutron activation, nondestructive evaluation (via neutron radiography and scattering), neutron standards and dosimetry , and isotope production and radiation effects.

Evolution of Sedimentary Basins--San Juan Basin: Chapters B-D

Description: From abstract: This report describes the depositional environments of the Chinle Formation that was deposited in a complex fluvial-deltaic-lacustrine system in the area of the present-day eastern San Juan basin and Chama basin. Lithofacies include conglomerate and planar- and trough-crossbedded sandstone; bentonitic mudstone and sandstone; black, organic carbon-rich mudstone; large-scale, trough crossstratified siltstone, sandstone, and mudstone; and thickbedded, bioturbated, fine-grained sands… more

[Evolution of Sedimentary Basins--Uinta and Piceance Basins: Chapters H and I]

Description: From abstract: Analysis of vitrinite reflectance profiles and surfaces of equal vitrinite reflectance in the southeastern part of the Piceance basin, northwestern Colorado, indicates that burial histories for the Divide Creek anticline and the Grand Hogback are different from those for adjacent synclines. These two positive structures probably reached their present-day thermal maturity before late Eocene folding and before the end of the Laramide orogeny. In contrast, adjacent synclines did not… more

Geologic History and Hydrocarbon Potential of Late Cretaceous-Age, Low-Permeability Reservoirs, Piceance Basin, Western Colorado

Description: From abstract: The Piceance basin of western Colorado contains large reserves of natural gas in low-permeability reservoirs of the Late Cretaceous-age Mesaverde Formation or Mesaverde Group. The gas accumulation can be divided into three general zones: a zone of surface-water invasion that extends inward a few miles from present outcrops, a gas-and-waterbearing zone that extends 10-20 miles inward from the water-bearing zone, and a central, predominantly gasbearing zone.

Mass Calibrations

Description: Abstract: The NIST calibration service for standard masses is described. Weights which are accepted for calibration range in nominal values from 1 mg to 13,600 kg (30,000 pounds). We also accept weights used to generate standard pressures in piston gages. Cleaning procedures used on weights prior to calibration are described. The measurement algorithms (including density determinations of single-piece kilogram weights) and the uncertainties assigned to calibrated weights are discussed. We also … more

Mineral Resources of the Bobcat Draw Badlands Wilderness Study Area, Big Horn and Washakie Counties, Wyoming

Description: Abstract: The Bobcat Draw (WY-010-126) Wilderness Study Area includes about 17,150 acres and is located about 45 mi (miles) by road west of Worland in the Bighorn basin. The arid landscape comprises treeless uplands drained by intermittent streams. No identified resources are in the Bobcat Draw Wilderness Study Area. Most of the area is currently under lease for oil and gas. The study area has a high potential for resources of oil and gas and a high potential for subeconomic resources of deeply… more

Mineral Resources of the Fish Springs Range Wilderness Study Area, Juab County, Utah

Description: Abstract: The Fish Springs Range Wilderness Study Area (UT-050-127) includes most of the Fish Springs Range and is located north of the House Range, about 50 miles northwest of the city of Delta, Utah. A mineral resource study of the 33,840-acre area was completed in 1987 by the U.S. Geological Survey and U.S. Bureau of Mines. The northwestern and southeastern parts of the wilderness study area contain inferred subeconomic resources of high-purity quartzite. No metallic mineral resources were i… more

Mineral Resources of the Indian Creek, Bridger Jack Mesa, and Butler Wash Wilderness Study Areas, San Juan County, Utah

Description: From abstract: The Indian Creek (UT-060-164), Bridger Jack Mesa (UT-060-167), and Butler Wash (UT-060-169) Wilderness Study Areas are located in San Juan County, southeastern Utah. Inferred subeconomic resources of sandstone and sand and gravel exist within all three wilderness study areas, but because of their abundance throughout the region, their distance from current markets, and their lack of unique properties, these materials have no current likelihood for development.

Mineral Resources of the Medicine Lodge, Alkali Creek, and Trapper Creek Wilderness Study Areas, Big Horn County, Wyoming

Description: From introduction: This report presents an evaluation of the mineral endowment (identified resources and mineral resource potential) of the study area and is the product of several separate studies by the U.S. Bureau of Mines (USBM) and the U.S. Geological Survey (USGS). Identified resources are classified according to a modification of the system described by McKelvey (1972) and the USBM and USGS (1980), which is shown in the Appendix. Identified resources are studied by the USBM. Mineral reso… more
