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...

The Aleutian Basin, Bering Sea a frontier area for hydrocarbon exploration The Aleutian Basin, Bering Sea a frontier area for hydrocarbon exploration
The Aleutian Basin is the deep water (>3000 m) basin that lies north of the Aleutian Islands adjacent to the Bering Sea continental shelf. The basin, about the size of the state of Texas, is underlain by a 2-9 km-thick flat-lying sequence of mostly Cenozoic sediment and rock that includes diatomaceous silty clay interbedded with turbidities in the upper 1 km. Before 1974, geologic and...

Age of graben systems on the moon Age of graben systems on the moon
The study focuses on the time of formation of the graben. An attempt is made to determine whether the graben are restricted to geologic units of certain ages, and whether and at what time graben formation ceased. It is shown that (1) most preserved graben formed considerably later than the impacts that formed the basins; (2) graben are faults that are reactivated along older basin...

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1978 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1978
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.

Playback Station #2 for Cal Net and 5-day-recorder tapes Playback Station #2 for Cal Net and 5-day-recorder tapes
A second system (Playback Station #2) has been set up to play back Cal Net 1" tapes and 5-day-recorder 1/2" tapes. As with the first playback system (Playback Station #1) the tapes are played back on a Bell and Howell VR3700B tape deck and the records are written out on a 16-channel direct-writing Siemens "0scillomink." Separate reproduce heads, tape guides, and tape tension sensor...

FORTRAN programs for calculating nonlinear seismic ground response in two dimensions FORTRAN programs for calculating nonlinear seismic ground response in two dimensions
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, and the other is for antiplane strain motions, that is...
