Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was purchased, effective use of this system...

Peritidal lithologies of Cambrian carbonate islands, Carrara Formation, southern Great Basin Peritidal lithologies of Cambrian carbonate islands, Carrara Formation, southern Great Basin
The Carrara Formation is a heterogeneous sequence of quartzites, siltstones, shales, limestones, dolostones, and mixed terrigenous-carbonate rocks. It is Early and Middle Cambrian in age (Stewart, 1970; Palmer, 1971). Figure 32-1 illustrates the general distribution of Carrara lithologies along a transect approximately normal to depositional strike (Fig. 32-2). The formation contains...

Earthquake mechanism and displacement fields close to fault zones: Report on the Sixth GEOP Research Conference Earthquake mechanism and displacement fields close to fault zones: Report on the Sixth GEOP Research Conference
The Sixth Geodesy/Solid Earth and Ocean Physics (GEOP) Research Conwas held on February 4–5, 1974, at the Institute of Geophysics and Planetary Physics, University of California, San Diego, in La Jolla, California. It was attended by about 100 persons. James N. Brune, program chairman, opened the conference and delivered the introductory address, a somewhat extended version of which is...

Geodetic determination of strain at the Nevada Test Site following the Handley event Geodetic determination of strain at the Nevada Test Site following the Handley event
Repeated surveys of a trilateration network (aperture greater than 20 km) centered on ground zero for the HANDLEY event, a nuclear explosion at the Nevada Test Site with yield in excess of 1 megaton, suggest that the explosion induced an east-west extension of the network by more than 50 mm. In the year following the detonation, this deformation reversed such that the final configuration

Effects of the Bear Valley and San Juan Bautista earthquakes of 1972 on Geodimeter line lengths Effects of the Bear Valley and San Juan Bautista earthquakes of 1972 on Geodimeter line lengths
Measurements of lines of the California Geodimeter network in the vicinity of the epicenters of four 1972 earthquakes (magnitudes 4.7, 4.7, 4.8, and 5.1) along the San Andreas fault system indicate that no significant anomalous changes in line length preceded or accompanied those earthquakes. Within the precision of measurement, the data are consistent with a linear change in line length...

Geophysical observations on northern part of Georges Bank and adjacent basins of Gulf of Maine Geophysical observations on northern part of Georges Bank and adjacent basins of Gulf of Maine
Continuous-seismic-reflection and magnetic-intensity profiles provide data for inferences about the geology of the northern part of Georges Bank and the basins of the Gulf of Maine adjacent to the bank. Basement is inferred to be mostly sedimentary and volcanic rocks of Paleozoic age that were metamorphosed and intruded locally by felsic and mafic plutons near the end of the Paleozoic...
