Foredeep and thrust belt interpretation of the Maturin Sub-Basin, Eastern Venezuela Basin
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 ...
Petrogenesis of plutons and hypabyssal rocks of the Bering Strait region, Chukotka, Russia
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 ...
Trace element geochemistry of basalts from the Oregon Cascade Range: Implications for magma generation and possible variations in the sub-arc mantle
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 ...
Application of seismic tools and techniques to ground-penetrating radar (GPR) studies
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 ...
Late Quaternary highstand and transgressive deltas of the ancestral Colorado River: Eustatic and climatic controls on deposition
Deltaic deposits were the main sinks for sequestering large volumes of sand on the northern Gulf of Mexico continental shelf during the late Quaternary. Examination of high resolution seismic reflection data, cores, and ...
