Correlations between seismic wave velocities and physical properties of near-surface geologic materials in the southern San Francisco Bay region, California
Thomas E. Fumal
1978, Open-File Report 78-1067
To identify geologic units with distinctly different seismic responses for the purposes of seismic zonation, compressional and shear wave velocities have been measured in boreholes at 59 sites in the San Francisco Bay region in a wide range of near-surface (0-30m) geologic materials. Several physical parameters, which can be readily...
The structure and stratigraphy of the Pen Argyl Member of the Martinsburg Formation in Lehigh and Berks counties, Pennsylvania
Gary George Lash
1978, Open-File Report 78-391
The Pen Argyl Member, the upper claystone slate member of the Martinsburg Formation, was studied in three quadrangles in Lehigh and Berks Counties, Pennsylvania. Graptolites collected from the Pen Argyl Member at Lehigh Gap indicate a lower Upper Ordovician (Edenian-Maysvillian) age for the Pen Argyl Member. The Pen Argyl Member...
Principal facts for gravity observations in the Coso Hot Springs area, California
William F. Isherwood, Donald Plouff
1978, Open-File Report 78-298
Gravity observations were made at 292 locations in the Coso Hot Springs area, California (figs. 1 and 2). The field work was completed during June 1976 by William F. Isherwood and Jerry H. Hassemer using LaCoste-Romberg Gravity Meters G-131 and G-159. The purpose of the gravity survey is to provide...
FORTRAN programs for calculating nonlinear seismic ground response in two dimensions
W. B. Joyner
1978, Open-File Report 78-287
The programs described here were designed for calculating the nonlinear seismic response of a two-dimensional configuration of soil underlain by a semi-infinite elastic medium representing bedrock. There are two programs. One is for plane strain motions, that is, motions in the plane perpendicular to the long axis of the structure,...
Implementation plan for Bolivian Mineral Exploration Fund
Harold Kirkemo
1978, Open-File Report 79-597
Bolivia ranks second among world producers of tin and antimony, and first in bismuth production. Mineral exports in 1975 were valued at $314.2 million, nearly 60 percent of the value of all exports, and petroleum product exports totalled nearly $157 million, or 30 percent of the total. Tin accounted for...
Analyses and description of geochemical samples, Mill Creek Wilderness Study Area, Giles County, Virginia
Leung Mei, Frank Gardner Lesure
1978, Open-File Report 78-1077-D
Semiquantitative emission spectrographic analyses for 64 elements on 62 stream sediment and 71 rock samples from Mill Creek Wilderness Study area, Giles County, Virginia, are reported here in detail. Locations for all samples are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks...

Water resources data for Georgia, water year 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report GA-77-1
Water resources data for the 1977 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs. This report contains discharge records for 100 gaging stations; stage for 9 gaging stations; stage and contents for 16 lakes and reservoirs;...
Longitudinal turbidity structures in a bar-built coastal plain estuary, Corpus Christi Bay, Texas
Gerald L. Shideler
1978, Open-File Report 78-789
Corpus Christi Bay is a shallow, bar-built variety of estuary that is characteristic of the South Texas Coastal Plain. On the basis of synoptic in situ measurements of light transmissivity and suspended-sediment concentrations at six monitoring stations, a time sequence of six turbidity structures was established along the longitudinal trend...
Water resources data for Mississippi, water year 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report MS-77-1
Water resources data for the 1977 water year for Mississippi consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels of wells. This report contains discharge records for 85 gaging stations; stage records for 15 of these...
