This dissertation consists of three chapters describing seismic stratigraphic studies in three very different continental margin settings. The first chapter discusses the northwestern Ross Sea, the second discusses the ...

The nature of the basement underneath the Monagas foothills and the Serrania del Interior of the Eastern Venezuela Basin is unknown. It could consist of crystalline Precambrian, Paleozoic sedimentary rocks and/or Jurassic ...

An integrated model is derived for the sequential development of tectonic events in time among different evolving component structural domains comprising the central Walker Lane, west-central Nevada, based on constraints ...

Subduction of an oceanic plate beneath the Bering Strait region resulted in the formation of an extensive magmatic belt along the margin of the region during the Cretaceous. Plutons and gneiss domes of this age are broadly ...

On the northeastern offshore Venezuela, the pre-Tertiary basement consists of a deeply subducted accretionary complex of a Cretaceous island arc system that formed far to the west of its present location. The internal ...

The Clementine Mission acquired the first global compositional data for the Moon. Five discrete wavelengths (415, 750, 900, 950, 1000 nm) span the ultraviolet-visible spectrum. Using this data, I have performed a systematic ...

Analyses of Oregon Cascades basalts reveal two groups of High Cascades (9-0 Ma) lavas: (1) "enriched" basalts with high Ba, Sr, Ba/Nb, and Ba/La, and (2) "depleted" basalts with flat rare earth element patterns and relatively ...

Pedro Channel is the deepest, central-most seaway on the northern Nicaragua Rise. A revised bathymetric map illustrates a seafloor dissected by numerous canyons and gullies as well as portions of a drowned carbonate bank ...

A seismic and sequence stratigraphic investigation of the Rio Grande system provides information conceming: (1) the distribution of depositional units relative to the last glacio-eustatic cycle (120,000 ybp to present); ...

Seismic techniques and tools have not routinely been transferred to ground-penetrating radar (GPR) studies due to computational, financial, and logistical limitations. A simple processing package was developed to aid in ...
