Observations on the wet ashing of oils and asphaltenes
Herbert Mordecai Ezekiel
1955, Trace Elements Memorandum 864
The wet ashing of oils and aspbaltenes by sulfUric acid, percbloric acid, and nitric-sulfuric acid techniques is discussed and compared. A simple sulfuric acid=nitric acid technique which has been found to be satisfactory for these substances is described....

Uranium deposits of the northern part of the Boulder Batholith, Montana
George E. Becraft
1955, Trace Elements Memorandum 944
Uranium minerals and radioactivity anomalies occur in many silver-lead veins and chalcedony veins and vein zones in the Boulder batholith of southwestern Montanao Pitchblende has been identified in a few silver-lead veins. These veins occupy shear zones along which there is no evidence of large-scale lateral displacement. The wall rock...

Some physical properties of naturally irradiated fluorite
Robert Berman
1955, Trace Elements Investigations 569
Five samples of purple fluorite found in association with radioactive, materials, and a synthetic colorless control sample were studied and compared. Before and after heating, observations were made on specific gravity, index of refraction, unit-cell size, breadth of X-ray diffraction lines, and fluorescence. The purple samples became colorless on heating...
The thoron-tartaric acid systems for the spectrophotometric determination of thorium
F. S. Grimaldi, Mary H. Fletcher
1955, Trace Elements Investigations 571
Thoron is popularly used for the spectrophotometric determination of thorium. An undesirable feature of its use is the high sensitivity of the reagent toward zirconium. This study describes the use of tartaric acid as a masking reagent for zirconium. Three tartaric acid-thoron systems, developed for the determination of thorium, differ...
Water levels in observation wells in Santa Barbara County, California; in 1954
K. S. Muir
1955, Open-File Report 55-117
The investigation of the ground-water resources of Santa Barbara County was continued (luring 1954 in cooperation with the Santa Barbara County Wallet Agency. Monthly water-level measurements were made in 182 wells in 6 of which automatic water-level recorders were operated. Earlier measurements covering the period 1941 through 1952 have been...

A reconnaissance for uranium in carbonaceous rocks in southwestern Colorado and parts of New Mexico
Elmer H. Baltz Jr.
1955, Trace Elements Memorandum 915
Coal and carbonaceous shale of the Dakota formation of Cretaceous age were examined for radioactivity in the Colorado Plateau of southwestern Colorado and northwestern New l1exico during the summer of 1953. Older and younger sedimentary rocks and some igneous rocks also were examined, but in less detail, Weak radioactivity was...
Reconnaissance examination of the uranium deposits northeast of Winston, Broadwater County, Montana
George E. Becraft
1955, Trace Elements Memorandum 917
Anomalous radioactivity and a yellow secondary uranium mineral tentatively identified as carnotite have been found in Tertiary sedimentary rocks about 3 miles northeast of Winston, Mont. The uranium is in tuffs and tuffaceous shales and particularly in beds rich in organic matter. Carnotite(?) was identified from three localities, principally coating...
Some thorium prospects, Lemhi Pass area, Beaverhead County, Montana
Frank C. Armstrong
1955, Trace Elements Memorandum 918
The Last Chance group> Brown Bear and Shady Tree claims in Beaverhead County, Mont., were explored for thorium under a Defense Minerals Exploration Administration Contract in 1951 and 1952. The project was undertaken to explore northwest-trending moderately to steep dipping, thorite-bearing quartz-barite-hematite veins. The veins are wall-rock replacements and fissure fillings...
Preliminary experiments on the reduction of the uranyl ion to uraninite by carbonaceous substances
Irving A. Breger, Richard T. Moore
1955, Trace Elements Memorandum 942
An aqueous solution of uranyl sulfate containing a suspension of subbituminous coal has been heated at 210 C for three days. Examination of the coal at the end of the experiment showed it to contain 31.8 percent uranium recognizable as uraninite by a sharp, strong X-ray diffraction pattern. A similar...
