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...
Areal geology of the Little Cone quadrangle, Colorado
Alfred Lerner Bush, O.T. Marsh, Richard Bartlett Taylor
1958, Trace Elements Investigations 602
The Little Cone quadrangle includes an area of about 59 square miles in eastern San Miguel County in southwestern Colorado. It lies within and adjacent to the northeastern boundary of the Colorado Plateau physiographic province. The precipitous front of the San Juan Mountains lies a few miles to the east...
Physical properties of salt, anhydrite and gypsum : preliminary report
Eugene C. Robertson, Richard A. Robie, Kenneth G. Books
1958, Trace Elements Memorandum 1048
This summary is the result of a search of the available literature. Emphasis is placed on the mechanical and calorimetric properties of salt; the measurements of elastic, thermal, magnetic, and mass properties of salt are merely tabulated. Under hydrostatic pressure < 1,000 kg/cm2 at room temperature, salt deforms plastically to...
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...
Geology of part of the Fanny Peak quadrangle, Wyoming-South Dakota
Jack Burton Epstein
1958, Open-File Report 58-35
The Fanny Peak quadrangle is located on the west flank of the Black Hills. The exposed strata total over 4000 feet in thickness and range in age from Mississippian to late Cretaceous. Local surficial Cenozoic deposits are common.The upper 200 to 300 feet of the Minnelusa formation is a breccia...
