Available in PDF, EPUB and Kindle. Book excerpt: The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

Download or read book Biochronological Correlations written by Jean Guex and published by Springer. This book was released on 1991-10-28 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this book is to explain how to create a synthesis of complex biostratigraphic data, and how to extract from such a syn thesis a relative time scale based exclusively on the fossil content of sedimentary rocks. Such a time scale can be used to attribute relative ages to isolated fossil-bearing samples. From a practical point of view, the method described in this book will particularly interest paleontologists and geologists who must construct zonations and establish correlations on the basis of bio stratigraphic data that are both plentiful and apparently contra dictory. It is well known that the difficulties involved in constructing bio chronologic scales are largely due to the discontinuous nature of the fossil record. We know that the relationships between the first ap pearances (or disappearances) of different fossil species are rarely constant in stratigraphic sections that are distant from each other. It if often extremely difficult to discover datums or sets of species that are useful in making significant biochronologic correlations on a large scale. The theoretical model explained here (known as the Unitary As sociation Method) provides clear solutions to most of these problems. That method is purely deterministic, as opposed to statistical and probabilistic analytical techniques producing "average" ranges. We demonstrate in Chapter 15 why most of these techniques produce results which are usually not compatible with the original biostrati graphic observations (i.e., the taxonomic contents of the studied sam ples are not reproduced in the outputs).

Carter and published by Geological Survey of Canada. This book was released on 1988 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive geological investigation of Mesozoic strata of the Pacific Rim is currently underway to determine the hydrocarbon potential of these rocks. Precise biostratigraphic control is essential for advances and substantial new information on the Jurassic biostratigraphy and taxonomy of Jurassic radiolarians from the Queen Charlotte Islands is presented in this report. Five new genera and 42 new species are described, most of which have restricted, and therefore useful, biostratigraphic ranges. A preliminary radiolarian zonation is proposed, calibrated with associated ammonite and foraminiferal faunas.

This book was released on 1989-05-25 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume 2 describes siliceous and other non-calcareous microfossils, covering radiolaria, diatoms, silicoflagellates, dinoflagellates and ichthyoliths.

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 Paleobiology of the Polycystine Radiolaria written by David Lazarus and published by John Wiley & Sons. This book was released on 2020-12-21 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycystine radiolaria are exclusively marine protists and are found in all ocean waters, from polar regions to the tropics, and at all water depths. There are approximately 600 distinct described living species and several thousand fossil species of polycystines. Radiolarians in general, and polycystines in particular, have recently been shown to be a major component of the living plankton and important to the oceanic carbon cycle. As fossils radiolarians are also fairly common, and often occur in sediments where other types of fossils are absent. This has made them very valuable for certain types of geologic research, particularly estimating the geologic age of the sediments containing them, and as guides to past oceanic water conditions. As our current understanding of the biology, and even taxonomy of the living fauna is still very incomplete, evolutionary studies based on living polycystines are still rare. However, the common occurrence of numerous specimens for many species, and in a wide variety of oceanic environments, provides an excellent opportunity to study the processes of biologic evolution in the fossil record. Paleobiology of the Polycystine Radiolaria is the first major book on radiolarians to appear in the western literature since 2001. Focusing on living and fossil siliceous shelled radiolarians, it is notable for its emphasis not upon morphologic or taxonomic detail but on concepts and applications. The book attempts to provide a balanced, critical review of what is known of the biology, ecology, and fossil record of the group, as well as their use in evolutionary, biostratigraphic and paleoceanographic research. Full chapters on the history of study, and molecular biology, are the first ever in book form. Written for an audience of advanced undergraduate to doctoral students, as well as for a broad range of professionals in the biological and Earth sciences, Paleobiology of the Polycystine Radiolaria summarizes current understanding of the marine planktonic protist group polycystine radiolaria, both in living and fossil form.
