As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 18 samples were collected from the Upper Cretaceous Emery and Ferron Sandstone Members of the Mancos Shale in the Henry Mountains coal field, Wayne and Garfield Counties, Utah (fig....

The southern Powder River area comprises about 2,230 square miles in southeastern Montana. Sedimentary rocks beneath this area range in age from Cambrian to Holocene and attain a maximum thickness of about 12,000 feet. Rocks exposed in the study area range in age from Late Cretaceous to Holocene.Water for domestic,...

This report summarizes and makes available to other investigators the measured hydraulic data collected during a series of experiments designed to study the effect of patterned bed roughness on steady and unsteady open-channel flow. The patterned effect of the roughness was obtained by clear-cut mowing of designated areas of an...

Water-quality data for the Hanna and Carbon Basins, south-central Wyoming, are presented in tables with no interpretation. Common-constituent, trace-element, and radiochemical data for ground and surface water and sediment concentrations for surface water are included. Ground water at 53 sites and surface water at 3 gaging stations were sampled. (Kosco-USGS)...

The rock formations of the John Day Fossil Beds National Monument area are aquifers that can be expected to yield less than 10 gallons of water per minute to wells. The most permeable of the geologic units is the alluvium that occurs at low elevations along the John Day River...

Ground-water data for the Baker County-northern Malheur area, Oregon, are tabulated for the Bureau of Land Management. The data include well and spring records, a well-location map, drillers' logs of wells, observation-well hydrographs, and chemical analyses of ground-water samples. The reported yields of wells and springs in the area ranged...

This report is a summary of the principal objectives, results, and conclusions of the environmental studies conducted by the U. S. Geological Survey (USGS) in the Baltimore Canyon Trough area from July 1, 1975 to June 30, 1976. Environmental studies in the Baltimore Canyon Trough area were funded by the...

A slingram geophysical survey was made in early 1978 as part of the integrated geologlcal-geophysical study aimed at evaluating the Eleana Formation as a possible repository for nuclear waste. The slingram data were taken over an alluvial fan and pediments along the eastern flank of Syncline Ridge about 45 km...

An airborne gamma-ray spectrometer survey covering 2750 km2 in the Jabal Sayid area, Kingdom of Saudi Arabia, was flown to measure anomalous concentrations of potassium in a known mineral belt. No anomalies were detected over the Jabal Sayid copper prospect, although part of the prospect is within a radioactive, high-dispersion...

Data are presented on the quantitative relations between water chemistry and phytoplankton productivity in San Francisco Bay between March 1976 and July 1977. Spatial distributions are listed for: salinity, temperature, transmission, chlorophyll-a, fluorescence, dissolved oxygen, orthophosphate, nitrate + nitrite, nitrite, ammonia, particulate organic carbon, alkalinity, pH, pCO2, suspended sediment and...

The major thrusts of investigations of the use of space data for understanding our Earth continue to focus on the land and near-shore environments. This is expectable; people live on the land, draw most of their resources from the land or near-shore areas, and in these areas environmental degradation or...

The core was collected from ponded sediment near the crest of a diapir-like feature on the Eel Plateau. The measured hydrocarbons are likely to have been derived from deep in the Neogene sedimentary section of the Eel River Basin. Their presence at the surface may indicate migration along fractures in...

Ground water in and near a proposed landfill site can become contaminated by leachates from the fill material. Realizing that potential, Pinellas County entered into a cooperative investigation with the U.S. Geological Survey to determine background water-quality conditions, and to evaluate the potential effects of landfill leachate on the quality...

Radium and uranium concentrations in water from 37 wells tapping the aquifer system of the Dakota Sandstone and Purgatoire Formation in southwestern Pueblo County, Colorado, have a wide range of values and define several areas of high radioactivity in the ground water. Radium ranges from 0.3 to 420 picocuries per...

Data on the East Fork Des Moines River for the August 1979 flood between river miles 330.4 and 408.8 is being published as a supplement to the report "Floods in the Upper Des Moines River basin, Iowa" (Schwab, 1970). Elevation profiles of the 1979 flood, along with previously published profiles, are shown in figures...

These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Valdez quadrangle, Alaska. All references to most reports of the Geological Survey, the U.S. Bureau of Mines, and the State of Alaska Division of...

The Najd fault system is a major transcurrent (strike-slip) fault system of Proterozoic age in the Arabian Shield. The system is a braided complex of parallel and curved en echelon faults. Complex arrays of secondary structures including strike-slip, oblique-slip, thrust, and normal faults, together with folds and dike swarms, are...
