Available in PDF, EPUB and Kindle. Book excerpt: Scientific proof validating the legends and myths of ancient floods, fires, and weather extremes • Presents scientific evidence revealing the cause of the end of the last ice age and the cycles of geological events and species extinctions that followed • Connects physical data to the dramatic earth changes recounted in oral traditions around the world • Describes the impending danger from a continuing cycle of catastrophes and extinctions There are a number of puzzling mysteries in the history of Earth that have yet to be satisfactorily explained by mainstream science: the extinction of the dinosaurs, the vanishing of ancient Indian tribes, the formation of the mysterious Carolina Bays, the disappearance of the mammoths, the sudden ending of the last Ice Age, and the cause of huge underwater landslides that sent massive tsunamis racing across the oceans millennia ago. Eyewitness accounts of these events are chronicled in rich oral traditions handed down through generations of native peoples. The authors’ recent scientific discoveries link all these events to a single cause. In The Cycle of Cosmic Catastrophes Richard Firestone, Allen West, and Simon Warwick-Smith present scientific evidence about a series of prehistoric cosmic events that explains why the last Ice Age ended so abruptly. Their findings validate the ubiquitous legends and myths of floods, fires, and weather extremes passed down by our ancestors and show how these legendary events relate to each other. Their findings also support the idea that we are entering a thousand-year cycle of increasing danger and possibly a new cycle of extinctions.

Download or read book Vanadium Isotopes written by Sune G. Nielsen and published by Cambridge University Press. This book was released on 2021-01-28 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vanadium isotope ratios (51V/50V) have potential to provide information about changes in past ocean oxygen contents. In particular, V isotopes may find utility in tracing variations at non-zero oxygen concentrations because the redox couple that controls V elemental and isotopic abundances in seawater (vanadate-vanadyl) appears to operate around 10M O2. This characteristic sets V isotopes apart from many other metal isotope redox proxies that require more reducing conditions to register significant changes in their isotope budgets. The oxygen abundance sensitivity range of V isotopes suggests that this paleoproxy could be particularly useful in tracing marine oxygenation changes throughout the Phanerozoic and potentially beyond.

Download or read book The Deposition of Organic carbon rich Sediments written by Nicholas Bennett Harris and published by SEPM Soc for Sed Geology. This book was released on 2005 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depositional models for organic-carbon-rich sediments have been the subjects of both great interest and great controversy for many years. These sediments serve as the ultimate source of virtually all oil and gas. They also represent the interface between biological and geological processes and provide critical evidence for the state of the atmosphere and oceans. Yet despite their importance and decades of research, the origin of these sediments remains the source of vigorous disagreement. The twelve papers in this volume represent the cutting edge of research in this topic. They explore the origin of organic-carbon-rich sediments through a variety of techniques, including sedimentology, geochemistry, paleontology and computer modeling. All papers take multidisciplinary approaches to the topic, and together, they demonstrate the complex interconnected processes that trigger the deposition of organic carbon. This book will appeal to geoscientists in many disciplines, including explorers for petroleum who need models for source rock deposition, organic and inorganic geochemists who study processes in water and sediment, sedimentologists who interpret ancient deposition environments, and climatologists and oceanographers who reconstruct the behavior of the ancient atmosphere and oceans.

Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!

Download or read book The Pyrite Trace Element Paleo Ocean Chemistry Proxy written by Daniel D. Gregory and published by Cambridge University Press. This book was released on 2020-12-24 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the trace element content of sedimentary pyrite as a proxy for the trace element composition of past oceans has recently emerged. The pyrite proxy has several potential advantages over bulk sample analysis: preservation through metamorphism; little dilution during analysis (samples are ablated not dissolved, allowing for the less abundant elements commonly held in the sulfide fraction to be investigated as proxies); accurate measurement of several elements simultaneously; the ability to screen sediments for hydrothermal overprint; and the technique can give information regarding trace element availably at multiple stages of diagenesis. Because of these multiple strengths, the pyrite trace element proxy is a valuable potential addition to the paleo-ocean chemistry tool kit.

Download or read book Urumaco and Venezuelan Paleontology written by Marcelo R. Sánchez-Villagra and published by Indiana University Press. This book was released on 2010-07-16 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urumaco and Venezuelan Paleontology offers a synthesis of the paleontological record of Venezuela, including new discoveries on stratigraphy, paleobotany, fossil invertebrates, and vertebrates. Besides providing a critical summary of the record of decapods, fishes, crocodiles, turtles, rodents, armadillos, and ungulates, several chapters introduce new information on the distribution and paleobiology of groups not previously studied in this part of the world. Given its position in the northern neotropics, close to the Panamanian land bridge, Venezuela is a key location for understanding faunal exchanges between the Americas in the recent geological past. The book reviews the recent paleobotanical and vertebrate fossil record of the region, provides an understanding of Pleistocene climatic change and biogeography for the last few thousand years, and integrates new information with summaries of Spanish language works on Venezuelan geology and paleontology.
