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.

Download or read book Paleobiology of the Polycystine Radiolaria written by David Lazarus and published by John Wiley & Sons. This book was released on 2020-12-29 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.

Download or read book Caribbean Basins written by P. Mann and published by Elsevier. This book was released on 1999-12-15 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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.

Download or read book Introduction to Microfossil Biostratigraphy written by M. Dan Georgescu and published by Cambridge Scholars Publishing. This book was released on 2021-09-24 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook will appeal to students and graduates making their first steps in the application of both microfossils and stratigraphy. It presents, in detail, the historical development of microfossil biostratigraphy, from its birth to the emergence of sequence stratigraphy, including its roots in classical biostratigraphy. The interplay between the academic and economical challenges, on one hand, and developments in microfossil biostratigraphy, on the other, is explored thoroughly. The book also presents an introduction to the scientific concepts used in microfossil biostratigraphy practice, and the uses in microbiostratigraphy of 25 groups of microfossils, such as algae, protistans, reproductive plant debris, invertebrates, chordates and vertebrates, and microproblematica groups. It also provides a numerical method to calculate the biostratigraphical resolution of these microfossil groups.
