Authigenic kaolinite and associated pyrite in chalk of the Cretaceous Niobrara Formation, Eastern Colorado
R. M. Pollastro
1981, Journal of Sedimentary Petrology (51) 553-562
Cores from the Smoky Hill Chalk Member of the Cretaceous Niobrara Formation have several zones containing authigenic kaolinite as spherical, moldic, polycrystalline aggregates that occur within single or multichambered foraminiferal tests and are commonly associated with framboidal pyrite. Such kaolinite is inferred to result from volcanic ash deposited during chalk...
K-Ar ages on intrusive and altered zones in the Chignik and Sutwik Island quadrangles: A section in The United States Geological Survey in Alaska: Accomplishments during 1979
Frederic H. Wilson
1981, Report, The United States Geological Survey in Alaska: Accomplishments during 1979 (Circular 823-B)
Continued K-Ar dating of intrusive rocks and hydrothermal alteration zones in the Chignik and Sutwik Island quadrangles of the Alaska Peninsula, supplemental to that by Wilson, Detterman, and Silberman (1978) and Wilson (1978), has refined our knowledge of the ages of the igneous rocks and clarified relations between altered zones...
Designation of principal water-supply aquifers in Minnesota
D. G. Adolphson, J. F. Ruhl, R. J. Wolf
1981, Water-Resources Investigations Report 81-51
Fourteen aquifers, ranging from Quaternary to Precambrian in age, have been identified as the principal sources of water to wells in Minnesota. Half the municipal population anc nearly all the rural population depend on water from these aquifers. Buried and surficial sand and gravel aquifers of Quaternary age occur in...
Water type and suitability of Oklahoma surface waters for public supply and irrigation, Part 3: Canadian, North Canadian, and deep fork river basins through 1979
Jerry D. Stoner
1981, Water-Resources Investigations Report 81-80
Water-quality data through 1979 in the Canadian, North Canadian, and Deep Fork River basins within Oklahoma were examined for water type and suitability for public water supply and irrigation use. Of 105 stations with available data, 47 stations or 45 percent were considered to have sufficient data for analysis. The...
Two oil types on North slope of Alaska: Implications for exploration
L. B. Magoon, George E. Claypool
1981, American Association of Petroleum Geologists Bulletin (65) 644-652
Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age and...
Preliminary observations on the Campania-Basilicata, Italy, earthquake of November 23, 1980
J. L. Stratta, L. E. Escalente, E.L. Krinitzsky, U. Morelli
1981, Earthquake Information Bulletin (USGS) (13) 18-22
The authors comprised a field study team sent by the Earthquake Engineering Research Institue (EERI) and the National Research Council (NRC) of the United States to make a reconnaissance study of the earthquake in southern Italy. The team members were selected for their experience and expertise and served the EERI...
