Converted modes in subsalt seismic exploration
Salt has unusual properties which complicate seismic exploration. A Model study examines some problems encountered in subsalt amplitude analysis and demonstrates that traditional techniques for detecting hydrocarbons and ...
Pliocene-Pleistocene depositional sequences of the northern Gulf of Mexico, offshore Texas and Louisiana
This work tests the consistency of sequence stratigraphic methods by comparing the model documented in this study with previous models for growth faulted, siliciclastic environments. Interpretations derive from sequence ...
Kinematic analysis of the deformational structures on eastern Isla de Margarita, Venezuela
Because of its strategic location at the intersection of three regional trends, a kinematic study of the deformation on Isla de Margarita was undertaken to provide additional constraints for Caribbean plate tectonic models. ...
Finite-difference seismic wave modeling including surface topography
I present synthetics of seismic wave propagation near free surface topography. The velocity-stress formulations of both the full elastic and viscoelastic wave equations are used, and I have derived exact boundary conditions ...
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 ...
