Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: August 1979 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: August 1979
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Compilation of strong-motion records from the August 6, 1979 Coyote Lake earthquake Compilation of strong-motion records from the August 6, 1979 Coyote Lake earthquake
This report represents a joint effort by the OSMS, CDMG and the U.S. Geological Survey (USGS). The report summarizes all strong-motion accelerograph records recovered from the August 6, 1979 Coyote Lake earthquake. The majority of accelerograms were recorded at stations operated by the OSMS-CDMG and USGS; the latter organization operates a network of instruments that belong to various...

A large landslide on Mars A large landslide on Mars
A large landslide deposit on the south wall of Gangis Chasma contains at least 100 billion m3of material that moved 60 km across the trough floor at a speed of more than 100 km/hr. The deposit consists of slump blocks at the head, hummocky material farther out, and a vast apron of longitudinally ridged material extending to the toe. The landslide deposit resembles many terrestrial ones...

Estimating pore and cement volumes in thin section Estimating pore and cement volumes in thin section
Point count estimates of pore, grain and cement volumes from thin sections are inaccurate, often by more than 100 percent, even though they may be surprisingly precise (reproducibility + or - 3 percent). Errors are produced by: 1) inclusion of submicroscopic pore space within solid volume and 2) edge effects caused by grain curvature within a 30-micron thick thin section. Submicroscopic...

Factors controlling heavy-mineral variations on the South Texas outer continental shelf, Gulf of Mexico Factors controlling heavy-mineral variations on the South Texas outer continental shelf, Gulf of Mexico
Heavy-mineral distribution on the outer continental shelf off the southern coast of Texas shows regional variability induced by provenance and local variability reflecting genetic differences in sea-floor sediments. Q-mode factor analysis showed that three suites of heavy minerals are present. The southern ancestral Rio Grande delta sediments contain a distinct opaque-pyroxene-garnet...
