Availability of ground water in Marion County, Indiana
William R. Meyer, J. P. Reussow, D. C. Gillies, W. J. Shampine
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...
Seismic refraction records from a survey in the Gulf of Alaska

1975, Open-File Report 75-283
In September, 1974, the U.S. Geological Survey conducted a seismic refraction survey between Icy Bay and Kayak Island in the Gulf of Alaska to measure the seismic velocity and thickness of the sedimentary section. The purpose of this report is to make the original field records publicly available. Five lines...

A reconnaissance study of the U and Th contents of plutonic rocks of the southeastern Seward Peninsula, Alaska
Thomas P. Miller, Carl M. Bunker
1975, Open-File Report 75-217
Large granitic Cretaceous plutons are exposed along and adjacent to an arcuate belt of igneous and high-grade metamorphic rocks in the southeastern Seward Peninsula of Alaska. Reconnaissance studies of these plutons have shown that the Darby pluton has well above average amounts of U and Th (11.2 ppm and 58.7...
U, Th, and K analyses of selected plutonic rocks from west-central Alaska
Thomas P. Miller, Carl M. Bunker
1975, Open-File Report 75-216
Numerous samples of plutonic rocks collected during reconnaissance mapping in western Alaska have been analyzed for K, U, and Th. The U and Th content of the plutonic rocks from the southeastern Seward Peninsula have been discussed in a separate report (Miller and Bunker, 1975); because of the current interest...

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...

Reconnaissance of the geology and ore mineralization in part of the Chagai District, Pakistan
Raymond H. Nagell
1975, Open-File Report 75-550
The Chagai District of the Quetta Division is in the northwestern part of Pakistan. Igneous activity during the Himalayan orogeny included the extrusion of horizontally layered andesites of the Cretaceous Sinjrani Volcanic Group, emplacement of monzonitic stocks of the Cretaceous Chagai intrusions, and the extrusion of flows and tuffs of the...
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...

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...

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...
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...
