The displacement of calibration curves for electrical soil‐moisture units
Irwin Remson, G. S. Fox
1955, Eos, Transactions, American Geophysical Union (36) 821-826
Electrical‐resistance blocks were calibrated for use in soil‐moisture studies at Seabrook, N.J. Curves from successive laboratory calibrations are positioned differently because of the effects of chemical quality of the water used, drying techniques and other factors. Furthermore, the laboratory curves are displaced from the field calibration curves because of the...
Capillary losses from ground water
Irwin Remson, G. S. Fox
1955, Eos, Transactions, American Geophysical Union (36) 304-310
A method is presented for estimating the discharge of ground water by evapotranspiration of water rising from the water table by capillarity. ‘Potential capillary water loss’ is defined as a measure of the ability of the capillary interstices of a soil to raise water from the water table to the...
Effect of current drought upon water supplies in Cedar City Valley, Utah
H.A. Waite, H.E. Thomas
1955, Eos, Transactions, American Geophysical Union (36) 805-812
The ground water in the pumping district in Cedar City Valley, Utah is considered by the Utah State Engineer to be fully appropriated, and he has not authorized drilling of irrigation wells there since 1942 except as replacements for wells having established rights. In spite of this regulation, the water...
Geochemistry and mineralogy of a uraniferous lignite [South Dakota]
Irving A. Breger, Maurice Deul, Samuel Rubinstein
1955, Economic Geology (50) 206-226
Detailed studies have been carried out on a uraniferous lignite from the Mendenhall strip mine, Harding County, S. Dak. By means of heavy-liquid separations, a mineral-free concentrate of the lignite was obtained that contained 13.8 percent ash and 0.31 percent uranium in the ash. The minerals (gypsum 69 percent, jarosite...
Comments on minor elements in pyrrhotite [Idaho]
V.C. Fryklund, R. S. Harner
1955, Economic Geology (50) 339-344
The cobalt and nickel content of pyrrhotite from the Highland-Surprise mine, Coeur d'Alene district, Idaho, was determined by spectrographic methods. The Co and Ni values fall within the ranges of values found by other investigators. Comparison of the distribution of Co and Ni in the Highland-Surprise ore shoot with the...
Is Carbon dioxide an ore-forming fluid under shallow-earth conditions?
R.M. Garrels, D.H. Richter
1955, Economic Geology (50) 447-458
A review of some of the physical-chemical properties of CO 2 and of the system CO 2 --H 2 O indicates that under some shallow-earth conditions CO 2 can exist as a separate phase with a density approximately that of water. The effect of dissolved neutral or acid salts on the solubility of CO 2 in H 2 O is not large....
Ground-water data collected in the Missouri River basin units in Kansas during 1954
B.J. Mason, Linda Loye
1955, Open-File Report 55-109
Ground-water studies in the Missouri River Basin were begun by the United States Geological Survey during the fall of 1945 as a part of the program for development of the resources of the basin by the U.S. Bureau of Reclamation and other Federal Agencies. The studies of the ground-water resources...
Salt-water encroachment as induced by sea-level excavation on Angaur Island
C.K. Wentworth, A.C. Mason, D.A. Davis
1955, Economic Geology (50) 669-680
Angaur, southwesternmost of the Palau Islands, 800 miles southwest of Guam, has an area of 3.2 square miles and consists of reef limestone of Pliocene through Recent age. In the northwestern part of the island a basin is formed by a ringlike ridge that has a maximum altitude of 150...
Geochemistry and mineralogy of a uraniferous sub bituminous coal
Irving A. Breger, M. Deul, R. Meyrowitz
1955, Economic Geology (50) 610-624
A sample of subbituminous uraniferous coal from the Red Desert, Sweetwater County, Wyo., has been studied mineralogically. The coal contains gypsum (6 percent), kaolinite (1 percent), quartz (0.3 percent), calcite (trace), and limonite (trace). This suite of minerals and the absence of pyrite show that the coal has been subjected...
Sequence of alluviation along the Loup rivers, Valley County area, Nebraska
Robert D. Miller, Glenn R. Scott
1955, GSA Bulletin (66) 1431-1448
Alluviation along the North and Middle Loup rivers in Valley County, Nebraska, produced a series of alluvial silt beds on which are developed five interstadial soils of Brady (?), Cary and Mankato (?), Mankato (?), early Recent and late Recent age. No deposits of Illinoian age were found and in...
The lead-zinc veins of the chilete mining district in northern Peru
F.S. Simmons
1955, Economic Geology (50) 399-419
Lead-zinc-silver veins in the Chilete mining district in the Department of Cajamarca in northern Peru have been worked sporadically since the 17th century, but the greatest activity dates only from 1951. The ore deposits are in a thick section of andesitic volcanic rocks that overlie with marked unconformity a sequence...
