Reconnaissance for uranium and thorium in Alaska, 1954
John J. Matzko, Robert G. Bates
1957, Trace Elements Investigations 611
During 1954 reconnaissance investigations to locate minable deposits of uranium and thorium in Alaska were unsuccessful. Areas examined, from which prospectors had submitted radioactive samples, include Cap Yakataga, Kodiak Island, and Shirley Lake. Unconcentrated gravels from the beach at Cape Yakataga average about 0.001 percent equivalent uranium. Uranothorianite has been...
Lead-alpha age determinations of granitic rocks from Alaska
John J. Matzko, H.W. Jaffe, C. L. Waring
1957, Trace Elements Investigations 618
Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part...
Summary of reconnaissance for uranium in Alaska, 1955
John J. Matzko, Val L. Freeman
1957, Trace Elements Investigations 617
Reconnaissance for uranium in Alaska during 1955 included airborne radiometric traverses, examination of radioactivity anomalies found during the airborne traverses, examination of prospector leads, and examination of areas that seems geologically favorable for the occurrence of uranium. The airborne radiometric traverses in central Alaska revealed 33 anomalies considered worth examining....
Glacial features and surficial deposits of the Malaspina district, Alaska
George Plafker, Don John Miller
1957, Open-File Report 57-91
The Malaspina district extends about 50 miles along the north shore of the Gulf of Alaska from Icy Bay and the Guyot Glacier on the west to Yakutat Bay and Disenchantment Bay on the east (see index map). The district includes a coastal lowland flanked on the north by a...
Geology of possible petroleum provinces in Alaska
Don John Miller, Thomas G. Payne, George Gryc
1957, Open-File Report 57-72
The history of petroleum exploration in Alaska and the geology of possible petroleum provinces in Alaska are reviewed. Maps showing Alaska's major Mesozoic and Tertiary tectonic elements, possible petroleum provinces, and indications of petrol, are included in this report. Annotated references in Geological Survey publications relating to petroleum and oil...
Water problems in the present trend towards greater aridity
Luna Bergere Leopold
Harmon Craig, editor(s)
1957, Conference Paper, Proceedings: Conference on recent research in climatology
In the past few days we have heard a number of scientists, gathered here at Scripps Institution of Oceanography, discuss research work which, in one manner or another, bears on problems related to water resources. They have been discussing, particularly, problems in the field of climatology, and have speculated on...
