Zirconium and hafnium in the southeastern Atlantic States
J.B. Mertie Jr.
1958, Bulletin 1082-A
The principal source of zirconium and hafnium is zircon, though a minor source is baddeleyite, mined only in Brazil. Zircon is an accessory mineral in igneous, metamorphic, and sedimentary rocks, but rarely occurs in hardrock in minable quantities. The principal sources of zircon are therefore alluvial deposits, which are mined...
The geology of the Bishop 15-minute quadrangle, California
Paul Charles Bateman
1958, Open-File Report 58-11
The purpose of the study of the Bishop 15-minute quadrangle in east-central California was to appraise the mineral resources and to delineate and interpret the stratigraphic and structural history of the area. A report on the mineral resources has been published and the emphasis here is on stratigraphy and structure....
Geology of the Little Commonwealth area, Florence County, Wisconsin
Robert William Johnson Jr.
1958, Open-File Report 58-53
The Little Commonwealth exploration in northeastern Florence County, Wisconsin, is underlain by highly ferruginous clastic rocks that are stratigraphically equivalent to vitreous quartzite. The relationship between these rocks is one of abrupt facies change, with complete gradation between facies. This stratigraphic unit is conformably underlain by sericitic phyllite and unconformably...
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...
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...
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...
