This book was released on 2019 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last 30 million years, the Southern California plate boundary has transitioned from a region of plate collision and subduction to a right-lateral translational boundary. This transition created many of the geologic features that are observed today along the Inner California Borderlands (ICB), including the Western Transverse Range Province (WTR). The WTR has long been considered a large coherent block (~200 by 100 km) that underwent 90-100 degrees of clockwise rotation in the early Neogene as a result of right-lateral transform motion along the margin in a process characterized as "book-shelf" faulting. Directional paleomagnetic data have been employed to support the hypothesis of coherent rotation of 'books', here referred to as a 'large coherent block'. As the data collected in this region vary in quality, age, and locality, we set out to test how well the data support the large coherent block rotation hypothesis of the WTR when viewed as a composite. If the large coherent block rotation model is correct, it predicts the paleomagnetic directions of the same age within the WTR should record the same amount of rotation. To test this, we have compiled a large set of directional paleomagnetic data from relevant published papers, updating the age constraints to a consistent time scale where possible. By re-examining directional paleomagnetic data from same-age rocks within the WTR, our compilation shows different amounts of rotation across the WTR from formations that are similar in age. The directional paleomagnetic data are therefore inconsistent with the prediction of a large coherent block rotation model. We propose an alternative model for the deformation of the WTR, one that is consistent with paleomagnetic data from the region. In our model, rather than a single large block rotating coherently, many micro-plates that range from kilometers to tens of kilometers rotated individually, accommodating numerous right-lateral fault displacement. Our analog for the deformation of the WTR is a garnet schist, where the "garnets" are the microplates rotated by bounding right-lateral shear zones.

Download or read book Geological Monitoring written by Rob Young and published by Geological Society of America. This book was released on 2009 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Geologic Monitoring is a practical, nontechnical guide for land managers, educators, and the public that synthesizes representative methods for monitoring short-term and long-term change in geologic features and landscapes. A prestigious group of subject-matter experts has carefully selected methods for monitoring sand dunes, caves and karst, rivers, geothermal features, glaciers, nearshore marine features, beaches and marshes, paleontological resources, permafrost, seismic activity, slope movements, and volcanic features and processes. Each chapter has an overview of the resource; summarizes features that could be monitored; describes methods for monitoring each feature ranging from low-cost, low-technology methods (that could be used for school groups) to higher cost, detailed monitoring methods requiring a high level of expertise; and presents one or more targeted case studies."--Publisher's description.

Download or read book Paleomagnetic Rotations and Continental Deformation written by Catherine Kissel and published by Springer. This book was released on 2011-09-26 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most interesting results obtained in the last two decades in the study of crustal deformation has been the recognition that large regions of continental crust undergo rotations about vertical axis during deformation. Proof of such rotations has come through the paleomagnetic studies, which reveal rotations when paleomagnetic declinations within the deforming region arc compared with those found in coeval rocks in the stable regions outside the deforming zone. Such rotations were first described in Oregon then in the North American Cordilleras and in Southern California and were a surprise to everyone. Even in California which, as a result of oil exploration, was among the best geologically explored regions in the world, no one could claim to have predicted that these rotations would be found. Rotations have subsequently been found in other areas of recent continental tectonic activity, notably in the Basin and Range province, New Zealand, the Andes, Greece and Western Turkey, so that they appear as an important feature of continental deformation.
Download or read book Fundamentals of Geomorphology written by Richard John Huggett and published by Routledge. This book was released on 2011-03-15 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.
