Book Mesozoic and Cenozoic Sequence Stratigraphy of European Basins

Download or read book Mesozoic and Cenozoic Sequence Stratigraphy of European Basins written by Pierre Charles de Graciansky and published by . This book was released on 1998 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was designed to build a documented chronostratigraphic and outcrop record of depositional sequences calibrated across European basins. Data on standard stages, magnetostratigraphy, and geochronology integrated with high resolution biostratigraphy calibrate the stratigraphic position of depositional sequence boundaries. Higher order eustatic sequences show a significant increase in the number identified. A good portion of the European Mesozoic and Cenozoic succession is set in the sequence stratigraphic context with a stratigraphic record of its bonding surfaces.

Book Global Changes in Paleoproductivity Biological Export and Deep Water Oxygenation Across the Eocene Oligocene Transition

Download or read book Global Changes in Paleoproductivity Biological Export and Deep Water Oxygenation Across the Eocene Oligocene Transition written by Genevieve Elsworth and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Eocene-Oligocene transition (EOT) (~33.7 Ma) delineates the most abrupt shift from "greenhouse" to "icehouse" climates during the Cenozoic. At this time, substantial global cooling and the emplacement of the Antarctic ice sheet accompanied perturbations to the carbon cycle. Profound climatic reorganization across the EOT is often attributed to a decline in atmospheric pCO2; however, the mechanism behind this decrease is poorly understood. Considering the importance of atmospheric pCO2 drawdown for the emplacement of the Antarctic ice sheet, a more complete understanding of the controlling processes are required. The present study presents new and existing data compiled from globally distributed Ocean Drilling Program (ODP) Sites 689 (Maud Rise, Atlantic Sector of Southern Ocean), 744 (Kerguelen Plateau, Indian Sector of Southern Ocean), 925 (Ceara Rise, Western Equatorial Atlantic Ocean), 1090 (Agulhas Ridge, Southeastern Atlantic Ocean), and 1218 (Eastern Equatorial Pacific Ocean). A multi-proxy approach is applied to provide indications of silica availability (biogenic opal MAR), calcium carbonate compensation depth (carbonate MAR), biological surface export (BaEX MAR), and deep water oxygenation (MnEF and UEF). Trends in biogenic opal and carbonate deposition across the EOT suggest the weathering of both silicates and carbonates to exert control on ocean biogeochemistry on geologic timescales. A pulse of biogenic opal deposition is consistent with accelerated silicate weathering both in Antarctica and globally, while enhanced weathering of exposed carbonate shelves accompanied a deepening of the calcium carbonate compensation depth (CCD) across the EOT. The enhanced weathering of silicates and carbonates has implications for the drawdown of atmospheric pCO2 across the transition and emphasize the important role played by coupled Earth system feedbacks on climatic and oceanic reorganizations from the late Eocene to the early Oligocene." --

Book Eocene Oligocene Climatic and Biotic Evolution

Download or read book Eocene Oligocene Climatic and Biotic Evolution written by Donald R. Prothero and published by Princeton University Press. This book was released on 2014-07-14 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition from the Eocene to the Oligocene epochs was the most significant event in earth history since the extinction of dinosaurs. As the first Antarctic ice sheets appeared, major extinctions and faunal turnovers took place on the land and in the sea, eliminating forms adapted to a tropical world and replacing them with the ancestors of most of our modern animal and plant life. Through a detailed study of climatic conditions and of organisms buried in Eocene-Oligocene sediments, this volume shows that the separation of Antarctica from Australia was a critical factor in changing oceanic circulation and ultimately world climate. In this book forty-eight leading scientists examine the full range of Eocene and Oligocene phenomena. Their articles cover nearly every major group of organisms in the ocean and on land and include evidence from paleontology, stable isotopes, sedimentology, seismology, and computer climatic modeling. The volume concludes with an update of the geochronologic framework of the late Paleogene. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
