This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The convergent margin of southern Alaska is considered one of the type areas for understanding the growth of continental margins through collisional tectonic processes. Collisional processes that formed this margin were responsible for multiple episodes of sedimentary basin development, subduction complex growth, magmatism, and deformation. Two main collisional episodes shaped this Mesozoic-Cenozoic continental margin. The first event was the Mesozoic collision of the allochthonous Wrangellia composite terrane. This event represents the largest addition of juvenile crust to western North America in the past 100 m.y. The second event is the ongoing collision of the Yakutat terrane along the southeastern margin of Alaska. This Cenozoic event has produced the highest coast mountain range on Earth (Saint Elias Mountains), the Wrangell continental arc, and sedimentary basins throughout southern Alaska. Active collisional processes continue to shape the southern margin of Alaska, mainly through crustal shortening and strike-slip deformation, large-magnitude earthquakes, and rapid uplift and exhumation of mountain belts and high sedimentation rates in adjacent sedimentary basins. This volume contains 24 articles that integrate new geophysical and geologic data, including many field-based studies, to better link the sedimentary, structural, geochemical, and magmatic processes that are important for understanding the development of collisional continental margins."--Publisher's website.
Download or read book Continental Lower Crust written by David Fountain and published by Elsevier Publishing Company. This book was released on 1992 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. This is a multi-disciplinary review of the current state of geological and geophysical research on the continental lower crust. Topics include the structure of the crust as deduced from geophysical research, rheology of the lower crust, composition and evolution of the lower crust as constrained by xenoliths, magmas, crustal cross-sections, the role of fluids in the crust, and the interaction of the lower crust and magmas. Each chapter has extensive reference lists.The audience for this book is diverse. One group will consist of newcomers (students and professionals) to lower crustal research who are looking for an overview of the current research. For this group, the present volume can serve as a point of departure for further investigation of the continental lower crust. A second audience will consist of active researchers interested in reviews of aspects of lower crustal researchers out of their discipline. These scientists will find t

This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Border Ranges Fault System (BRFS) bounds the Cook Inlet and Susitna Basins, an important petroleum province within south-central Alaska. A primary goal in the research is to test several plausible models of structure along the Border Ranges Fault System using a novel three-dimensional inversion utilizing gravity and magnetic data, constrained with other geophysical, borehole and surface geological information. This research involves the development of inversion modeling software using a Borland C++ compiler as part of the Rapid Application Development (RAD) Studio. The novel inversion approach directly models known geology, and a priori uncertainties on the geologic model to allow researchers to compare alternative interpretations. This technique to evaluate three-dimensional structure in regions of extremely complex and poorly known geology can be applied in other studies of energy resources. The software reads an ASCII text file containing the latitude, longitude, elevation, and Free Air anomalies of each gravity station as well as known gridded surface files of known topography and subsurface units. The contributions of each node in the grid are computed in order to compare the theoretical gravity calculations from a forward model to the gravity observations. The computation of solutions to the linearized inversion yields a range of plausible densities. The user will have the option of varying the body proportions or densities to observe changes in gravity.
