Analyses of rock and stream-sediment samples from the Sumdum A-3 Quadrangle, Alaska
Allen L. Clark, David A. Brew, Donald A. Grybeck, Raymond Wehr
1970, Open-File Report 70-71
Analytical data for 138 rock and 71 stream-sediment samples from the Sumdum A-3, 1:63,360 scale quadrangle are presented in this report, together with a statistical treatment of the data. The samples were collected in 1969 as part of the Heavy Metals Program of the U.S. Geological Survey.The most comprehensive discussion...
Analyses of rock and stream-sediment samples from the Craig C-6 Quadrangle, Alaska
Allen L. Clark, Henry C. Berg, Donald A. Grybeck, A. Thomas Ovenshine, Raymond Wehr
1970, Open-File Report 70-70
Analytical data for 26 rock and 8 stream-sediment samples from the Craig C-6, 1:63,360-scale quadrangle are presented in this report, together with a statistical treatment of the data. The samples were collected in 1969 as part of the Heavy Metals Program of the U.S. Geological Survey.The most comprehensive discussion of...
Lead-, zinc-, and barite-bearing samples from the western Brooks Range, Alaska, with a section on petrography and mineralogy
Irvin L. Tailleur, Ray Wehr, G. Donald Eberlein
1970, Open-File Report 70-319
Concentrations of base metal and barite of potential economic significance may be present in the western De Long Mountains, northwestern Alaska. Greater than 2 percent lead and 1 percent zinc were detected semiquantitatively in sulfide-bearing hand samples from one locality, and more than 10 percent lead was analyzed in a...
Flood frequency in Alaska
J.M. Childers
1970, Open-File Report 70-63
Records of peak discharge at 183 sites were used to study flood frequency in Alaska. The vast size of Alaska, its great ranges of physiography, and the lack of data for much of the State precluded a comprehensive analysis of all flood determinants. Peak stream discharges, where gaging-station records were...
A proposed streamflow-data program in Alaska
J.M. Childers
1970, Open-File Report 70-62
The streamflow-data program in Alaska was analyzed to design a better data network. The analysis included (1) definition of the goals of the streamflow-data program, (2) evaluation of the available data to see which goals have already been achieved, and (3) consideration and recommendation of future programs to achieve the...
Petroleum possibilities of the Yukon-Koyukuk Province, Alaska
William Wallace Patton Jr.
1970, Open-File Report 70-257
The recent discovery of major oil resources on Alaska's North Slope has rekindled interest in the petroleum possibilities of the Yukon-Koyukuk province, a vast tract of Cretaceous rocks stretching along the west coast of Alaska from the Brooks Range to the Yukon delta. Attention was first focused on this region...
Morphology, sedimentation, and seismic characteristics of an arctic beach, Nome, Alaska - with economic significances
H. Gary Greene
1970, Open-File Report 70-142
Arctic beaches exhibit characteristics that do not occur on beaches in more temperate zones. In the summer of 1967 morphological, sedimentological, and seismic refraction studies were made on an arctic beach near Nome, Alaska, in order to better define these distinguishing characteristics.Several distinct microrelief structures are developed during ice break-up...
Analysis of Shublik Formation rocks from Mt. Michelson quadrangle, Alaska
Robert L. Detterman
1970, Open-File Report 70-101
Analysis of 88 samples from the Shublik formation on Fire Creek, Mt. Michelson Quadrangle, Alaska, are presented in tabular form. The results include the determination of elements by semiquantitative spectrographic analysis, phosphate by X-ray fluorescence, carbon dioxide by acid decomposable carbonate, total carbon by induction furnace, carbonate carbon by conversion...
