Book Synopsis Siliceous Deposits of the Tethys and Pacific Regions by : James R. Hein
Download or read book Siliceous Deposits of the Tethys and Pacific Regions written by James R. Hein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the biological origin of many siliceous deposits, their geochemical transformation in the marine environment, and their occurrence in many formations around the world, oceanographers, paleontologists, geologists, geochemists, and sedimentologists are working closely together to trace the evolution of such deposits. In this book, leading experts from all of these disciplines present new data on fine-grained deposits such as chert, primarily of the Tethys region but also of the Pacific. Much of the information presented here was gathered recently in coordinated international research projects and is made available in English for the first time.

Download or read book Reef Evolution written by Rachel Wood and published by . This book was released on 1999 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: If one does not understand the biology of the coral reef, one does not understand the reef at all. So, using more than 250 illustrations and specially drawn ecological reconstructions of reef communities, Rachel Wood provides a unique evolutionary approach to the understanding of ancient coral reef ecosystems. Marine organisms have aggregated to form reefs for over 3.5 billion years--creating the largest biologically constructed feature on earth, some visible from space. However, their study has been largely descriptive. Reef Evolution, documents the fundamental biological processes and innovations which have molded the evolution of reef ecosystems and given rise to the highly complex communities found today. The appearance of clonality, the acquisition of photosymbiosis, and the radiation of predator groups are all discussed in depth. Data from the fossil record documents the evolutionary development of reef ecosystems. Although reefs only occupy a small percentage of the oceans, their importance to the marine environment is many-faceted and global. They create harbors and allow the development of shallow basins with associated mangrove or seagrass communities; they protect coastlines from erosion; are involved in the regulation of atmospheric carbon, which in turn contributes to climate control. can provide extensive oil and gas reservoirs. From a biological standpoint, however, the great significance of reefs lies in their ability to generate and maintain a substantial proportion of tropical marine biodiversity. This unique interdisciplinary approach provides students and researchers in evolution, marine biology, ecology, paleontology, biodiversity, and geology with a text that will allow them to truly understand the biological innovations which have molded the evolution of coral reefs and given rise to the highly complex communities found today.

Book Synopsis Skarns in British Columbia by : Gerald E. Ray
Download or read book Skarns in British Columbia written by Gerald E. Ray and published by . This book was released on 1997 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.
Book Synopsis Tectonic Growth of a Collisional Continental Margin by : Kenneth D. Ridgway
Download or read book Tectonic Growth of a Collisional Continental Margin written by Kenneth D. Ridgway and published by Geological Society of America. This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The convergent margin of southern Alaska is considered one of the type areas for understanding the growth of continental margins through collisional tectonic processes. Collisional processes that formed this margin were responsible for multiple episodes of sedimentary basin development, subduction complex growth, magmatism, and deformation. Two main collisional episodes shaped this Mesozoic-Cenozoic continental margin. The first event was the Mesozoic collision of the allochthonous Wrangellia composite terrane. This event represents the largest addition of juvenile crust to western North America in the past 100 m.y. The second event is the ongoing collision of the Yakutat terrane along the southeastern margin of Alaska. This Cenozoic event has produced the highest coast mountain range on Earth (Saint Elias Mountains), the Wrangell continental arc, and sedimentary basins throughout southern Alaska. Active collisional processes continue to shape the southern margin of Alaska, mainly through crustal shortening and strike-slip deformation, large-magnitude earthquakes, and rapid uplift and exhumation of mountain belts and high sedimentation rates in adjacent sedimentary basins. This volume contains 24 articles that integrate new geophysical and geologic data, including many field-based studies, to better link the sedimentary, structural, geochemical, and magmatic processes that are important for understanding the development of collisional continental margins."--Publisher's website.
Book Synopsis Upper Paleozoic Stratigraphic History and Provenance of the Farewell Terrane, SW Alaska by : Matthew A. Malkowski
Download or read book Upper Paleozoic Stratigraphic History and Provenance of the Farewell Terrane, SW Alaska written by Matthew A. Malkowski and published by . This book was released on 2010 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Farewell terrane, in southwest Alaska, is predominantly located in the western Alaska Range, but crops out as far north as the Kuskokwim Mountains and represents one of the largest exotic terranes in the North American Cordillera. Exposed both north and south of the Denali fault, the Farewell terrane contains three somewhat distinct stratigraphic successions: 1) Neoproterozoic-Devonian carbonate rocks of the Nixon Fork subterrane, 2) Cambrian-Devonian carbonate and siliciclastic strata of the Dillinger subterrane, and 3) Devonian-Jurassic siliciclastic strata of the Mystic subterrane. This investigation aims to constrain the upper Paleozoic tectonic evolution of the Farewell terrane through sedimentologic interpretations and measured stratigraphy as well as by utilizing combined provenance techniques of sandstone modal compositions and U-Pb detrital zircon geochronology. Measured stratigraphy and sedimentologic analyses of upper Paleozoic (Mississippian--Permian) siliciclastic strata from the Mystic subterrane suggest a submarine basin-floor turbidite fan depositional environment. Modal composition trends reveal pervasive occurrences of lithic volcanic and sedimentary grains reflecting contributions from a magmatic arc to a recycled orogen source. U-Pb detrital zircon age peaks from the newly defined Mystic Pass formation reveals four trends in age spectra: 2000-1800 Ma, 465-405 Ma, 365-315 Ma, and 305-290 Ma. These trends correlate with both Siberian and North American magmatic source areas.
