Growth and retreat of the West Antarctic Ice Sheet from the last glacial maximum to the present in the eastern Ross Sea, Antarctica
Marine geological evidence supports rapid retreat of the West Antarctic Ice Sheet in the eastern Ross Sea before the last glacial maximum. As the only accessible marine record of a major drainage outlet of the West Antarctic ...
Sediment microstructures and deformation at the toe of the Nankai accretionary prism: Effects of accretion and diagenesis, and evolution of the decollement
Sediments incorporated into accretionary prisms experience significant changes in physical properties, grain fabric, and diagenesis. The record of such changes is preserved in sediment microstructures. Scanning electron ...
Near-surface seismic reflection investigations at a groundwater contamination site
A 3-D seismic reflection survey was conducted at a groundwater contamination site to adequately image the near surface (<20m) at a level of detail to enhance ongoing remediation activities at the site. The site, Operable ...
The Paleocene of La Concepcion Field (Maracaibo Basin, Venezuela): Transition from Andean to Caribbean active margin
The Paleocene Guasare Formation of La Concepcion Field (Maracaibo Basin, Venezuela) consists of thin carbonates that were deposited in a dynamic near-shore marine setting greatly influenced by terrestrial siliclastics and ...
Linking climate, sea level, and sedimentary response on the Texas shelf and upper slope: Examples from the Brazos and Colorado fluvial-deltaic systems
A 2D high-resolution seismic grid was combined with cores to develop a stratigraphic model of the East Texas shelf and slope, which showed that fluvial deltaic systems do not significantly impact upper slope stratigraphic ...
Investigation on the generation of primitive basalts in the southern Washington Cascades
An investigation of the petrography, mineralogy and chemistry of primitive basalts found in a E-W transect of southern Washington and northern Oregon provides constraints concerning the thermal structure and composition ...
