Dispersion of copper from the San Manuel copper deposit, Pinal County, Arizona
T. S. Lovering, Lyman C. Huff, H. Almond
1950, Economic Geology (45) 493-514
At San Manuel, near Tucson, Arizona, recent churn drilling has blocked out large reserves of low-grade "porphyry copper" ore. This virgin deposit has a small outcrop and seems ideally suited for a geochemical study of the dispersion pattern produced by weathering in a desert climate. Samples of soils, alluvium, ground...
The appraisal of ore reserves at a Japanese copper mine
John J. Collins
1950, Economic Geology (45) 568-573
Estimates of ore reserves at major Japanese metal mines seem, at first glance, to be readily understandable to American engineers and geologists. Close scrutiny, however, generally reveals unexpected features at each mine. For example, the Hitachi copper mine formerly segregated its developed ore reserve into positive and probable on the...

Populations and home range relationships of the box turtle, Terrapene c. carolina (Linnaeus)
Lucille F. Stickel
1950, Ecological Monographs (20) 351-378
SUMMARY: A population study of the box turtle (Terrapene c. carolina Linnaeus) was made during the years 1944 to 1947 at the Patuxent Research Refuge, Maryland. A thirty acre area in well drained bottomland forest on the flood plain of the Patuxent River was...
"Lockhartia" cushmani Applin and Jordan and notes on two previously described foraminifera from tertiary rocks in Florida
Esther R. Applin, Louise Jordan
1950, Journal of Paleontology (24) 474-478
This paper discusses changes made in the names of three foraminiferal species originally described by the writers, with particular emphasis on "Lockhartia" cushmani Applin and Jordan. The internal characters of this form are fully described and compared with the diagnostic characteristics of the genus Lockhartia Davies and with the geno-lectotype...

A preliminary report on the rapid fluorimetric determination of uranium in low-grade ores
F. S. Grimaldi, Harry Levine
1950, Trace Elements Investigations 47
A simple and very rapid fluorimetric procedure is described for the determination of uranium in low-grade shale and phosphate ores. The best working range is from 0.001 to about 0.04 percent U. The procedure employs batch extraction of uranium nitrate by ethyl acetate, using aluminum nitrate as the salting agent,...

Stratigraphy and structure of the area of the upper Meade River, Alaska
Charles L. Whittington, Samuel A. Keller
1950, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 36
The stratigraphic evidence in the upper Meade River area includes zones B to D of the Nanushuk group (Cretaceous). Zones B and C are not differentiated in mapping and description. South of the Meade River 2,100 feet of zones B-C and 1,500 feet of zone D are exposed. North of...

Navy Oil Unit Party 4, during the summer field season of 1949, examined the surface geology of the area of the Okpikruak and Kiruktagiak Rivers. The party consisted of six men: two geologists, two field assistants, a weasel mechanic, and a cook. Three weasels were used for transportation in the...

An improved fluorimeter for the determination of uranium in fluoride melts
Mary H. Fletcher, Irving May
1950, Trace Elements Investigations 120
The Model R fluorimeter has been modified to increase its stability and sensitivity. The new instrument* is about ten times as sensitive as the original fluorimeter, but it can also be employed conveniently at a sensitivity level comparable to or less than that of the Model R fluorimeter. *The modified fluorimeter...

1950, Trace Elements Investigations 112
Between November 1947 and September 1949, the United States Geological Survey, at the request of the Atomic Energy Commission, conducted an exploratory drilling program in the Charles T. area and vicinity. The purpose of the exploration was to discover new carnotite deposits to support milling operations on the Colorado Plateau,...
A preliminary report on methods of determining the age of Colorado plateau carnotite
Lorin Rollins Stieff, M.N. Girhard, T. W. Stern
1950, Trace Elements Investigations 108
Four methods of dating Colorado Plateau carnotite have been examined and evaluated: mineralogic methods, radioactive-equilibrium methods, lead-uranium-ratio methods, and lead-isotope methods. The data on 12 high-grade samples, from a suite of 50 representative carnotite ores, are presented....
