1979 annual index of current earthquake literature
M.L. Gunn, B.S. Hayashida, William Hung Kan Lee
1980, Open-File Report 80-238
In the past several years, earthquake research has been greatly accelerated in China, Japan, USSR and the United States. Presently, about 3,000 earthquake-related publications (including meeting abstracts) are produced yearly. In order to keep up with this current literature, a computer-based bibliographic system was implemented as part of a research...
Revised nomenclature and stratigraphic relationships of the Fredericksburg Complex and Quantico Formation of the Virginia Piedmont
Louis Pavlides
1980, Professional Paper 1146
The Fredericksburg Complex, in part a migmatitic terrane in northeast Virginia, is subdivided on the basis of lithology, as well as aeromagnetic and aeroradiometric data, into two metamorphic suites. These suites are separated by the northeast-trending Spotsylvania lineament, a rectilinear geophysical feature that is probably the trace of an old...
Minisparker profiles from Jeffreys Ledge and adjacent areas in the western Gulf of Maine
Diane M. Eskenasy, Norman G. Bailey
1980, Open-File Report 80-320
A total of 250 kilometers of single-channel seismic-reflection data (28 minisparker profiles) were collected in the coastal waters of Massachusetts, north of and immediately south of Cape Ann, and on the western flank of Jeffreys Ledge, western Gulf of Maine, during the September 1978 cruise of the R/V ASTERIAS. The...
Quantitative analysis versus semiquantitative optical emission spectrographic analysis of chromium, nickel, zinc, vanadium, and molybdenum in organic-rich Paleozoic marine strata, Western United States
George A. Desborough, F. G. Poole, Edwin K. Maughan, H.L. Groves, Gregory N. Green
1980, Open-File Report 80-1271
Comparison of analytical results between the quantitative method and the semiquantitative six-step optical-emission spectrographic method commonly shows significantly lower values for the semiquantitative method. The lower values are most obvious for splits from the same samples of fine-grained organic-rich rocks where the concentrations of the metals chromium, nickel, zinc, vanadium,...
Physical and chemical properties of the Potomac River and environs, August 1978
Richard E. Smith, Raynol E. Herndon
1980, Open-File Report 80-746
Basic data on the physical and chemical properties measured over the period 21 August through 31 August 1978 on the tidally influenced Potomac River and estuary are presented herein. Forty-two vertical profiles, and approximately 170 surface observations were made of the distributions of salinity, temperature, light transmission, chlorophyll-a fluorescence, dissolved...
