Recent Crustal Movements, 1977


Book Description

Recent Crustal Movements, 1977 is a compilation of the proceedings of the Sixth International Symposium on Recent Crust Movements. This volume is comprised of 50 papers and 38 abstracts, in addition to a special report about the RCM Symposium and the report of the Fennoscandian Subcommission. This volume is subdivided into eight parts. The first part presents the opening remarks at the symposium and the special report of the Fennoscandian Subcommission of the Commission on Recent Crustal Movements. Locations included in this report are the Estonian Soviet Socialist Republic, Finland, Sweden, Denmark, and Norway. Part two is about crustal deformation using extra-terrestrial geodesy. Part three explores the measurement of strain, tilt and gravity. The observed vertical crustal deformation is the focus of the fourth part. The second half of this volume focuses on geologic studies of Holocene deformation; observed horizontal crustal deformation; seismology; and, finally, experimental and theoretical models of interferometric methods for the measurement of distance in the study of recent crustal movements.




Recent Crustal Movements, 1979


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.




Recent Crustal Movements, 1982


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.










Crustal Properties Across Passive Margins


Book Description

Developments in Geotectonics, 15: Crustal Properties across Passive Margins covers the papers presented at the symposium ""Crustal Properties across Passive Margins"", held at Dalhousie University in Halifax, Nova Scotia on June 19-23, 1978. The book focuses on theoretical modelling of the rheological properties in the upper mantle beneath oceans and continents and stratigraphic studies of the sedimentary basins. The selection first offers information on seismic refraction study of the continental edge off the Eastern United States and gravity field of the U.S. Atlantic continental margin. Topics include crustal sections, inner and outer quiet zones, alternative models and complications, gravity models, free-air anomaly map, and the ocean-continent transition zone. The text then takes a look at the geologic history of the passive margin off New England and the Canadian Maritime Provinces and geophysical observations bearing upon the origin of the Newfoundland Ridge. The manuscript elaborates on the age and origin of the deepest correlative structures recognized off Canada and Europe and geophysical transects of the Labrador Sea. Discussions focus on magnetics and gravity, stratigraphic control, consequences regarding subduction or rifting, and deep structures of the Grand Banks of Newfoundland. The selection is a dependable reference for readers interested in crustal properties across passive margins.







Mechanism of Graben Formation


Book Description

Developments in Geotectonics, 17: Mechanism of Graben Formation covers the papers of an ICG Symposium held during the 17th IUGG General Assembly in Canberra, Australia on December 5, 1979. The book focuses on the formation, behavior, and mechanisms of grabens. The selection first offers information on crustal doming and the mechanism of continental rifting, mechanisms of continental riftogenesis, and thermal regimes, mantle diapirs, and crustal stresses of continental rifts. The text then ponders on crustal uplift and the propagation of failure zones and parameterized rift development and upper mantle anomalies. The publication surveys the continental rift system of the Rhinegraben-structure, physical properties, and dynamical processes and an example of the intrusion of asthenospheric material into the lithosphere as the cause of disruption of lithospheric plates. Regional stress field and rifting in Western Europe and the nature of greenstone belts in the Precambrian are also discussed. The selection is a dependable source of information for geologists and readers interested in the formation of grabens.
