Southern Oklahoma and adjacent parts of Texas contain an extensive igneous province
emplaced during Early Cambrian rifting within the Southern Oklahoma rift zone. The rift zone …

Seismic migration is the process by which an acoustic seismic wavefield, containing
scattered/diffracted waves recorded as a function of time, is converted into a focussed image …

ABSTRACT The Anadarko basin of Oklahoma is a two-stage Paleozoic cratonic basin with
as much as 12 km (7.5 mi) or more of sedimentary fill. We present a present-day thermal …

Two‐dimensional velocity distributions may be estimated using iterative tomographic
imaging. The medium is parameterized as a grid of small rectangular elements, each of …

Through the use of iterative turning-ray tomography followed by wave-equation datuming (or
tomo-datuming) and prestack depth migration, we generate accurate prestack images of …

Recent applications of 2D and 3D turning-ray tomography show that near-surface velocities
are important for structural imaging and reservoir characterization. For structural imaging, we …

Publisher Summary This chapter deals with the Southern Oklahoma aulacogen, which is a
major structural element of interior North America. As a rift, this feature involved extensive …

Abstract Knowledge of the midcontinent crustal structure of North America is crucial for
understanding the evolutionary history of the ancient North American craton as Laurentia …

Wide-angle seismic profiles reveal anomalously thick crust with a high-velocity (> 7.3 km s−
1) zone under the Sierra Leone Rise, a major mid-plate elevation in the Atlantic lying …

Full-wavefield inversion of two-component (elastic), wide-aperture, seismic data from
surface sources and receivers simultaneously provides 2-D estimates of both P and SV …
