Book Description
Passive continental margins are formed within a single lithospheric plate in which the continental crust adjoins the oceanic crust. Assessment of the geological potential of these margins requires a comprehensive knowledge on the history of the ocean—from the time of pre-rifting events to the present. Tectonics of the Eastern Continental Margin of India presents the different aspects of a passive margin such as its evolution, tectonics, and associated hazards, taking the Eastern Continental Margin of India (ECMI) as a case study. It discusses the passive margin and focuses on its origin, morphology, structure, and exploration potential; describes the major structural lineaments delineated from the geophysical data over the ECMI; and attempts to explain the geodynamic evolution of this passive margin. A preliminary estimate on the seismic hazards associated with ECMI is also presented in the book.

Book Description
Developments in Geotectonics, Volume 20: Recent Crustal Movements, 1982 presents the proceedings of the 3rd Symposium on Recent Crustal Movements and Phenomena Associated with Earthquakes and Volcanism, held in Tokyo, Japan on May 12–13, 1982. This book presents the results in crustal movement studies at a local or regional scale. Organized into four parts encompassing 45 chapters, this volume begins with an overview of the gravimetric research carried out in various locations in Maracaibo Basin Area. This text then evaluates the reliability of the leveling measurements using modified geodetic checks as well as through comparison with independent measurements of crustal movement. Other chapters consider the basis of geodetic strain analysis. This book discusses as well the first-order geodetic measurements in seismically active areas in southern and southwestern Australia. The final chapter deals with the correlation of the data of relevelling with surface relief. This book is a valuable resource for engineers and geologists.

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.

Book Description
Developments in Geotectonics, 16: Recent Crustal Movements, 1979 covers the proceedings of the IUGG Interdisciplinary Symposium No. 9, ""Recent Crustal Movements"", held in Canberra, A.C.T., Australia on December 13-14, 1979. The book focuses on instruments and methods for the determination of crustal movements; methods of evaluating crustal movements; and interpretation of the crustal structure and crustal movements with the assistance of other geophysical data. The selection first offers information on the design and error characteristics of a fundamental global geodetic network; state and prospects of development of high-precision geodetic methods for studying crustal movements; and interferometric techniques for measuring horizontal earth crustal movements. The text then takes a look at the vertical crustal movements of the Carpatho-Balkan region and height changes and vertical crustal movements in Western German areas. Discussions focus on vertical movements map, instrumental improvements for the observation of vertical crustal movements, and map of height changes and vertical crustal movements. The text ponders on the episodic block motion and convergence along the Calaveras fault in central California and complete determination of local crustal deformation from geodetic observations. The selection is a valuable source of data for geologists and readers interested in crustal movements.

Book Description
Extensive field studies on the African and North American plates during this past decade have yielded a wealth of new data and ideas about rift basins and the origin of passive margins. New surface and subsurface basins have been identified; fossils abound in strata that only recently were considered barren; oil exploration is being actively pursued in continental strata of the Richmond-Taylorsville, Sanford and Newark basins, Late Triassic marine strata have been identified in Georges Bank off the coast of Massachusetts, and the roles of wrench tectonics, successor basins and listric normal faults have challenged the classical view that these are simple extensional basins.This two part work brings together representative examples of these studies. It is not intended as an exhaustive synthesis of the subject, but rather a vehicle to present new data, new ideas and alternative views. Some of the papers present regional summaries, others attempt to relate local features to regional questions, while others describe modern rift basins as possible analogs of early Mesozoic basins.Geologic data from the Atlantic passive margins record that continental rifting of central Pangaea occurred during the latest Triassic-earliest Jurassic (Liassic), and that sea-floor spreading probably began no later than the Middle Jurassic. The primary subject of this book focuses on the Triassic-Jurassic rifting events that led to the breakup of Pangaea and the opening of the central Atlantic Ocean. Whereas other treatises have focused on the origin of the passive margins, inferred primarily from geophysical data of the offshore basins, this volume primarily and uniquely focuses on land-based field studies of the onshore synrift basins. Offshore studies of synrift basins are also included and add substantially to our understanding of the breakup. However, the onshore data base, while complementary, is different, thus providing researchers with a different insight to the questions at hand.The book is organized into four sections. Section I, Pangaean Plate in Time and Space, first locates Pangaea in space and then places the Triassic basins within an historical context on the Alleghanian-Variscan Orogens. Section 2, the offshore and onshore basins of the North American and African Plates, comprises about 70% of all papers in this book, and includes papers on structural geology, petrology, paleontology, sedimentation, organic geochemistry, vulcanism and mineral resources. Section 3, Related Mesozoic Atlantic Rift Basins, includes papers on Iberia, Western Europe, the Benue Trough and Brazil. The final section of the book, Analogs, includes the rift basins of East Africa, the Red Sea, the Gulf of Elat (Aqaba), the Dead Sea and the Rio Grande.The book is richly illustrated throughout with figures, photographs, tables and fold-out maps, including nine in full colour.
