Bedrock geology of the Thiel Mountains, Antarctica
A. B. Ford, J.M. Aaron
1962, Science (137) 751-752
Cordierite-bearing, hyper-sthene-quartz monzonite porphyry, the most widespread rock unit, is intruded by biotite granite and porphyritic biotite granite. Sedimentary and metasedimentary rocks, mainly quartzites and argillites, have been metamorphosed locally to hornfels and have been involved in high-angle faulting. Shear zones are common in the plutonic rocks....
Concentration method for the spectrochemical determination of seventeen minor elements in natural water
W. D. Silvey, R. Brennan
1962, Analytical Chemistry (34) 784-786
A method for the quantitative spectrochemical determination of microgram amounts of 17 minor elements in water is given. The chelating reagents 8-quinolinol, tannic acid, and thionalide are utilized to concentrate traces (1 to 500 μg.) of aluminum, cobalt, chromium, copper, iron, gallium, germanium, manganese, nickel, titanium, vanadium, bismuth, lead, molybdenum,...
Temperature dependence of decay time and intensity of alpha pulses in pure and thallium-activated cesium iodide
F. E. Senftle, P. Martinez, V. P. Alekna
1962, Review of Scientific Instruments (33) 819-822
The intensity and decay time of Po210 alpha particle scintillations produced in pure and thallium‐activated cesium iodide have been measured with a fast electronic system as a function of temperature down to 77°K. Three modes of decay due to alpha excitation have been observed for CsI(Tl), and two for CsI. Other than...
The detection of sulphur in contamination spots in electron probe X-ray microanalysis
I. Adler, E.J. Dwornik, H. J. Rose Jr.
1962, British Journal of Applied Physics (13) 245-246
Sulphur has been identified as one of the elements present in the contamination spot which forms under the electron beam in the microprobe. The presence of the sulphur results in a rapid change in intensity measurements causing a loss of observed intensity for elements other than sulphur. The source of...
Nordstrandite from Guam
J.C. Hathaway, S.O. Schlanger
1962, Nature (196) 265-266
NORDSTRANDITE (Al2O3·3H2O), previously reported only as a synthetic product1,2, occurs in Miocene limestone on Guam. In south Guam this limestone forms a cap several hundred feet thick, on the Mount Alifan–Mount Lamlan ridge, and overlies late Eocene and early Miocene basalt flows and volcanic conglomerates. The volcanic rocks below the...
Geology and ore deposits of the Globe-Miami district, Arizona
N. P. Peterson
1962, Professional Paper 342
The rocks of the Globe-Miami district range from lower Precambrian to Recent. The oldest formation, the Pinal schist, comprises several varieties of schist formed by dynamic and thermal metamorphism of shale and feldspathic sandstone during the early Precambrian Mazatzal revolution. During the later stages of this revolution, the schist was...
Water
Luna Bergere Leopold, Helene L. Baldwin
1962, Book
What do you use water for?If someone asked you this question you would probably think right away of water for drinking. Then you would think of water for bathing, brushing teeth, flushing the toilet. Your list would get longer as you thought of water for cooking, washing the dishes, running...
The occurrence of the longjaw cisco, Leucichthys alpenae, in Lake Erie
W. B. Scott, Stanford H. Smith
1962, Journal of the Fisheries Research Board of Canada (19) 1013-1023
The longjaw cisco, Leucichthys alpenae, is shown to be a species new to the Lake Erie fauna. The taxonomic work on Lake Erie ciscoes is reviewed. Thirty three specimens of L. alpenae taken in 1946, 1947 and 1957 are compared morphometrically with Leucichthys artedi of Lake Erie, the only other cisco species in the lake. L. alpenae has a...
Water and the arid zone of the United States
Luna Bergere Leopold
1962, Conference Paper
In a pluvial period associated with Wisconsin glaciation the closed basin of the Estancia Valley in New Mexico held a lake which, at its maximum extent, was 150 feet deep and had a surface area of 450 square miles. This basin, with a mean elevation of about 6,000 feet, has...
Relation of the deep and shallow artesian aquifers near Lynndyl, Utah
R. W. Mower
1961, Utah State Engineer Information Bulletin 7
Ground water occurs in several aquifers in the vicinity of Lynndyl, Utah. There are one shallow perched water-table aquifer and at least two artisan aquifers. The perched aquifer is not related to the artisan aquifers and, because it is relatively unimportant, is not discussed here. Pumping tests made during the...
Developing ground water in the central Sevier Valley, Utah
Richard A. Young, Carl H. Carpenter
1961, Utah State Engineer Information Bulletin 5
This report presents a summary of conclusions reached from the recently completed State Engineer-United States Geological Survey cooperative investigation of the geology and ground water resources of the central Sevier River Valley. The detailed report will be published as a United States Geological Survey water supply paper and will be...
Geology and ground-water resources of Sumner County, Kansas
K.L. Walters
1961, Kansas Geological Survey Bulletin (151)
This report describes the geography, geology, and ground-water resources of Sumner County in south-central Kansas. The hydrologic and geologic data upon which this report is based were obtained in the field during the summers of 1955 and 1956. Records of 300 wells and 2 springs, chemical analyses of 219 water...
Trout hepatoma--a preliminary report
R.R. Rucker, W. T. Yasutake, H. Wolf
1961, Progressive Fish-Culturist (23) 3-7
Fish pathology and its role in fish culture were brought into prominence in the spring of 1960 by the disclosure of a high incidence of hepatomas in hatchery-reared rainbow trout. The current problem came to light as the result of a routine inspection of live trout shipments at a California...
Blood types in Pacific salmon
G.L. Ridgway, G.W. Klontz
1961, International North Pacific Fisheries Commission Bulletin 49-55
Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (0. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were...
