Soil anomalies associated with Cu-Ni mineralization in the South Kawishiwi area, northern Lake County, Minnesota
Henry V. Alminas
1975, Open-File Report 75-158
Geochemical sampling in the contact zone between the Giants Range Granite and the Duluth Gabbro Complex along the South Kawishiwi River indicates the presence of extensive soil anomalies associated with the known Cu-Ni-Co-Ag mineralization in the basal part of the Duluth Gabbro Complex. A close spatial relationship was found between...
A Study of earthquake losses in the Puget Sound, Washington, area
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-375
The Puget Sound Basin has a history of frequent seismic activity, including two recent damaging events. The greatest extent of urban development and the most densely populated area generally correspond to the area where the greatest energy release has been experienced. For this study two earthquakes have been simulated, each...
A summary of relative ages of lunar nearside and farside plains
Joseph M. Boyce, Arthur L. Dial, Laurence A. Soderblom
1975, Open-File Report 75-141
This report contains a summary of the moon-wide distribution of relative ages of lunar plains units determined with Apollo and Lunar Orbiter photographs. Relative ages are expressed as the largest diameter of craters (DL, meters) in a mappable unit that are eroded to a slope of 1° by the net...
Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas
Josephine G. Boerngen, George Van Trump, Richard J. Ebens
1975, Open-File Report 75-137
This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas. The primar object of the study was to assess scale-related components of geochemical variance with...
Reconnaissance study of sediment transport by selected streams in the Yakima Indian Reservation, Washington, 1974 water year
Philip Richard Boucher
1975, Open-File Report 75-67
This was a reconnaissance study for information on suspended-sediment concentrations and basin yields at 21 sites on selected streams in the Yakima Indian Reservation in Washington, and two sites on nearby streams. Suspended-sediment yields were generally low relative to those indicated by data for other streams on southeastern Washington, the...
Hydrology of three sinkhole basins in southwestern Seminole County, Florida
Warren Anderson, G.H. Hughes
1975, Open-File Report 75-27
The southwestern part of Seminole County--in east-central Florida-is characterized by sinkholes formed by the subsidence of surficial deposits into solution cavities in the underlying limestone deposits. The area includes three sinkhole basins created by such subsidence: Cranes Roost, Palm Springs, and Grace Lake.Cranes Roost basin (drainage area, 5.02 square miles)...

Physical factors determining the fraction of stored energy recoverable from hydrothermal convection systems and conduction-dominated areas
Manuel Nathenson
1975, Open-File Report 75-525
This report contains background analyses for the estimates of Nathenson and Muffler (1975) of geothermal resources in hydrothermal convection systems and conduction-dominated areas. The first section discusses heat and fluid recharge potential of geothermal reservoirs. The second section analyzes the physical factors that determine the fraction of stored energy obtainable...

Geology of the Midnite uranium mine, Stevens County, Washington; a preliminary report
J. Thomas Nash, Norman J. Lehrman
1975, Open-File Report 75-402
The Midnite mine is one of only two mines in the United States currently producing uranium from discordant deposits in crystalline host rocks. Ore bodies are in metamorphosed steeply dipping Precambrian pelitic and calcareous rocks of a roof pendant adjacent to a Cretaceous(?) porphyritic quartz monzonite pluton. Production during 14...

Surface current observations--Beaufort Sea, 1972
Peter Barnes, Richard Garlow
1975, Open-File Report 75-619
Sediment transport via water and ice in the Beaufort Sea off northern Alaska is related to the movement of the surficial waters. As development proceeds along the north slope of alaska, a knowledge of the potential drift trajectories of water, ice, sediment and pollutants will be needed. In an attempt...

Sulfur, fluorspar, magnesite, and aluminous chromite in Pakistan
Raymond H. Nagell
1975, Open-File Report 75-496
Reports and analyses on elemental sulfur, fluorspar, magnesite, and aluminous chromite were reviewed for the purpose of identifying and categorizing the known deposits, and to indicate those which seem to merit further study on the basis of available information. General conclusions drawn from the study are: (1) Although aluminous chromite...

Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
