Hot, deep origin of petroleum: deep basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1020
Use of the model of a hot deep origin of oil places rigid constraints on the migration and entrapment of crude oil. Specifically, oil originating from depth migrates vertically up faults and is emplaced in traps at shallower depths. Review of petroleum-producing basins worldwide shows oil occurrence in these basins...

M.L. Throckmorton, William Wallace Patton
1978, Open-File Report 78-26
A small contact-metasomatic magnetite deposit was discovered in the Medfra quadrangle, Alaska, in 1976. It occurs at the contact between a Cretaceous or early Tertiary quartz monzonite stock and Paleozoic limestone and dolomite. The ore is a magnetite-clinohumite-hematite rock that contains up to 60 volume percent magnetite and 76 weight...

James V. Taranik
1978, Open-File Report 78-187
Landsat satellites were launched into orbit in 1972 and 1975. Additional Landsat satellites are planned for launch in 1978 and 1981. The satellites orbit the Earth at an altitude of approximately 900 km and each can obtain repetitive coverage of cloud-free areas every 18 days. A sun-synchronous orbit is used...
Summary appraisals of the Nation's ground-water resources; Alaska
Chester Zenone, Gary S. Anderson
1978, Professional Paper 813-P
Alaska has enormous surface-water resources, but many of the streams are frozen for most of the year and most contain glacial silt that makes them unacceptable for human use. These factors lend special significance to ground water as a water-supply source, even though perennially frozen ground (permafrost) profoundly modifies ground-water...

S.L. Stockton, Alfred H. Balch
1978, Open-File Report 78-591
The Salt Valley anticline, in the Paradox Basin of southeastern Utah, is under investigation for use as a location for storage of solid nuclear waste. Delineation of thin, nonsalt interbeds within the upper reaches of the salt body is extremely important because the nature and character of any such fluid-...

Potential effects of deep-well waste disposal in western New York
Roger Milton Waller, John T. Turk, Robert James Dingman
1978, Professional Paper 1053
Mathematical and laboratory models were used to observe, respectively, the hydraulic and chemical reactions that may take place during proposed injection of a highly acidic, iron-rich waste pickle liquor into a deep waste-disposal well in western New York. Field temperature and pressure conditions were simulated in the tests. Hydraulic pressure...
Determination of peak discharge from rainfall data for urbanized basins, Wichita, Kansas
C.O. Peek, P. R. Jordan
1978, Open-File Report 78-974
Rainfall and runoff data from urbanized drainage basins in the Wichita area, Kansas, were used to evaluate the Soil Conservation Service synthetichydrograph method of computing flood hydrographsfrom rainfall data. The method was tested on six basins where the impervious surface ranged from 11 percent on the least urbanized basin to...
Suspended-sediment transport in the Big Eau Pleine River Basin, central Wisconsin

1978, Open-File Report 78-313
Suspended-sediment yields in the Big Eau Pleine River basin are low to moderate in comparison with other drainage basins in Wisconsin. Average annual yield in the Big Eau Pleine River near Stratford is 32.tons per square mile, with an annual yield ranging from 1.0 to 64 tons per square mile....

Unsteady solute-transport simulation in streamflow using a finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-18
This report documents a rather simple, general purpose, one-dimensional, one-parameter, mass-transport model for field use. The model assumes a well-mixed conservative solute that may be coming from an unsteady source and is moving in unsteady streamflow. The quantity of solute being transported is in the units of concentration. Results are...
