Electrical properties of sandstones of the Morrison Formation
George Vernon Keller
1957, Trace Elements Investigations 592
The electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau have been studied to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting. Measurements of electrical properties of...
The Gas Hills uranium district and some probable controls for ore deposition
Howard Davis Zeller
1957, Trace Elements Memorandum 1074
Uranium deposits occur in the upper coarse-grained facies of the Wind River formation of Eocene age in the Gas Hills district of the southern part of the Wind River Basin. Some of the principal deposits lie below the water table in the unoxidized zone and consist of uraninite and coffinite...
River channel patterns: Braided, meandering, and straight
Luna Bergere Leopold, M. Gordon Wolman
1957, Professional Paper 282-B
Channel pattern is used to describe the plan view of a reach of river as seen from an airplane, and includes meandering, braiding, or relatively straight channels.Natural channels characteristically exhibit alternating pools or deep reaches and riffles or shallow reaches, regardless of the type of pattern.

Estimate of underflow in the Niobrara River Basin across the Wyoming-Nebraska state line
H. M. Babcock, Charles F. Keech
1957, Open-File Report 57-4
The purpose of this report is to estimate the amount of ground water flowing across the Wyoming-Nebraska State line within the Niobrara Rive basin and to evaluate the accuracy of that estimate. The approximate effort involed in obtaining additional data to determine the underflow more accurately also is discussed. This report...
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...
