Available in PDF, EPUB and Kindle. Book excerpt: "This volume contains a comprehensive, worldwide history of seismological studies of the Earth's crust using controlled sources from 1850 to 2005. Essentially all major seismic projects on land and the most important oceanic projects are covered. The time period 1850 to 1939 is presented as a general synthesis, and from 1940 onward the history and results are presented in separate chapters for each decade, with the material organized by geographical region. Each chapter highlights the major advances achieved during that decade in terms of data acquisition, processing technology, and interpretation methods. For all major seismic projects, the authors provide specific details on field observations, interpreted crustal cross sections, and key references. They conclude with global and continental-scale maps of all field measurements and interpreted Moho contours. An accompanying DVD contains important out-of-print publications and an extensive collection of controlled-source data, location maps, and crustal cross sections."--Publisher's description.

Download or read book Seismic Profiling Constraints on the Evolution of the Brooks Range Arctic Alaska from an Integrated Reflection refraction Survey written by Eugene S. Wissinger and published by . This book was released on 1996 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated vertical incidence to wide-angle seismic data set has been used to develop a consistent migrated seismic reflection image and seismic velocity model of the Brooks Range fold and thrust belt in north central Alaska. Common midpoint (CMP) reflection data image the principal structures comprising the Brooks Range: the Endicott Mountains allochthon (EMA), the crustal scale Doonerak duplex, the master detachment, a 1.0-1.5 sec thick zone of lower crustal reflectivity just above the crust-mantle boundary, and a complex crustal root. The master detachment separates the crust into units which have been uplifted and deformed in the fold and thrust belt from those which have not. Least squares inversion of both reflected and refracted travel time data produced a velocity model consistent with CMP images of the Brooks Range, Bouguer gravity data, and seismic velocities determined from petrophysical data. Maximum crustal thickness in the range is 49 km, in an asymmetric root located under the EMA. At the root, an offset in lower crustal reflectivity is observed along with two deep zones of reflections north of the root. These reflections are interpreted as a Moho offset of some 5 km, resulting from subduction of the Brooks Range lower crust northward beneath the North Slope. The seismic reflection data, velocity data, and surface geologic constraints are used to identify the boundaries of major structural assemblages in the Brooks Range and restore 3 interpretations of the range to their pre-Jurassic configurations. Minimum shortening estimates derived above the basal decollement for the 3 models approximate 500-600 km of Mesozoic-Recent shortening. The amount of sub-decollement shortening may be as little as that now observed, 50-65 km, or may be comparable to the 500-600 km observed for upper-intermediate crustal rocks. Proximity of the continental subduction zone to the crustal scale Doonerak duplex suggests that the development of the fold and thrust belt has been at least partially controlled by lower crust/mantle subduction.
