Geologic setting and chemical characteristics of hot springs in central and western Alaska
Thomas P. Miller, Ivan Barnes, William Wallace Pattan Jr.
1973, Open-File Report 73-188
Numerous hot springs occur in a variety of geologic provinces in central and western Alaska. Granitic plutons are common to all the provinces and the hot springs are spatially associated with the contacts of these plutons. Of 23 hot springs whose bedrock geology is known, all occur within 3 miles...
United States Geological Survey Alaska program, 1973
Water Resources Division, U.S. Geological Survey
1973, Circular 683
This report on the Alaskan activities of the U.S. Geological Survey contains up-to-date accounts of recent results and summaries of plans for the summer of 1973. It is organized in six parts: (1) responsibilities and services of the Geological Survey; (2) organization of the U.S. Geological Survey; (3) Alaskan field...
Index of metallic mineral deposits of Alaska compiled from reports in open files of the U.S. Geological Survey and U.S. Bureau of Mines through 1972
Edward H. Cobb
1973, Open-File Report 73-47
This index supplements a similar index of published reports (Cobb, 1973) currently being processed for formal publication. Inasmuch as many open-file reports are preliminary and eventually superseded by final published reports, it is inappropriate to include references to open-file reports in a permanent index. As most preliminary reports are of...
Stratigraphy and geologic history of the Montana group and equivalent rocks, Montana, Wyoming, and North and South Dakota
James R. Gill, William Aubrey Cobban
1973, Professional Paper 776
During Late Cretaceous time a broad north-trending epicontinental sea covered much of the western interior of North America and extended from the Gulf of Mexico to the Arctic Ocean. The sea was bounded on the west by a narrow, unstable, and constantly rising cordillera which extended from Central America to...
Measurement of lateral erosion at proposed river crossing sites of the Alaskan pipeline
James Brice
1973, Open-File Report 73-31
This study of lateral erosion rates by comparison of aerial photographs was undertaken at the request of D. M. Culbertson, hydraulic engineer, U.S. Geological Survey, Menlo Park, Calif., and preparatory work in Alaska (during June 1-18, 1971) was done with the cooperation of Harry Hulsing, district chief, Alaska District. Examination...
Radioelement distribution in the basement complex of the Yukon-Tanana upland, Eielson deep test hole, Alaska
C. M. Bunker, C. A. Bush, R. B. Forbes
1973, Journal of Research of the U.S. Geological Survey (1) 659-663
Uranium, thorium, and potassium contents were determined in 94 samples of drill cuttings from a 9,774-foot-deep exploratory hole drilled entirely in crystalline schists of the basement complex of the Yukon-Tanana Upland. The data indicate two distinctively different rock types and reflect differences in the calcite content of the rock. Zones of anomalously high concentrations of...
