Mineralogical applications of electron diffraction. 1. Theory and techniques
Malcolm Ross, C. L. Christ
1958, Trace Elements Investigations 597
The small wavelengths used in electron-diffraction experiments and the thinness of the crystals necessary for the transmission of the electron beam combine to require a somewhat different diffraction geometry for the interpretation of electron-diffraction patterns than is used in the interpretation of X-ray diffraction patterns. This geometry, based on the...
Periodic heat flow in a stratified medium with application to permafrost problems
Arthur H. Lachenbruch
1958, Open-File Report 58-57
Solutions to the Fourier heat equation for quasi-steady periodic flow in a stratified semi-infinite medium can be obtained readily by standard methods. The results have wide application to studies of earth-temperature variations induced by diurnal, annual, and other periodic variations in ground surface temperature. Much of the previous work on...
Photogeological map of the Flat Top Moutain NE quadrangle Carbon County, Wyoming
A. B. Olson
1958, Trace Elements Memorandum 985
Flat Top Mountain NE quadrangle is on the eastern rim ot the Washakie Basin. The Wasatch and Green River formations crop out in the map area and dip generally to the west. The even and persistent bedding of the Green River formation, combined with the strong benching of a few...
Preliminary report on the ground-water resources of the Klamath River basin, Oregon
Reuben Clair Newcomb, D. H. Hart
1958, Open-File Report 58-73
The Klamath River basin, including the adjacent Lost River basin, includes about 5,500 square miles of plateaus, mountain-slopes and valley plains in south-central Oregon. The valley plains range in altitude from about 4,100 feet in the south to more than 4,500 feet at the northern end; the mountain and plateau...
Directional resistivity measurements in exploration for uranium deposits on the Colorado Plateau
George V. Keller
1958, Trace Elements Investigations 594
A study of the electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateaus province indicated that there is a significant correlation between electrical resistivity and the relative favorability for occurrence of ore. The differences in resistivity were not large enough to provide a recognizable...
