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...
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...
Airborne radioactivity surveys in geologic exploration
R.M. Moxham
1958, Trace Elements Investigations 662
The value of airborne radioactivity surveys in guiding uranium exploration has been well established. Recent improvements in circuitry and development of semiquantitative analytical techniques permit a more comprehensive evaluation of the geologic distribution of radioactive materials that may prove useful in exploration for other minerals and in regional geologic studies....
Reconnaissance of beryl-bearing pegmatites in the Ruby Mountains, other areas in Nevada, and northwestern Mohave County, Arizona
Jerry Chipman Olson, E. Neal Hinrichs
1957, Trace Elements Investigations 655
Pegmatite occurs widely in Nevada and northwestern Arizona, but little mining has been done for such pegmatite minerals as mica, feldspar, beryl, and lepidolite.  Reconnaissance for beryl-bearing pegmatite in Nevada and in part of Mohave County, Ariz., and detailed studies in the Dawley Canyon area, Elko County, Nev., have shown...
Distribution of elements in the Salt Wash member of the Morrison Formation in the Jo Dandy area, Montrose County, Colorado
William L. Newman, Donald P. Elston
1957, Trace Elements Investigations 607
A study of the distribution of elements in the Salt Wash member of the Morrison formation of Jurassic age from samples taken in the Jo Dandy area, Montrose County, Colo., was made to determine average chemical composition of mudstone and sandstone and to determine the magnitude of variations in concentrations...
