Data from geologic investigations in the Yemen Arab Republic during 1976
Maurice J. Grolier, J. A. Domenico, Mary Donato, G. Chase Tibbitts Jr., W.C. Overstreet, Mohammad Mukred Ibrahim
1977, Open-File Report 77-733
The results of semiquantitative spectrographic analyses for 31 elements in 126 specimens of rocks from the Yemen Arab Republic, collected mainly during February 1976 from the Precambrian area in the southeastern part of the country, provide background data for use in geochemical evaluation of areas potentially favorable for mineral deposits....

Hydraulic analysis, Mad River at State Highway 41, Springfield, Ohio
Ronald I. Mayo
1977, Open-File Report 77-399
A hydraulic analysis of the lad River in a reach at Springfield, Ohio was made to determine the effects of relocating State Highway 41 in 1S76. The main channel was cleaned by dredging in the vicinity cf the new highway bridge and at the Detroit, Toledo and Ironton Railway bridge...
Finite-difference model of two-dimensional, single, and two-phase heat transport in a porous medium - Version I
Charles R. Faust, James W. Mercer
1977, Open-File Report 77-234
Model documentation is presented for a two-dimensional (areal) heat-transport model capable of simulating both water- and vapor-dominated geothermal reservoirs that conform with the assumptions of the model. Finite-difference techniques are used to solve for the dependent variables pressure and enthalpy. The program is designed to simulate time-dependent problems such as...
A theoretical analysis of fluid flow and energy transport in hydrothermal systems
Charles R. Faust, James W. Mercer
1977, Open-File Report 77-60
A mathematical derivation for fluid flow and energy transport in hydrothermal systems is presented. Specifically, the mathematical model describes the three-dimensional flow of both single- and two-phase, single-component water and the transport of heat in porous media. The derivation begins with the point balance equations for mass, momentum, and energy....

Progress report on uranium investigations in the Zane Hills area, west-central Alaska
Thomas P. Miller, Raymond L. Elliott
1977, Open-File Report 77-428
The Zane Hills pluton underlies a mountainous area of about 460 km2 in west-central Alaska and is locally enriched in uranium and thorium (Miller and Ferrians, 1968; Miller, 1970; Staatz and Miller, 1976). While over 90 percent of the pluton consists of granodiorite with average contents of uranium and thorium,...
Quality of rivers of the United States, 1974 water year: based on the National Stream Quality Accounting Network (NASQAN)
Richard O. Hawkinson, John F. Ficke, L.G. Saindon
1977, Open-File Report 77-151
The National Stream Quality Accounting Network (NASQAN) was established by the U.S Geological Survey to determine and compare the quality at key locations on the Nation 's major rivers. There are 345 stations in the network--data from the first 101 of these (those operating during the 1974 water year) are...

Surface sedimentary units of the Gulf of Alaska continental shelf: Montague Island to Yakutat Bay
Bruce F. Molnia
1977, Open-File Report 77-30
Four major sedimentary units occur on the sea floor of the continental shelf in the northern Gulf of Alaska. These units, defined on the basis of seismic and sedimentologic data, are: (1) Holocene sediments, (2) Holocene mind moraines, C3) Quaternary glacial marine sediments, and (4) Tertiary and Pleistocene lithified deposits. A...
Digital model of the Arikaree Aquifer near Wheatland, southeastern Wyoming
Dwight T. Hoxie
1977, Open-File Report 77-676
A digital model that mathematically simulates the flow of ground water, approximating the flow system as two-dimensional, has been applied to predict the long-term effects of irrigation and proposed industrial pumping from the unconfined Arikaree aquifer in a 400 square-mile area in southeastern Wyoming. Three cases that represent projected maximum,...
