دانلود کتاب Deep Structure and Past Kinematics of Accreted Terranes

About The ProductPublished by the American Geophysical Union as part of the Geophysical Monograph Series. The concept of "accreted terranes," that continents grow by the addition of displaced fragments of crust, was the central topic of a recent multidisciplinary symposium sponsored by the International Union of Geodesy and Geophysics (IUGG). This volume contains a selection of papers presented in Symposium 12 at XIX General Assembly of the IUGG, held August 15-18, 1987, in Vancouver. Convenors Edward Irving and David Stone focused the program on two major themes. The first was to track the displacement of terranes using paleomagnetism, geologic mapping, and paleontology. The second theme was to explore the deep structure of accreted terranes using seismological, geochemical, and potential-field methods. Given the scope of those topics, it is no surprise that the participants represented many specialties within the field of solid-earth geophysics. The program included case histories from a collection of fold belts spanning much time and long distances, from the Proterozoic sutures of North America to the Cenozoic accretionary complexes of the Pacific rim.
