The killifish, fundulus heteroclitus, second intermediate host of the trematode, Ascocotyle (Phagicola) dimunuta
H. W. Stunkard, Joseph R. Uzmann
1955, Biological Bulletin (109) 475-483
Ascocotyle (Phagicola) diminuta was described by Stunkard and Haviland (1924)from the intestine of wild rats collected at the Clason Point dump near New York by the City Board of Health. Feeding experiments have demonstrated that metacercariae encysted in the gills of the common killifish, Fundulus hetero clitus, are stages in...
Memorandum describing the geology and ground-water conditions in the vicinity of Simpsonville, Maryland
E. G. Otton
1955, Open-File Report 55-127
This memorandum summarizes briefly the result of a study of the ground-water conditions of a small area near Simpsonville, Maryland, underlain chiefly by the Guilford granite (granite-pegmatite) of early Paleozoic or late Precambrian age. The records. of 15 wells and 5 sprints are given, as are t he sample-study legs...
Isotopic composition and distribution of lead, uranium, and thorium in a Precambrian granite
G.R. Tilton, C.C. Patterson, Harrison Brown, Mark Inghram, R.R. Hayden, David Hess, Esper S. Larsen Jr.
1955, GSA Bulletin (66) 1131-1148
The isotopic compositions and concentrations of lead and uranium have been determined in some separated minerals and the composite of a granite from Monmouth township, Haliburton County, Ontario. The chemical and mass spectrometric methods that were used are described. The age of the zircon from the granite is 1050 million...
Pleistocene geology of the southwestern Wind River Mountains, Wyoming
G.W. Holmes, J.H. Moss
1955, GSA Bulletin (66) 629-654
Patches of Buffalo till record the earliest glaciation in the southwestern Wind River Mountains. In places, these rest in youthful valleys cut in high gravel terrace. Two other younger and lower terraces are both topographically and stratigraphically associated with Buffalo till, which may indicate that the Buffalo advance was compound....

Discussion of symposium on land erosion “Piping”
L.A. Heindl, J. H. Feth, J.E. Fletcher, Karl Harris, H.B. Peterson, V.N. Chandler
1955, Eos, Transactions, American Geophysical Union (36) 342-345
The present writers are familiar only with the Picacho and San Pedro areas, among those cited by the authors, and therefore limit discussion to the occurrence of earth cracks in these areas.The existence of piping is not questioned, and the five conditions suggested by the authors are a justified explanation...
Origin of the upland silt near Fairbanks, Alaska
T. L. Pewe
1955, GSA Bulletin (66) 699-724
Silt mantles the upland slopes and ridge tops throughout the unglaciated interior of Alaska, reaching maximum thickness along the north side of the Tanana River Valley. The silt is probably loess deposited during glacial advances by south winds blowing from the glaciated Alaska Range across outwash plains in the Tanana...
A pumping‐test method for the determination of specific yield
Irwin Remson, S.M. Lang
1955, Eos, Transactions, American Geophysical Union (36) 321-325
The specific yield of a water‐table aquifer is one measure of the amount of water within the aquifer that is available for recovery (development). It is expressed as a percentage or decimal fraction of the total volume of material of which the aquifer is composed. The specific yield may be...
Catoctin formation near Luray, Virginia
J. C. Reed Jr.
1955, GSA Bulletin (66) 871-896
In the Blue Ridge Province of northern Virginia, Maryland, and southern Pennsylvania the established lower Cambrian beds are underlain by a thick sequence of greenstone and interbedded sedimentary rocks known as the Catoctin formation. In an effort to determine the thickness of the formation, its relationship to overlying and underlying...
Effect of western drought on the water resources of Safford Valley, Arizona, 1940–1952
R.L. Cushman, L. C. Halpenny
1955, Eos, Transactions, American Geophysical Union (36) 87-94
Records of precipitation, runoff in the Gila River, ground‐water withdrawals for irrigation, and changes in ground‐water level in Safford Valley, Arizona, provide a basis for noting the effect of wet and dry periods on the hydrologic cycle. An unusually wet period 1940–1941, was followed by a period of drought, l942–1952....
Geologic thermometry
E. Ingerson
1955, GSA Special Papers (62) 465-488
The methods of measuring and estimating temperatures of geologic processes are examined critically. Data for some of the more accurate methods of wide geologic application are summarized by means of tables and graphs. Attention is called especially to two methods that have been used increasingly the last several years: (1)...
Development of the hydrosphere and atmosphere, with special reference to probable composition of the early atmosphere
William W. Rubey
1955, GSA Special Papers (62) 631-650
A satisfactory hypothesis of the development of the hydrosphere and atmosphere depends upon evidence from many sciences and the solution of many other fundamental problems of earth history. But because it is so closely related to many other problems, any progress toward unravelling the history of the hydrosphere and atmosphere...
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....
