Two-garnet rodingite from Amador County, California
W. A. Duffield, M.H. Beeson
1973, Journal of Research of the U.S. Geological Survey (1) 665-672
Two distinct phases of garnet have been discovered in rodingite from Amador County, Calif. The two garnets are hydrogrossular and (hydro?) grossular-andradite. Only one, generally hydrogrossular, has been reported in rodingitcs studied by other workers. The rodingite of this study formed from a mafic dike with abundant euhedral plagioclase laths....

1973, Special Scientific Report - Wildlife 170
Birds imported into the United States in 1971 are tabulated by species. Total numbers for the period 1968-1971 are given for the more commonly imported taxa. The number of birds imported in 1971 increased only slightly over that for.1970. In 1971, 750 species were imported, of which...

Pesticide residues in birds and mammals

1973, Book chapter, Environmental Pollution by Pesticides
SUMMARY: Residues of organochlorine pesticides and their breakdown products are present in the tissues of essentially all wild birds throughout the world. These chemicals accumulate in fat from a relatively small environmental exposure. DDE and dieldrin are most prevalent. Others, such as heptachlor epoxide, chlordane, endrin, and benzene hexachloride...
Ground control requirements for precision processing of ERTS images
Thomas C. Burger
1973, Book
With the successful flight of the ERTS-1 satellite, orbital height images are available for precision processing into products such as 1:1,000,000-scale photomaps and enlargements up to 1:250,000 scale. In order to maintain positional error below 100 meters, control points for the precision processing must be carefully selected, clearly definitive on...
Sea level history in Beringia during the past 250,000 years
D.M. Hopkins
1973, Quaternary Research (3) 520-540
This paper attempts to relate current knowledge of sea-level history in Beringia to the Broecker-van Donk “Termination” concept of climatic and sea-level history. The Einahnuhtan transgression is thought to represent Termination III, which according to Broecker and van Donk, took place about 225,000...
Pleistocene succession of the central interior United States
J.C. Frye
1973, Quaternary Research (3) 275-283
The Quaternary of the continental interior of the United States is characterized by deposits from glacial ice, with associated outwash and eolian deposits, and by alluvial deposits produced by the same climatic pulses. Erosional incision of valleys occurred early in the glacial pulse, outwash deposition during the waning phase of...
Mechanisms of high-temperature, solid-state flow in minerals and ceramics and their bearing on the creep behavior of the mantle
Stephen H. Kirby, C.B. Raleigh
1973, Tectonophysics (19) 165-194
The problem of applying laboratory silicate-flow data to the mantle, where conditions can be vastly different, is approached through a critical review of high-temperature flow mechanisms in ceramics and their relation to empirical flow laws. The intimate association of solid-state diffusion and high-temperature creep in pure metals is found to...
Structure of the crust in the conterminous United States
David H. Warren, J. H. Healy
1973, Tectonophysics (20) 203-213
On the basis of the newest interpretations of all sufficiently long seismic profiles, a contour map of the Mohorovičić discontinuity for the conterminous United States is compiled. Differences from earlier interpretations are discussed....
Spectrophotometric procedure using rhodamine B for determination of submicrogram quantities of antimony in rocks
Marian M. Schnepfe
1973, Talanta (20) 175-184
A spectrophotometric procedure using Rhodamine B is given for the determination of antimony in mineralized rocks after its separation as stibine. A study of the Rhodamine B reaction points to the importance of the order of addition of reagents in enhancing sensitivity and increasing the stability...
