1980, Physics and Chemistry of the Earth (12) 321-332
Concentrations of amino acids and their corresponding dl">dl enantiomeric ratios have been measured in shells of the bivalve mollusk Saxidomus from eleven localities, ranging in age from modern to probably more than 500,000 yr, along the Pacific coast of North America. Natural logarithms of amino acid concentrations correlate...
First-order analysis of deformation of a thrust sheet moving over a ramp
Philip Berger, Arvid M. Johnson
1980, Tectonophysics (70) T9-T24
John L. Rich introduced the revolutionary concept that many folds in the Appalachian Mountains can be explained as superficial structures formed by passive translation of thrust blocks over ramps in detachment surfaces. The amount of layer-parallel shortening can be negligible in the formation of these folds. Rich primarily was concerned...

Coal GeologyThe Crumpler quadrangle lies in the Appalachian Plateaus province, with the coal bearing Pocahontas and New River Formations of Pennsylvanian age having a gentle dip toward the northwest. Coal bed maps were prepared (figures 1-7) and resources were estimated (table 1) for seven of the many coal beds in...
Selected water-level records for Oklahoma, 1979-80
Willard B. Mills, Dannie E. Spiser
1980, Open-File Report 80-975
A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for...
Breeding biology and relation of pollutants to black skimmers and gull-billed terns in South Carolina
Lawrence J. Blus, Charles J. Stafford
1980, Special Scientific Report - Wildlife 230
The breeding biology and relation of pollutants to black skimmers (Ryn chops niger) and gull-billed terns (Gelochelidon nilotica) were investigated in South Carolina from 1969 through 1975. With few exceptions, the two species nested together in colonies located on barrier islands. We located 10 colonies, 7 of which were on...

The Rocky Mountain population of the western Canada goose: Its distribution, habitats, and management
William B. Krohn, Elwood G. Bizeau
1980, Special Scientific Report - Wildlife 229
The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery patterns examined in this study and recovery data from other investigators. Habitat information obtained from nine cooperating wildlife agencies within the RMP's range provided...
