Reconnaissance of the hydrothermal resources of Utah
F. Eugene Rush
1983, Professional Paper 1044-H
Geologic factors in the Basin and Range province in Utah are more favorable for the occurrence of geothermal resources than in other areas on the Colorado Plateaus or in the Middle Rocky Mountains. These geologic factors are principally crustal extension and crustal thinning during the last 17 million years. Basalts...
Geoelectric structure of the Gila-San Francisco Wilderness Area, Graham and Greenlee Counties, Arizona, from audio-magnetotelluric data
D. P. Klein, M. J. Baer
1983, Open-File Report 83-815
Electromagnetic induction data using distant field sources, mostly of natural origin, in the frequency range of 4.5-27,000 Hz are analyzed to depict the geoelectric structure in an area of volcanic-rock cover located in southeastern Arizona between the Morenci and Safford porphyry copper deposits. The data for each station consist of...

Mineral potential of selected felsic plutons in the eastern and southeastern Arabian Shield, Kingdom of Saudi Arabia
Edward A. du Bray
1983, Open-File Report 83-370
Sixteen well-defined geochemical anomalies associated with felsic plutons and (or) muscovite-bearing plutons of Proterozoic age have been identified in the eastern and southeastern Arabian Shield. The majority of these plutons are highly evolved, granitophile-element-enriched muscovite-bearing granites that are weakly peraluminous. A followup study of the mineral potential of these plutons included...

Effects on water quality of coal mining in the basin of the North Fork Kentucky River, eastern Kentucky
Kenneth L. Dyer
1983, Water-Resources Investigations Report 81-215
A study of the effects on water quality of coal mining in the basin of the North Fork Kentucky River shows increases in the mean annual total dissolved solids concentrations from about 8 to 50 milligrams per liter. It shows that the Hazard Number 9 coal seam produces the largest...

Preliminary report on near-surface lignite occurrences, Cleveland County, Arkansas
Stephen E. Heermann
1983, Open-File Report 83-53
Four cross sections were constructed from lithologic descriptions of 43 drill holes in Cleveland County, Ark., in order to illustrate the occurrence of lignite and to relate the lignite beds to the regional stratigraphic framework. Of 43 holes drilled, 8 contained beds of lignite, but only two had beds greater...

Paleomagnetic results from seven middle Paleozoic plutons in the Appalachian Piedmont of North and South Carolina
J.T. Hagstrum
1983, Open-File Report 83-916
Seven isotopically dated plutons of similar middle Paleozoic age (approx. 400 Ma) were sampled for paleomagnetic study. The results from 12 sites (152 samples) within these plutons show two types of remanence behavior that appear fairly consistent with rock composition. The more leucocratic rocks (9 sites) tend to yield single-component...
