View: 7743The Survey makes accessible the core knowledge of the sciences to curious readers with no special preparation. Within the 377 articles here, 141 cover the major subfields of physical geology, 26 treat areas of economic geology, from essential minerals and other earth resources to the variety of ways man harnesses geothermal, wind, ocean, solar, and nuclear power. Thirty articles examine a range of issues in geochemistry. Geophysics is given full coverage in 35 articles. The planet's history, as well as its impact on the development of life and various early life forms, is explored in 22 articles on fossils, ice ages, dinosaurs, mass extinctions, and evolution. Water is examined in all its forms and sources in 27 articles. There are 36 articles on the solar system, eight on major mountain ranges, soils are done in eight, the atmosphere in 18. Averaging seven pages, articles begin with ready-reference matter and a list of principal terms. A summary section forms the major part of each article, providing a description of either the phenomenon or the methodology. "Context," the concluding section of each essay, presents the conclusions, applications, and implications derived from investigation of the topic. Finally, an annotated, selected bibliography directs the reader to sources that are accessible to the nonspecialist. Cross-references lists articles that offer additional information on the same or a related topic.

View: 1778This 21-chapter volume provides a regionally-comprehensive collection of original studies of Caribbean basins conducted by academic and petroleum geologists and geophysicists in the early and mid-1990s. The common tectonic events discussed in the volume including the rifting and passive margin history of North and South America that led to the formation of the Caribbean region; the entry of an exotic, Pacific-derived Great Arc of the Caribbean at the leading edge of the Caribbean oceanic plateau; the terminal collision of the arc and plateau with the passive margins fringing North and South America; and subsequent strike-slip and accretionary tectonics that affected the arc-continent collision zone. Two introductory chapters (Part A) utilize recent advances in quantitative plate tectonic modeling and satellite-based gravity measurements to place the main phases of Caribbean basin formation into a global plate tectonic framework. Nineteen subsequent chapters are organized geographically and focus on individual or groups of genetically-linked basins. Part B consists of five chapters which mainly focus on basins overlying the North America plate in the Gulf of Mexico, Cuba and the Bahamas that record its rifting from South America in late Jurassic to Cretaceous time. Part C has six chapters that focus on smaller, usually heavily faulted and onshore Cenozoic basins of the northern Caribbean that formed in response to arc collisional and strike-slip activity along the evolving North America-Caribbean plate boundary. The two chapters in Part D focus on Cenozoic basins related to the Lesser Antilles arc system of the eastern Caribbean. Part E is comprised of three chapters on the Jurassic-Recent sedimentary basins of the eastern Venezuela and Trinidad area of the southeastern Caribbean. These basins reflect both the Jurassic-Cretaceous rifting and passive margin history of separation between the North and South America plates as well as a much younger phase of Oligocene to recent transpression between the eastward migrating Lesser Antilles arc and accretionary wedge and the South America continent. The three chapters of Part F contain deep penetration seismic reflection and other geophysical data on the largely submarine Cretaceous Caribbean oceanic plateau that forms the nucleus of the present-day Caribbean plate.

View: 7346Active Tectonics is a carefully organized, easily understandable book. Extremely current throughout, this book thoroughly explores the effects of earthquakes and active tectonic systems on humans, geomorphic systems, and Earth's topography. Complete with numerous case studies in a variety of regions, the very latest advances in the field, separate quantitative techniques boxed sections, and a host of pedagogical aids. This comprehensive book focuses on new advances in the technology and new applications to geology and tectonics. Increased material on Quaternary chronology, including lichen chronology and micro stratigraphy of desert varnish. New studies, including research in the Olympic Mountains, Nepal, Australia, Taiwan, the Himalaya, and the New Madrid seismic zone of the central United States. New techniques such as cosmogenic surface-exposure dating, argon and helium geobarometry and geothermometry, regional hyposometric analysis using digital elevation models, geodetic positioning, and coupled geodynamical computer simulations of topographic evolution are covered. Covers a number of regions with case studies including: Alaska; Pacific Northwest; California; The basin and range; Midwest; and East Coast. Ideal for beginning readers in active tectonics, geomorphology and natural hazards. This book may also be of interest to city planners, seismic engineers, and other non-geologists.
