Composition of the earth's upper mantle-I. Siderophile trace elements in ultramafic nodules
J. W. Morgan, G.A. Wandless, R.K. Petrie, A.J. Irving
1981, Tectonophysics (75) 47-67
Seven siderophile elements (Au, Ge, Ir, Ni, Pd, Os, Re) were determined by radiochemical neutron activation analysis in 19 ultramafic rocks, which are spinel lherzollites-xenoliths from North and Central America, Hawaii and Australia, and garnet Iherzolitexenoliths from Lesotho.Abundances of the platinum metals are very uniform in spinel lherzolites averaging 3.4...
Plumbotectonics-the model
R. E. Zartman, B. R. Doe
1981, Tectonophysics (75) 135-162
Plumbotectonics is an attempt to model the geochemical behaviour of U, Th and Pb, among major terrestrial reservoirs in agreement with observational data. By recycling rock through the orogenic environment, a dynamically communicating upper crust, lower crust, and mantle can produce the required patterns of lead-isotope evolution. ...
A process-sedimentary framework for characterizing recent and ancient sabkhas
C.R. Handford
1981, Sedimentary Geology (30) 255-265
The discovery of sabkha environments during the 1960's, marked the beginning of Recent evaporite sedimentological studies and their perception as models for facies analysis. However, variation among Recent sabkhas, though recognized by the geologic community, has not been duly addressed, which has resulted in overuse of the Trucial Coast model...
Late Cenozoic marine deposition in the United States Atlantic Coastal Plain related to tectonism and global climate
B. W. Blackwelder
1981, Palaeogeography, Palaeoclimatology, Palaeoecology (34) 87-114
Major hiatuses in upper Cenozoic marine deposits in the United States Atlantic Coastal Plain are recognized on the basis of molluscan faunal changes at erosional unconformities. These hiatuses generally coincided with periods of global cooling and ice sheet formation. Such hiatuses provide information to supplement global climatic data. Major hiatuses...
Lower Eocene alluvial paleosols (Willwood Formation, Northwest Wyoming, U.S.A.) and their significance for paleoecology, paleoclimatology, and basin analysis
T. M. Bown, M. J. Kraus
1981, Palaeogeography, Palaeoclimatology, Palaeoecology (34) 1-30
The lower Eocene Willwood Formation of northwest Wyoming is a 700 m thick accumulation of alluvial floodplain and channel mudstones and sandstones, nearly all of which show paleopedogenic modifications. Pedogenesis of Willwood sandstones is indicated by taproot and vertebrate and invertebrate bioturbation, early local cementation by calcium carbonate, and thin...
Vertebrate fossil-bearing paleosol units (Willwood Formation, Lower Eocene, Northwest Wyoming, U.S.A.): Implications for taphonomy, biostratigraphy, and assemblage analysis
T. M. Bown, M. J. Kraus
1981, Palaeogeography, Palaeoclimatology, Palaeoecology (34) 31-56
In the lower 300 m of the fluvial Willwood Formation of northwest Wyoming, most large concentrations of vertebrate fossils consist of disarticulated and broken skeletal remains that occur in widespread, tubular, thin (2 cm-1 m) greenish- and bluish-gray mudstones that are low in percentage of free iron, aluminum, and manganese,...

E.K. Peterson, M.A. Letellier, J.A. Parsons, E.D. Plotka, L.D. Mech, U.S. Seal
1981, Physiology & Behavior (27) 543-546
A procedure for the surgical induction of anosmia in the wolf is described. Six wolves (4 altered and 2 sham) and one mongrel dog were operated; four wolves and the dog were bilaterally pedunculotomized, and two wolves were sham operated. Behavioral tests with the wolves confirmed that they were anosmic,...

Tonalites in crustal evolution
F. Barker, Joseph G. Arth, T. Hudson
1981, Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (301) 293-303
Tonalites, including trondhjemite as a variety, played three roles through geological time in the generation of Earth’s crust. Before about 2.9 Ga ago they were produced largely by simple partial melting of metabasalt to give the dominant part of Archaean grey gneiss terranes. These terranes are notably bimodal; andesitic rocks...
Floods in the English River basin, Iowa
A.J. Heinitz, D.E. Riddle
1981, Open-File Report 81-67
Information describing floods is essential for proper planning, design, and operation of bridges and other structures on or over streams and their flood plains. This report provides information on flood stages and discharges, flood magnitude and frequency, bench mark data, and flood profiles for the English River and some of its...
Gravity anomaly and interpretation map of the Chignik and Sutwik Island quadrangles, Alaska
J. E. Case, D.F. Barnes, R. L. Detterman, R. L. Morin, R. F. Sikora
1981, Miscellaneous Field Studies Map 1053-J
The gravity field of the Chignik and Sutwik Island quadrangles near the center of the Alaska Peninsula represents a complex series of transitions between probable continental crust on the north, probable oceanic crust on the south, sedimentary basins on each side of the peninsula, and a central structural high and volcanic arc. The resulting gravity field...
Waterfowl and their wintering grounds in Mexico, 1937-64
George B. Saunders, Dorothy Chapman Saunders
1981, Resource Publication 138
The U.S. Fish and Wildlife Service has been interested in migratory birds, especially waterfowl, in Mexico for many years, An early period of cooperation in waterfowl administration was culminated in 1937 with the final ratification of the Convention Between the United States and the United Mexican States for the Protection...
Procedures for the use of aircraft in wildlife biotelemetry studies

1981, Resource Publication 140
This is a report on the state of the art methodology and on questions that arise while one is preparing to use aircraft in a biotelemetry study. In general the first step in preparing to mount an antenna on an aircraft is to consult with a certified aircraft mechanic. Aircraft...
Seismic-reflection and sidescan-sonar data collected off eastern Cape Cod, Massachusetts, during April 1979
Harley J. Knebel
1981, Open-File Report 81-184
The U.S. Geological Survey collected 98 line kilometers of single-channel seismic-reflection profiles and sidescan sonar records on the inner shelf of eastern Cape Cod, Massachusetts, during April 1979. The data were obtained during cruise NE-1-79 of the R/V NEECHO. The purposes of the survey were: (1) to study the development...

Geochemistry of water in the Fort Union formation of the northern Powder River basin, southeastern Montana
Roger W. Lee
1981, Water Supply Paper 2076
Shallow water in the coal-bearing Paleocene Fort Union Formation of southeastern Montana was investigated to provide a better understanding of its geochemistry. Springs, wells less than 200 feet deep, and wells greater than 200 feet deep were observed to have different water qualities. Overall, the ground water exists as two...
