Environmental tritium in the Edwards Aquifer, central Texas 1963-71
Frederick Joseph Pearson, Paul L. Rettman, T.A. Wyerman
1975, Open-File Report 74-362
Tritium concentrations of samples from 50 wells and springs in the Edwards aquifer in the San Antonio area of Texas have been analysed. Tritium now in the aquifer is partly natural cosmic ray produced tritium, but most is tritium produced by atmospheric thermonuclear tests in the 1950's and early 1960's....

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...
Heavy mineral prospecting in Pakistan
Karl W. Stauffer, James Alfred Calkins
1975, Open-File Report 75-359
Heavy-mineral prospecting is a method of tracing potential ore minerals to their source by systematically examining the heavy minerals of stream sands. The heavy minerals are partially concentrated in the field by panning. In the laboratory the heavy minerals are further concentrated by floating off the quartz and feldspar in...
Ground-water investigation for U.S. Air Force Launch Control Facility O-O, Griggs County, North Dakota
G.L. Sunderland, Joe S. Downey
1975, Open-File Report 75-345
U.S. Air Force Launch Control Facility 0-0 is located about 3.6 miles (5.6 kilometres) north of Cooperstown, Griggs County, North Dakota. Test drilling indicates that a glacial-drift aquifer located within about 0.2 mile (0.3 kilometre) of the site will supply 2 to 3 gallons per minute (0.13 to 0.19 litre...

Ground water in the Grand (Neosho) River basin, Kansas and Oklahoma
Robert B. Morton, Stuart W. Fader
1975, Open-File Report 75-366
Ground water in the Grand (Neosho) River basin occurs in both consolidated rocks and unconsolidated deposits. Water for domestic and stock supplies generally can be obtained from wells in either of the above deposits. Water for municipal, industrial, and irrigation supplies generally can be obtained in limited quantities from the...

1975, Open-File Report 75-56
Several hydrothermal systems in northern and central Nevada were explored in a hydrogeologic reconnaissance. The systems studied comprise those at Stillwater and Soda Lakes-Upsal Hogback in the Carson Desert, Gerlach, Fly Ranch-Granite Range, and Double Hot Springs in the Black Rock Desert, Brady's Hot Springs, Leach Hot Springs in Grass...
Uranium in West Texas -- paper delivered June 3, 1975, AAPG-SEPM Rocky Mountain Section Meeting, Albuquerque, New Mexico

1975, Open-File Report 75-175
Anomalous amounts of tungsten, molybdenum, and bismuth were found previously in surficial debris collected from the Uyaijah-Thaaban area in the west-central part of the Precambrian Al Uyaijah ring structure. The area is mostly underlain by quartz monzonite. Countless quartz veins ranging from a knife edge to more than 3 m...

Hydrology for land-use planning: The Hillside area, Anchorage, Alaska
Larry L. Dearborn, William W. Barnwell
1975, Open-File Report 75-105
Rapid residential growth of the Hillside area, Anchorage, Alaska, may cause depletion of aquifers and a change in quality of water resources as a result of extensive development of small-lot tracts. Ground-water yields are low and may be locally inadequate for single family requirements where wells produce from bedrock in...
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...
