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....

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...
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...
Waterfowl nesting on interstate highway right-of-way in North Dakota

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...
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...
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....
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...
Protective pumping to reduce aquifer pollution, Glynn County, Georgia
Dean O. Gregg
1971, Groundwater (9) 21-29
Water-level declines in the principal artesian aquifer have created a head imbalance between the aquifer and an underlying brackish-water zone containing up to 4,550 mg/1 chloride. The brackish-water zone leaks brackish water into the aquifer through several breaks in a confining unit.A relief well tapping the brackish-water zone was drilled...

H. E. LeGrand, V. T. Stringfield
1971, Economic Geology (66) 701-709
The hydrogeologic history of the Tertiary limestone system of the Southeastern States is reconstructed, especially as it relates to circulation of ground water and the development of solution cavities. The development of these solution cavities resembles in many respects the development of cavities in carbonates...
A geochemical hypothesis for dolomitization by ground water
B.B. Hanshaw, W. Back, R.G. Deike
1971, Economic Geology (66) 710-724
Most modern disordered dolomite has been found in dynamic environments. However, solutions associated with modern dolomite formation do not have a common Mg/Ca ratio; the ratio ranges from about 3 to 100. Ground-water circulation may have a significant role in formation of regional dolomites; one of the primary requirements for...
