Encyclopedia of Geology, Second Edition presents in six volumes state-of-the-art reviews on the various aspects of geologic research, all of which have moved on considerably since the writing of the first edition. New areas of discussion include extinctions, origins of life, plate tectonics and its influence on faunal provinces, new types of mineral and hydrocarbon deposits, new methods of dating rocks, and geological processes. Users will find this to be a fundamental resource for teachers and students of geology, as well as researchers and non-geology professionals seeking up-to-date reviews of geologic research. Provides a comprehensive and accessible one-stop shop for information on the subject of geology, explaining methodologies and technical jargon used in the field Highlights connections between geology and other physical and biological sciences, tackling research problems that span multiple fields Fills a critical gap of information in a field that has seen significant progress in past years Presents an ideal reference for a wide range of scientists in earth and environmental areas of study
"Field instruction has traditionally been at the core of the geoscience curriculum. The field experience has been integral to the professional development of future geoscientists, and is particularly important as it applies to student understanding of spatial, temporal, and complex relations in the Earth system. As important as field experiences have been to geosciences education and the training of geoscientists, the current situation calls for discipline-wide reflection of the role of field experiences in the geoscience curriculum in light of practical and logistical challenges, evolution in employment opportunities for geoscientists, and changing emphases in the geoscience curriculum. This volume seeks to broaden participation in field instruction by showcasing diverse approaches to teaching in the field across the many geo-disciplines encompassed by GSA."--books.google.
The timing of Acadian orogenesis in Maine is reassessed, on the basis of a new Silurian-Devonian time scale, new U/Pb and 40Ar/39Ar ages of Acadian plutons, new conodont and palynomorph ages of strata that constrain the age of deformation, and published information. This analysis shows that the Acadian deformation front migrated some 240 km (present distance) from southeast to northwest during a span of about 40 million years from Late Silurian to Middle Devonian time.
Many faults appears to form persistent zones of weakness that fundamentally influence the distribution, arichitecture and movement patterns of crustal-scale deformation and associated processes in both continental and oceanic regions. They act as conduits for the focused migration of economically important fluids and also constitute one of the most important global geological hazards. This book brings together papers by an international group of Earth Scientists to discuss a broad range of topics centred upon the controls of fault weakening and the role of such faults during lithosphere deformation.
This 10-chapter volume encompasses contributions from a wide spectrum of Earth science disciplines, including geophysics, geodynamics, geochemistry, and petrology, to provide an overview of the nature and evolution of the crust-mantle and lithosphere-asthenosphere boundaries in different tectonic settings, combining studies that exploit different types of data and interpretative approaches. The integration of geochemical, geophysical, and geodynamic data sets and their interpretation provides a state-of-the-art summary of current understanding, and will serve as a blueprint for future research activities.
This special volume stems from a symposium 'Granitic Systems - State of the Art and Future Avenues' that was held at the Department of Geology, University of Helsinki to mark the retirement of Professor Ilmari Haapala. The twenty articles in the volume cover a wide range of granite-related topics and focus on three general themes: tectonics and source regions, petrologic processes, and fractionated granites and pegmatites. Both original papers and reviews are included, and the volume will be acknowledged by anyone with a background in Earth Sciences ad a flavor for granitoid rocks. * Comprehensive account of the current status of granite-oriented research * Topics ranging from mineralogy, petrology, and geochemistry to tectonics and crustal evolution
Landscape Evolution in the United States is an accessible text that balances interdisciplinary theory and application within the physical geography, geology, geomorphology, and climatology of the United States. Landscape evolution refers to the changing terrain of any given area of the Earth's crust over time. Common causes of evolution (or geomorphology—land morphing into a different size or shape over time) are glacial erosion and deposition, volcanism, earthquakes, tsunamis, tornadoes, sediment transport into rivers, landslides, climate change, and other surface processes. The book is divided into three main parts covering landscape components and how they are affected by climactic, tectonic and ocean systems; varying structural provinces including the Cascadia Volcanic Arc and California Transpressional System; and the formation and collapse of mountain systems. The vast diversity of terrain and landscapes across the United States makes this an ideal tool for geoscientists worldwide who are researching the country's geological evolution over the past several billion years. - Presents the complexities of physical geography, geology, geomorphology, and climatology of the United States through an interdisciplinary, highly accessible approach - Offers more than 250 full-color figures, maps and photographs that capture the systematic interaction of land, rock, rivers, glaciers, global wind patterns and climate - 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
