The problem of groundwater discharge into the seas
B.I. Kudelin, I.S. Zekster, A.V. Meskheteli, S.A. Brusilovsky, F.W. Trainer
1971, Eos, Transactions, American Geophysical Union (52) 717-722
Introductory Note: The dynamic equilibrium of the various factors involved in the world water balance or budget is the central scientific problem of the International Hydrological Decade. One of the potentially vital elements of the balance is groundwater discharge to the oceans. To paraphrase the authors of the following Russian...

Age and chemistry of tertiary volcanic rocks in north-central Arizona and relation of the rocks to the Colorado Plateaus
Edwin H. McKee, Charles A. Anderson
1971, Geological Society of America Bulletin (82) 2767-2782
During late Miocene (14.8 m.y.) to early Pliocene (10.1 m.y.) time, local latite and widespread basaltic flows accumulated with associated continental sedimentary deposits in north-central Arizona. Some of these rocks were displaced and tilted by normal faults, and new drainage, now occupied in part by basalt flows of late Pliocene...
Metamorphism of Precambrian granitic xenoliths in a mica peridotite at Rose Dome, Woodson County, Kansas: Part 2, petrologic and mineralogic studies
Paul C. Franks, M. E. Bickford, Holly C. Wagner
1971, Bulletin of the Geological Society of America (82) 2869-2889
Field, drill-core, petrographic, and mineralogic studies show that the Precambrian granitic rocks exposed on Rose Dome, Woodson County, Kansas, were emplaced as inclusions of basement rock in a mica peridotite magma that intruded the Pennsylvanian section of Rose Dome during Late Cretaceous time. High temperatures of the alkaline ultramafic magma...
A method for discriminating between biogenic and chemical origins of the ore-stage pyrite in a roll-type uranium deposit
C. G. Warren
1971, Economic Geology (66) 919-928
Some roll-type uranium deposits are marginal to an altered tongue in sandstone beds that originally contained more-or-less uniformly distributed pyrite. Mineralizing solutions percolated through the sandstone, oxidized nearly all the pre-existing pyrite, and then redeposited part of the pyrite downstream in an embryonic ore zone....
Mesozoic granitic rocks in northwestern Nevada: A link between the Sierra Nevada and Idaho batholiths
James G. Smith, Edwin H. McKee, Donald Bruce Tatlock, Richard F. Marvin
1971, Bulletin of the Geological Society of America (82) 2933-2944
Extensive areas in northwestern Nevada are underlain by granodiorite and quartz monzonite plutons, as well as less common smaller bodies of quartz diorite. Twenty-six K/Ar age determinations on rocks from this suite range from about 175 to 85 m.y., but most of the plutons are...
The effect of salinity on the maximum thermal gradient of a hydrothermal system at hydrostatic pressure
John L. Haas Jr.
1971, Economic Geology (66) 940-946
The effect of salinity on the temperature-depth relations of a brine of constant composition, enclosed in a vein system, but freely connected to the surface, and everywhere at the boiling point for the hydrostatic head, was calculated by using a mathematical model. The Na-Ca-K-Cl brines...
Geochemical interpretations of groundwater flow systems
William Back, Bruce B. Hanshaw
1971, Journal of the American Water Resources Association (7) 1008-1016
Interest in the geochemistry of groundwater is increasing owing to the great number of current projects involving underground liquid waste storage, artificial recharge of potable water, accidental contamination of groundwater bodies, sanitary landfills, and pollution monitoring. Geochemical techniques used to facilitate the understanding of a groundwater...
Investigation of magnetization and density of a north Atlantic seamount using Poisson's theorem
Lindrith Cordell, Patrick Taylor
1971, Geophysics (36) 919-937
The relationship between the gravitational and magnetic potentials caused by a uniform distribution of mass and magnetization may be used to obtain independent information about these physical properties. The general relationship in the frequency domain between the Fourier transforms of the gravity and magnetic anomaly...
A device for monitoring radio-marked animals
D.S. Gilmer, V.B. Kuechle, I.J. Ball Jr.
1971, Journal of Wildlife Management (35) 829-832
A simple, portable, and economical recording system consisting of a receiver, signal conditioner, recorder, and power source is described. The system was designed to monitor the signal strength from a radio-marked animal at a particular location. Information is stored on recorder chart paper. Radio-marked ducks have been successfully monitored at...
Effects of introducing foxes and raccoons on herring gull colonies
J.A. Kadlec
1971, Journal of Wildlife Management (35) 625-636
Red foxes (Vulpes fulva) and raccoons (Procyon lotor) released at colonies of herring gulls (Larus argentatus) on islands off the Massachusetts coast effectively eliminated the production of young gulls. Annual predator introductions for 2-4 years caused major reductions in colony size and occasionally total abandonment of the island as a...

Channel catfish virus: A new herpesvirus of ictalurid fish
K. Wolf, R. W. Darlington
1971, Journal of Virology (8) 525-533
Channel catfish virus was studied in ictalurid fish cell culture, the only system of fish, amphibian, avian, and mammalian cells found to be susceptible. Channel catfish virus infection resulted in intranuclear inclusions and extensive syncytium formation. Replication occurred from 10 to 33 C, but not higher. Best growth was from...

Waterfowl nesting on interstate highway right-of-way in North Dakota
R.B. Oetting, J.F. Cassel
1971, Journal of Wildlife Management (35) 774-781
We studied 630 acres of roadside along 23 miles of Interstate 94 in Stutsman County, North Dakota, to assess wildlife values of highway rights-of-way. We found 422 duck nests that had an overall success of 57 percent in 1968, 1969, and 1970. Mammalian predators were responsible for 85 percent of...
A starling-deterrent wood duck nest box
Frank B. McGilvrey, Francis M. Uhler
1971, Journal of Wildlife Management (35) 793-797
In many parts of the United States, the starling (Sturnus vulgaris) has I become a serious competitor for nest boxes erected for wood ducks (Aix sponsa). Research at the Patuxent Wildlife Research Center and at Eastern Neck National Wildlife Refuge near Rock Hall, Maryland, demonstrated that horizontal nest structures with...
Ground water in the Aden sector of Southern Arabia
D.J. Cedarstrom
1971, Ground Water (9) 29-34
A reconnaissance of parts of the former West Aden Protectorate enables a characterization of the dominant hydrologic elements to be made. In this desert environment intermittent streams from the east‐west range of mountains provide considerable water for flood irrigation and groundwater recharge of alluvial fans along the Gulf of Aden....
Geological aspects of the May 31, 1970, Perú earthquake
George Plafker, G. E. Ericksen, Jamie Fernandez Concha
1971, Bulletin of the Seismological Society of America (61) 543-578
Geological effects of the destructive May 31, 1970, Perú earthquake (Ms = 7.7) extended over roughly 65,000 km2 of west-central Perú. Earthquake-triggered slope failures of all types that occurred throughout the mountainous parts of the region extensively damaged transportation routes and irrigation canals and temporarily dammed some rivers and lakes....

Plate tectonics and magmatic evolution
James Gilluly
1971, Bulletin of the Geological Society of America (82) 2383-2396
The validity of the general idea of plate tectonics is accepted; the magmas evolved along the spreading ridges are thought to be largely tholeiitic basalt, although alkalic olivine basalt and...
