F.W. O’Malley, D.F. Davidson, R.A. Hoppin, R.P. Sheldon
1951, Trace Elements Investigations 188
.The U.S. Geological Survey has measured and sampled the Phosphoria formation at many localities in Idaho and other western states. These data will not be fully synthesized and analyzed for several years but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they...
Airborne radioactivity survey in the vicinity of Grants, McKinley and Valencia Counties, New Mexico
Frank W. Stead
1951, Trace Elements Memorandum 161
An airborne radioactivity survey in the vicinity of Grants, New Mexico, was made on May 28. 1951; aeromagnetic measurements were made concurrently with the radioactivity measurements. Several radioactivity anomalies were noted in conjunction with negative magnetic anomalies; this association is unusual and may reflect a genetic relationship between the uranium...
Notes on the manganese ores of Brazil
C. F. Park Jr., J. V. N. Dorr, P. W. Guild, A. L. M. Barbosa
1951, Economic Geology (46) 1-22
Brazil has been a small but consistent source of manganese ore for world markets during the last five decades. Production both for export and for domestic use is likely to increase. Deposits can be classified into syngenetic (the primary manganese sediments in iron formation at Urucum) and epigenetic. The epigenetic...
Preliminary report on the geology and ground-water supply of the Newark, New Jersey, area
Henry Herpers, Henry C. Barksdale
1951, Special Report (New Jersey Division of Water Policy and Supply) 10
In the Newark area, ground water is used chiefly for industrial cooling, air-conditioning, general processing, and for sanitary purposes. A small amount is used in the manufacture of beverages. Total ground-water pumpage in Newark is estimated at not less than 20,000,000 gallons daily. The Newark area is underlain by formations of...

Conservation: Where we stand: Review of Water, land, and people
Luna Bergere Leopold
1951, The Living Wilderness (36)
A distinguished conservationist, just returned from more than a year in those Pacific islands held in trust by the United States, reports that representatives of the government there are nearly completely concerned with the maintenance of an administrative organization. Actual advances in matters of land use, of maintaining the material...

Downstream movement of recently transformed sea lampreys, Petromyzon marinus, in Carp Lake River, Michigan
Vernon C. Applegate, Clifford L. Brynildson
1951, Transactions of the American Fisheries Society (81) 275-290
In order to obtain more precise information concerning the downstream movement of recently transformed sea lampreys, a trapping device was operated in the Carp Lake River, Emmet County, Michigan, from October, 1948, to July, 1951. The period of downstream migration typically extends from the latter part of October to...

Determination of molybenum in soils and rocks: A geochemical semimicro field method
F. N. Ward
1951, Analytical Chemistry (23) 788-790
Reconnaissance work in geochemical prospecting requires a simple, rapid, and moderately accurate method for the determination of small amounts of molybdenum in soils and rocks. The useful range of the suggested procedure is from 1 to 32 p.p.m. of molybdenum, but the upper limit can be extended. Duplicate determinations on...
Determination of fluorine in organic compounds: Microcombustion method
H. S. Clark
1951, Analytical Chemistry (23) 659-661
A reliable and widely applicable means of determining fluorine in organic compounds has long been needed. Increased interest in this field of research in recent years has intensified the need. Fluorine in organic combinations may be determined by combustion at 900° C. in a quartz tube with a platinum catalyst,...
Geochemical field method for determination of nickel in plants
L.E. Reichen
1951, Analytical Chemistry (23) 727-729
The use of biogeochemical data in prospecting for nickel emphasizes the need for a simple, moderately accurate field method for the determination of nickel in plants. In order to follow leads provided by plants of unusual nickel content without loss of time, the plants should be analyzed and the results...
Fluorometric determination of zirconium in minerals
W.C. Alford, L. Shapiro, C. E. White
1951, Analytical Chemistry (23) 1149-1152
The increasing use of zirconium in alloys and in the ceramics industry has created renewed interest in methods for its determination. It is a common constituent of many minerals, but is usually present in very small amounts. Published methods tend to be tedious, time-consuming, and uncertain as to accuracy. A...

C. E. White, M. H. Fletcher, J. Parks
1951, Analytical Chemistry (23) 478-481
The gravimetric method in general use for the determination of lithium is tedious, and the final weighed product often contains other alkali metals. A fluorometric method was developed to shorten the time required for the analysis and to assure that the final determination is for lithium alone. This procedure is...
