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 Inasmuch as many open-file reports are preliminary and eventually superseded by final published reports, it is inappropriate to include references to open-file reports in a permanent index.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...
Atlas of Mars chart, Thaumasia Quadrangle, MC-25
United States Geological Survey
1973, Open-File Report 73-340
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars chart, Argyre Quadrangle, MC-26
United States Geological Survey
1973, Open-File Report 73-341
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Stability of salt in the Permian salt basin of Kansas, Oklahoma, Texas, and New Mexico, with a section on dissolved salts in surface water
George Odell Bachman, Ross Byron Johnson
1973, Open-File Report 73-14
The Permian salt basin in the Western Interior of the United States is defined as that region comprising a series of sedimentary basins in which halite and associated salts accumulated during Permian time. The region includes the western parts of Kansas, Oklahoma, and Texas, and eastern parts of Colorado and...
Atlas of Mars chart, Aeolis Quadrangle, MC-23
United States Geological Survey
1973, Open-File Report 73-339
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
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...
Erosion processes, fluvial sediment transport, and reservoir sedimentation in a part of the Newell and Zayante Creek basins, Santa Cruz County, California
W. M. Brown III
1973, Open-File Report 73-35
The drainage basins upstream from Loch Lomond, a water-supply reservoir on Newell Creek, and a proposed reservoir site on Zayante Creek were investigated for their characteristics with respect to the erosion, transportation, and deposition of sediment. The study area is underlain predominantly by sandstone, siltstone, and shale of Tertiary age...
