The Montezuma Creek-Aneth area is in the northeastern part of the Navajo Indian Reservation in southeastern Utah. It is a semiarid area along the San Juan River near the communities of Montezuma Creek and Aneth. Within the Blanding Basin, geologic formations exposed are of Jurassic and Quaternary age. The rock...
A program for mass spectrometer control and data processing analyses in isotope geology; written in BASIC for an 8K Nova 1120 computer
J. S. Stacey, J. Hope
1975, Open-File Report 75-127
A system is described which uses a minicomputer to control a surface ionization mass spectrometer in the peak switching mode, with the object of computing isotopic abundance ratios of elements of geologic interest. The program uses the BASIC language and is sufficiently flexible to be used for multiblock analyses of...

A model for earthquakes near Palisades Reservoir, southeast Idaho
David L. Schleicher
1975, Open-File Report 75-12
The Palisades Reservoir seems to be triggering earthquakes: epicenters are concentrated near the reservoir, and quakes are concentrated in spring, when the reservoir level is highest or is rising most rapidly, and in fall, when the level is lowest. Both spring and fall quakes appear to be triggered by minor...

Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-353
The area designated for possible oil and gas lease sale as modified from BLM memorandum 3310 #42 (722) and referred to therein as the North Atlantic Outer Continental Shelf (OCS) contains about 58,300 sq km of shelf beneath water depths of less than 200 m and lies chiefly within the...
In search of a statistical probability model for petroleum-resource assessment : a critique of the probabilistic significance of certain concepts and methods used in petroleum-resource assessment : to that end, a probabilistic model is sketched
Bernardo F. Grossling
1975, Circular 724
Exploratory drilling is still in incipient or youthful stages in those areas of the world where the bulk of the potential petroleum resources is yet to be discovered. Methods of assessing resources from projections based on historical production and reserve data are limited to mature areas. For most of the...
Water availability in Perry County, Alabama
Philip C. Reed, J.R. Willmon, Patrick O. Jefferson
1975, Open-File Report 75-482
The principal sources of large quantities of ground water in Perry County are sand and gravel aquifers in the Coker, Gordo, and Eutaw Formations of the Upper Cretaceous Series. Upper Cretaceous deposits, which dip to the southwest at about 35 feet per mile, range in thickness (d from about 400...
Hydrology and sedimentation of Bixler Run basin, central Pennsylvania
Lloyd A. Reed
1975, Open-File Report 75-26
Rainfall, streamflow, stream chemical, and sediment discharge data were collected from Bixler Run near Loysville, Pa., during the period February 1954 to September 1969, as part of a project to evaluate sediment discharge from an agricultural area that had been adopting soil-conservation techniques at a moderate rate. The study was...
Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1975, Open-File Report 75-13
A numerical model of a salt-wedge estuary developed by Fischer has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentrations, biochemical oxygen demand, and dissolved-oxygen concentrations in the Duwamish River estuary, King County, Wash. With this model, which was calibrated and verified with observed data,...
Reactions of aqueous aluminum species at mineral surfaces
David Wayne Brown, John David Hem
1975, Water Supply Paper 1827-F
Aqueous aluminum solutions containing 4.5 ? 10 4 molar aluminum in 0.01 molar NaC104 were partly neutralized with NaOH to give OH:A1 mole ratios from 1.40 to 2.76. Measured amounts of montmorillonite, kaolinite, volcanic ash, or feldspathic sand were added to provide an area of inert surface. Reactions that occurred...
Water availability of Washington County, Alabama
John G. Newton, Jerald F. McCain, James D. Turner
1975, Open-File Report 75-476
Large quantities of ground water and surface water are available in Washington County. Major sources of ground water are the Gosport Sand and Lisbon Formation undifferentiated, the Miocene Series undifferentiated, and alluvium and low terrace deposits. The Miocene, the most productive source of ground water, will yield 0.5 to 1.0...
Some reservoir engineering calculations for the vapor-dominated system at Larderello, Italy
Manuel Nathenson
1975, Open-File Report 75-142
Various reservoir properties are calculated for the Larderello vapor-dominated system using available published data. Bottom-hole flowing properties are calculated from measured wellhead data. Whereas wellhead temperatures measured at a particular time tend to change systematically with changes in flow and pressure, calculated bottom-hole temperatures tend to be constant for two...

1975, Open-File Report 75-312
County constitute the most extensive aquifers in the county. Four areally distinct sand and gravel aquifers were mapped in the drift during the course of this study. The aquifer of greatest economic importance consists of sand and gravel deposits of glacial-outwash origin which coincide with the courses of the White...

A digital-computer model for estimating drawdowns in the sandstone aquifer in Dane County, Wisconsin
R.S. McLeod
1975, Open-File Report 74-59
A digital-computer program was developed to compute nonsteady and steady-state hydrologic changes caused by pumping from a confined aquifer. The program computes head changes in the confined aquifer and the rate and volume of water withdrawn from aquifer boundaries.The program was used to model the sandstone aquifer underlying Dane County,...
Sandstone geometry, porosity and permeability distribution, and fluid migration in eolian system reservoirs
Robert Lupe, Thomas S. Ahlbrandt
1975, Open-File Report 75-357
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...
Hydrologic effects of reducing irrigation to maintain a permanent pool in John Martin Reservoir, Arkansas River Valley, Colorado
Richard R. Luckey
1975, Open-File Report 75-214
The U.S. Geological Survey has evaluated a plan by the Colorado Division of Wildlife to maintain a permanent pool of 10,000 acre-feet (1.2x107 cubic metres) in John Martin Reservoir on the Arkansas River. The proposed pool would be maintained through the use of water formerly diverted by the Catlin Canal...
Reconnaissance engineering geology of the Ketchikan area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard W. Lemke
1975, Open-File Report 75-250
The Alaska earthquake of March 27, 1964, dramatically emphasized the need for engineering geologic studies of urban areas in seismically active regions.

Stochastic analysis of particle movement over a dune bed
Baum K. Lee, Harvey E. Jobson
1975, Open-File Report 75-358
Stochastic models are available that can be used to predict the transport and dispersion of bed-material sediment particles in an alluvial channel. These models are based on the proposition that the movement of a single bed-material sediment particle consists of a series of steps of random length separated by rest...
