The isolation and identification of Trypanosoma cruzi from raccoons in Maryland
B. C. Walton, P. M. Bauman, L. S. Diamond, Carlton M. Herman
1958, American Journal of Tropical Medicine and Hygiene (7) 603-610
Five raccoons trapped at Patuxent Research Refuge, Laurel, Maryland, were found to have trypanosomes in the blood which were morphologically indistinguishable from Trypanosoma cruzi on stained smears. The organism grew well in culture. It developed and reproduced in Triatoma protracta, T. infestans, T. phyllosoma, and Rhodnius prolixus. Experimental infections were produced in raccoons, opossums,...
The solusphere - its inferences and study
F. H. Rainwater, W. F. White
1958, Geochimica et Cosmochimica Acta (14) 244-249
Water is a fundamental geologic agent active in rock decomposition, erosion, and synthesis. Solutes in water are of particular interest to geochemists as sources of raw material for synthesis or as products of decomposition. When geochemical studies move from the laboratory into natural environment many variables relating to solute hydrology...
Geology of Kapingamarangi Atoll, Caroline Islands
Edwin D. McKee
1958, GSA Bulletin (69) 241-278
Kapingamarangi Atoll of the Caroline Islands consists of a peripheral reef, 1000-4000 feet across, surrounding a nearly circular lagoon which is 5 by 6 nautical miles in area and about 240 feet at maximum depth. Thirty-three islands, most of which are less than half a mile in length, are scattered...
Geology of the north half of the Mt. Abbot quadrangle, Sierra Nevada, California
D. G. Sherlock, Warren Hamilton
1958, GSA Bulletin (69) 1245-1268
The north half of the 15-minute Mt. Abbot quadrangle lies across the crest of the Sierra Nevada. The Cretaceous granitic rocks that underlie most of the area form eight large discordant plutons that range from quartz diorite to alaskite; the largest pluton is coarse prophyritic quartz monzonite. Pre-batholithic metasedimentary and...
Recent underwater surveys using low-frequency sound to locate shallow bedrock
W. O. Smith
1958, GSA Bulletin (69) 69-98
Underwater investigations at Lake Mead, Chicago, Passamaquoddy Bay, and on Long Island established the characteristics of sound waves that can be used in shallow geophysical exploration by the sonar method.At Lake Mead the sediments were for the most part clay of high water content which was easily penetrated by low-power...
The relation of phosphorites to ground water in Beaufort County, North Carolina
P.M. Brown
1958, Economic Geology (53) 85-101
Recent ground-water studies undertaken by the U.S. Geological Survey in cooperation with the North Carolina Division of Mineral Resources have delineated phosphorite deposits, tentatively regarded as being of middle Miocene age, in Beaufort County. These deposits lie unconforma-bly on limestone of Eocene age and are unconformably overlain by late Miocene...
Minerals of the cassiterite-bearing veins at Irish Creek, Virginia, and their paragenetic relations
Jewell J. Glass, A. H. Koschmann, John Stewart Vhay
1958, Economic Geology (53) 65-84
Major rock types of the Irish Creek district are gneisses and schists, intruded by granodiorite. All these rocks are believed to be Precambrian. The ore deposits are fissure veins consisting largely of quartz veins bordered by greisen, and enriched by recurrent deposition. From field and microscopic evidence six stages of...
Uranium deposits under conglomeratic sandstone of the Morrison Formation, Colorado and Utah
D. A. Phoenix
1958, GSA Bulletin (69) 403-418
In southwestern Colorado and southeastern Utah, strata of conglomeratic sandstone are localized at the base of the Brushy Basin Member of the Morrison Formation of Jurassic age. These discrete lithologic units contain sedimentary structures oriented in a prevailing easterly direction. They are believed to cover about one-third of the underlying...
Contact metamorphism adjacent to a teschenite intrusion
Howard G. Wilshire
1958, Journal of the Geological Society of Australia (6) 11-20
Shale adjacent to the upper contact of an annular teschenite intrusion was converted to andalusite hornfels in an aureole 2–4 feet wide. At some points along the contact there is no evidence of anhydrous recrystallization. Rarely, magmatic reaction with small shale xenoliths resulted in formation of cordierite‐sillimanite (?) hornfelses, and...
Radiotracer experiments in the Mohawk River, New York, to study sewage path and dilution
Eugene S. Simpson, W. Arthur Beetem, F. H. Ruggles
1958, Eos, Transactions, American Geophysical Union (39) 427-433
Sewage from the Knolls Atomic Power Laboratory near Schenectady, N. Y., was dosed with 4.53 curies of P prior to discharge into the Mohawk River. Its pattern of diffusion was measured in the river with immersible GM‐tubes and by sampling. The initial path of sewage was strongly influenced by differences...
Application of statistical methods to the analysis of ground‐water levels
Irwin Remson, J.R. Randolph
1958, Eos, Transactions, American Geophysical Union (39) 75-83
Valuable hydrologic information can be obtained from statistical analysis of water‐level trends. The time‐series and the functional‐equation approaches are applied to New Jersey well records representing different hydrologic conditions. The results are valuable as concise summaries of the records, for extrapolating observed data, for interpolating between measurements, and for estimating...
Reconnaissance study of erosion and deposition produced by the flood of August 1955 in Connecticut
M. Gordon Wolman, J.P. Eiler
1958, Eos, Transactions, American Geophysical Union (39) 1-14
A large area in the valley bottoms in Connecticut was inundated by the flood of August 1955. Relative to the total area flooded that part permanently modified by the flow was surprisingly small. Although great in some places, the distribution of these permanent modifications of channel and flood plain was...
Lower ordovician section near Chambersburg, Pennsylvania
William Jasper Sando
1958, GSA Bulletin (69) 837-854
The Lower Ordovician series (Beekmantown group) is at least 3500 feet thick near Chambersburg, Pennsylvania, approximately 1200 feet thicker than was earlier estimated. Reverse faulting in the upper part of the section may have obscured the youngest Early Ordovician and oldest Middle Ordovician beds in the area, so that the...
