...Duryodhan Epili; George A. McMechan Abstract A 3-D prestack Kirchhoff migration is implemented and successfully applied to a 3-D data set from the Ouachita frontal thrust zone in southeastern Oklahoma. The algorithm uses data decomposition and operates efficiently both in multiprocessor vector...

...Dan M. Baker; Robert J. Lillie; Robert S. Yeats; Gary D. Johnson; Mohammad Yousuf; Agha Sher Hamid Zamin Abstract The Salt Range is the active frontal thrust zone of the Himalaya in Pakistan. Seismic reflection data show that a 1 km offset of the basement acted as a buttress that caused the central...

... by previous zones of weakness within the crust. Movement is principally dip-slip and latest movement appears to involve tearing on the northwest-trending fault set. Shortening by basement thrusting and associated folding is 20-25 km (12-15 mi). The other structural pattern is that of the frontal fold...

... rocks in the Nahan Thrust, in the vicinity of the Main Frontal Thrust that represents a tectonically active zone in the Himalayan orogen. The Nahan Thrust is characterized by alternating red and gray gouge layers, and a single black gouge layer. Our results from electron microscopy and X-ray...

..., and the rimming gravity maximum. MT signatures of the allochthonous Ouachita facies have been established with the aid of well control and are correlated along the traverse. Both conductive foreland facies and the underlying resistive Precambrian can be traced beneath the resistive frontal thrust zone, but become...

...Figure 5. Outcrop photographs of the Frontal Thrust zone taken during the Shinkai 6500 and KAIKO dives. (A) Brittle deformation of turbidite layers (see Fig. 12A ) (10K#43). (B) Brittle deformation of turbidite layers (for sample #755 R-002, see Fig. 12A ) (6K#755). ...

... shelf strata in the Frontal thrust zone. Toward the interior of the mountain belt, the Benton uplift is a broad antiform, apparently cored by crystalline basement at depths below 7 km (23,000 ft). Beneath the southern Ouachitas and the adjacent Gulf coastal plain, a zone of south-dipping reflections...

... include (from north to south) (1) triangle zones along the northern border of the frontal thrust zone produced by imbrication at depth, (2) large-scale (~ 10-km wavelength) fault-propagation folds in the frontal thrust zone, formed primarily above normal faults that offset the basement and act...

... thrust is estimated to be 500–900 m and the slip rates are 1.47–4.55 m ka –1 , corresponding to the highest class of active faults on land in Japan. During the surveys of the Tenryu frontal thrust zone, we discovered a new active fault scarp that was several tens of centimetres high, interpreted...

... the Paleozoic substratum argue for a Tertiary (Middle Eocene-Late Oligocene?) contractional reactivation of the fault network thereby documenting a repeated inversion process along the Artois Variscan thrust front. The Variscan frontal thrust zone is thus shown here to represent a prominent crustal-scale...

...Tomas R. Zapata; Richard W. Allmendinger ABSTRACT The frontal thrust zone of the Precordillera thrust belt of western Argentina only superficially resembles a classical Alberta-style triangle zone. In this thick-skinned triangle zone, the thrust front is the result of interaction between...

... lodes, termed "steep reefs." The kinematics and orientation of the mineralized shear zones are consistent with a lateral and frontal thrust zone geometry that formed during the Late Archean thrusting of the northern marginal zone onto the Zimbabwe craton. Gold is spatially and temporally closely...

... frontal thrust zone of southeast Oklahoma. Comparison of the 3-D field data with both viscoelastic and elastic response clearly demonstrates the importance of inclusion of viscoelasticity when accurate amplitude fitting is desired. Observed amplitude and traveltime variations can be explained by shallow...

... Reconstruction Technique (SIRT). The algorithm is applied to 3-D estimation of near-surface velocity and attenuation distributions from 3-D surface-survey field data from the Ouachita frontal thrust zone in southeastern Oklahoma; the images obtained correlate well with the known surface geology. Resolution...
