Geodynamics of Rifting


Book Description

This volume contains papers giving an interdisciplinary review of 12 major rift systems from North and South America, Africa, Europe and Asia. These papers are written by an international group of academic and industrial specialists each of whom is most knowledgeable about the respective rift. The analyzed rifts were selected on the basis of availability of an as-complete-as-possible geological and geophysical data base. Thirteen papers deal with geodynamic processes governing the evolution of rifts.A comprehensive digest of the available stratigraphic, structural, geophysical and petrological data, together with an extensive list of references, is provided for each of the analyzed rift systems. The megatectonic setting and dynamics of evolution of each basin is discussed. Geodynamic models are tested against the record of the analyzed rifts.The question of "active" as against "passive" rifting is addressed. The rifts analyzed range in age from Precambrian to Recent and cover a wide spectrum of megatectonic settings. There is discussion of the evolution of rifts in a plate-tectonic frame. The case histories are followed by discussions addressing the global setting of rifts and geodynamic processes active during the development of rifted basins.

Continental and Oceanic Rifts


Book Description

Published by the American Geophysical Union as part of the Geodynamics Series, Volume 8. During the past decade of the International Geodynamics Program many publications dealing with specific rift areas of the Earth's surface have appeared. Most of them followed symposia that were held in the respective rift zones. Among the rifts thus treated are the Rhinegraben, Afar, Iceland, the Baikal rift, the Oslo paleorift, the Rio Grande rift and the Dead Sea rift. Furthermore, publications dealing with studies of the ocean floor have discussed many oceanic rift areas.




The East African Rift System


Book Description

The East African Rift System: Geodynamics and Natural Resource Potentials provides state-of-the-art knowledge and skills on how to explore, model, and extract the resources, using the East African Rift System (EARS) as a model. Each aspect to be discussed in the East African Rift System shall have its equivalent case study and readers interested in each rift of the world will find something connected or linked to his/her rift system of interest, be it a sub-chapter on earthquakes, geothermal energy models, etc. The East African Rift System: Geodynamics and Natural Resource Potentials also describes rifting models of all other known rifts (especially continental rifts) of the world such as the Basin and Range Province, Rio Grande (USA); Rhine Graben (France and Germany); the Tibetan Rohai (Tibet); the Shaanxi Bohai (China); Lake Baikal (Russia); North Island (Australia); and the Aegean Sea Rift (Turkey). Key aspects to be presented shall be: rift type, rift age, rift physical dimensions, geothermal gradient models, natural resources, and models of exploration. - Connects the science of rift systems to their economic potentials using the East African Rift System as the prime example - Includes discussions and case studies from rift systems around the world - Features chapters dedicated to natural resources, such as mineral deposit types (Au, He, REE, U) and the basic principles of their exploration?




Dynamics of Plate Interiors


Book Description

Published by the American Geophysical Union as part of the Geodynamics Series, Volume 1. The focus of the International Geodynamics Project, 1970–1979, was the movements of the surface and upper part of the earth's interior and it was recognized that most of the deformation occurs along narrow belts between the lithospheric plates. Also important to understanding earth process were those motions, primarily vertical that occurred within the plates, remote from plate boundaries. For this reason one of the 10 working groups set up in 1971 was working group 7 with the title "Eperogenic movements of regional extent" under the chairmanship of Dr. J. Tuzo Wilson. In 1974, after Dr. Wilson resigned following his retirement as Principal of Erindale College, University of Toronto, the Bureau of the Inter-Union Commission on Geodynamics appointed Dr. R. I. Walcott as chairman and the name of his working group was changed to "Dynamics of Plate Interiors". The objective of its programme was to determine the nature and origin of the dynamics of the more stable regions of the earth.

Geodynamics of the Eastern Pacific Region, Caribbean and Scotia Arcs


Book Description

Published by the American Geophysical Union as part of the Geodynamics Series, Volume 9. After a decade of intense and productive scientific cooperation between geologists, geophysicists and geochemists the International Geodynamics Program formally ended on July 31, 1980. The scientific accomplishments in more than seventy scientific reports and in this series of Final Report volumes. The concept of the Geodynamics Program, as a natural successor to the Upper Mantle Project, developed during 1970 and 1971. The International Union of Geological Sciences (IUGS) and the International Union of Geodesy and Geophysics (IUGG) then sought support for the new program from the International Council of Scientific Unions (ICSU). As a result the Inter-Union Commission on Geodynamics was established by ICSU to manage the International Geodynamics Program.




Continental Rifts: Evolution, Structure, Tectonics


Book Description

This multi-author book has been prepared by an international group of geoscientists that have been active in rift research since the late 1960s. In 1984, an informal, grass-roots study group was initiated to compare individual research results and to explore in greater depth the apparent differences and similarities in the interpretations from various rift systems. The group became known as the CREST working group, an acronym of Continental Rifts: Evolution, Structure and Tectonics, which not surprisingly became the title of this book.Continental Rifts: Evolution, Structure, Tectonics presents an overview of the present state of understanding and knowledge of the processes of continental rifting from a multidisciplinary, lithospheric scale perspective. The chapters have been structured on each rift system in approximately the same synoptic sequence, so as to facilitate comparisons of rifts by the reader. The book complements its predecessors by presenting a more unified picture. It succeeds in presenting the status of a representative majority of the continental rift systems that have been at the forefront of recent research. For students and experienced researchers alike, this book will be of significant value in assessing the current state of knowledge and in serving as a framework for future research.
