Download or read book Geology of the Pacific Northwest written by William N. Orr and published by Waveland Press. This book was released on 2006-12-04 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geologic history of the Pacific Northwest is as unique as the region itself. Created via tectonic plate movements and accretionary events, the original terranes were subsequently covered by sedimentary layers, ash, lavas, and glacial debris. These processes, begun millions of years ago, continue to affect the area, as seen in the eruption of Mount St. Helens and catastrophic Japanese tsunamis created by earthquakes in the Pacific Northwest. Understanding of the regions geology has led to new insight in volcanic eruption prediction, disaster preparedness, the environmental effects of mining, and urban development as it relates to geologic hazards. The Orrs detailed and informative writing style appeals to those with geologic training as well as beginners with an interest in the region. Each chapter covers a specific subregion, allowing for maximum flexibility both in the classroom and for the casual reader. The authors central theme that continental plate tectonics are the fundamental processes of Northwest geologic history permeates throughout the book.
Download or read book Floods Faults and Fire written by Peter L. Stelling and published by Geological Society of America. This book was released on 2007-01-01 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ten geological field guides presented in this volume explore key areas of the geologist's paradise that is Washington State and British Columbia. These trips investigate a wide variety of geological and geographical terrains, from the dry steppe of the channeled scablands and Columbia River basalt group to the east, across the glaciated and forested Cascade arc and Coast Mountains, to the geologically complex islands in the west. This guidebook may be unique in that four of the trips utilize boats to reach remote field areas and are therefore rarely visited by geologists.

Available in PDF, EPUB and Kindle. Book excerpt: The Puget Sound is a complex fjord-estuary system in Washington State that is connected to the Pacific Ocean by the Juan de Fuca Strait and surrounded by several large population centers. The watershed is enormous, covering nearly 43,000 square kilometers with thousands of rivers and streams. Geological forces, volcanos, Ice Ages, and changes in sea levels make the Sound a biologically dynamic and fascinating environment, as well as a productive ecosystem. Human activity has also influenced the Sound. Humans built several major cities, such as Seattle and Tacoma, have dramatically affected the Puget Sound. This book describes the natural history and evolution of Puget Sound over the last 100 million years through the present and into the future. Key Features Summarizes a complex geological, geographical, and ecological history Reviews how the Puget Sound has changed and will likely change in the future Examines the different roles of various drivers of the Sound’s ecosystem function Includes the role of humans—both first people and modern populations. Explores Puget Sound as an example of general bay ecological and environmental issues
Download or read book Structural Evolution of the San Juan Thrust System Orcas and Shaw Islands WA written by Kevin Quillan and published by . This book was released on 2017 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Juan Thrust System represents the western elements of the Cascades orogen and preserves evidence for Cretaceous Cordilleran margin tectonics. The kinematics of deformation phases and their temporal relationship to accretionary wedge high-pressure low-temperature metamorphism remains uncertain. The structural and metamorphic evolution of the San Juan Thrust System was studied on Orcas and Shaw Islands in Western Washington. Detailed field mapping indicates that a widespread S1 flattening fabric (formed during D1) is subparallel to and cut by an S2 fabric found within brittle-ductile shear zones that bound the terranes (formed during D2). Post-cleavage brittle structures (formed during D3) offset terrane contacts and S2 fabrics and include cm- to m-scale slip on normal, strike-slip, and thrust faults that have mutual crosscutting relationships. Metamorphic investigations utilizing vein mineralogy and fluid inclusion analysis reveal the pressure and temperature relations during each stage of deformation. Maximum temperatures of ~200 ̊C and pressures of ≥5.5 kbar are indicated by both the preservation of aragonite within D1-D3 veins, and by a minor crystal-plastic component of quartz deformation within D2 shear zones. These conditions are interpreted to indicate deformation occurred in an accretionary wedge setting. Using pressure-temperature constraints and kinematics of each event, I suggest a tectonic model that includes (1) D1 terrane accretion and fabric formation somewhere south along the continental margin, (2) NW-directed translation along the margin during oblique subduction as terranes were assembled on top of one another into their current nappe stack along D2 shear zones, and (3) subhorizontal extension and vertical thinning along brittle D3 structures. A predominance of margin-parallel extension in the forearc during D3 may be a response to "unbuttressed" collapse of an overthickened wedge, or from continued oblique subduction in the presence of a curved margin. This model supports previous interpretations of a NW-dominated thrust system, but high-pressure low-temperature constraints indicate that assembly of the nappe stack and later D3 brittle deformation represent continued structural evolution within an accretionary wedge. Results of this study indicate that the structures accountable for exhumation of the San Juan Thrust System and emplacement of terranes above the unmetamorphosed Wrangellia terrane are yet to be discovered.

Download or read book Geology and Landscape Evolution written by Joseph A. DiPietro and published by Elsevier. This book was released on 2018-04-16 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geology and Landscape Evolution: General Principles Applied to the United States, Second Edition, is an accessible text that balances interdisciplinary theory and applications within the physical geography, geology, geomorphology and climatology of the United States. The vast diversity of terrain and landscape across the United States makes this an ideal tool for geoscientists worldwide who research the country’s geological and landscape evolution. The book provides an explanation of how landscape forms, how it evolves and why it looks the way it does. This new edition is fully updated with greater detail throughout and additional figures, maps, drawings and photographs. Rather than limiting the coverage specifically to tectonics or to the origin and evolution of rocks with little regard for the actual landscape beyond general desert, river and glacial features, this book concentrates specifically on the origin of the landscape itself, with specific and exhaustive reference to examples from across the United States. The book begins with a discussion of how rock type and rock structure combine with tectonic activity, climate, isostasy and sea level change to produce landscape and then explores predicting how landscape will evolve. The book goes on to apply those concepts to specific examples throughout the United States, making it a valuable resource for understanding theoretical geological concepts through a practical lens. Presents the complexities of physical geography, geology, geomorphology and climatology of the United States through an interdisciplinary, highly accessible approach Offers hundreds of full-color figures, maps and photographs that capture the systematic interaction of land, rock, rivers, glaciers, global wind patterns and climate, including Google Earth images Provides a thorough assessment of the logic, rationale, and tools required to understand how to interpret landscape and the geological history of the Earth Features exercises that conclude each chapter, aiding in the retention of key concepts Updated with greater detail throughout and additional figures, maps, drawings and photographs Includes additional subheadings so that material is easier to find and digest Includes an all-new chapter on glaciation and expanded exercises using Google Earth images to enhance understanding
