Mines, prospects, and occurrences map of the Seward and Blying Sound quadrangles, Alaska
Russell G. Tysdal
1978, Miscellaneous Field Studies Map 880-A
The Prince William Sound region may be considered as made up of two extensive and distinctive mineral belts defined by the preponderance of either gold or copper deposits (Capps and Johnson, 1915). In the Seward and Blying Sound quadrangles, the division of the two belts is approximately along the Contact...
Stamukhi shoals of the Arctic - some observations from the Beaufort Sea
Erk Reimnitz, Douglas K. Maurer
1978, Open-File Report 78-666
A number of linear shoals, representing pronounced topographic anomalies on the surface of the Arctic shelf, have been studied in the Prudhoe Bay area. These shoals have been referred to in several previous studies. Based on seismic reflection records, Reimnitz et al., (1972a), stated that the shoals are constructional features...
Surface water records of Cook Inlet basin, Alaska, through September 1975
David R. Scully, Larry S. Leveen, Raymond S. George
1978, Open-File Report 78-498
This report summarizes records of streamflow and water temperature collected prior to October 1, 1975, in the Cook Inlet Basin of south-central Alaska. Streamflow records for gaging stations are tabulated as monthly and annual summaries and annual extremes. For those gaging stations at which continuous or daily water temperature records...
Contact-metasomatic magnetite deposit, Medfra Quadrangle, Alaska
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...
Effects of permafrost on stream channel behavior in Arctic Alaska
Kevin M. Scott
1978, Professional Paper 1068
Sites with drainage areas ranging from 88 to 12,200 sq km were monitored on five streams in northern Alaska during the breakup in 1976 to determine (1) the effects of frozen bed and bank material on channel behavior, and (2) the importance of the annual breakup flood in forming the...
The Energy Lands Program of the U.S. Geological Survey, fiscal year 1976
John O. Maberry (compiler)
1978, Circular 778
The Energy Lands Program of the U.S. Geological Survey comprises several projects that conduct basic and interpretive earth-science investigations into the environmental aspects of energy-resource recovery, transmission, and conversion. More than half the coal reserves of the United States occur west of the Mississippi River; therefore, the program concentrates mostly...
Hydrologic information for land-use planning, Fairbanks vicinity, Alaska
Gordon L. Nelson
1978, Open-File Report 78-959
The flood plain on the Chena and Tanana Rivers near Fairbanks, Alaska, has abundant water in rivers and in an unconfined alluvial aquifer. The principal source of ground water is the Tanana River, from which ground water flows northwesterly to the Chena River. Transmissivity of the aquifer commonly exceed 100...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Craig Quadrangle, Alaska
Edward Huntington Cobb
1978, Open-File Report 78-869
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Craig quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
