Download or read book Paleopalynology written by Alfred Traverse and published by Springer Science & Business Media. This book was released on 2007-05-21 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
Download or read book Early Palaeozoic Biogeography and Palaeogeography written by D.A.T. Harper and published by Geological Society of London. This book was released on 2014-01-27 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.
Download or read book Miospores and Organic walled Microphytoplankton of Devonian Carboniferous Boundary Beds Bakken Formation Southern Saskatchewan written by Geoffrey Playford and published by . This book was released on 1993 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Core samples obtained from five petroleum exploration wells in southern Saskatchewan provide the material basis for this first detailed palynological study of the subsurface Bakken Formation in the northern part of the intracratonic Williston Basin. The Bakken Formation is a holomarine unit that constitutes part of the organic-rich, predominantly black shale sedimentary sequence that accumulated around latest Devonian-earliest Carboniferous time in the Williston Basin and in the contiguous northern Rocky Mountains region of the Western Canada Basin. The Bakken is a distinctive stratigraphic marker because of its lithological consistency in toto and its three subunits, all of which were sampled for this investigation. The Bakken is economically important as a probable petroleum source (shale members) and because of its reservoir properties (arenaceous member).
Download or read book Devonian Change written by Geological Society of London and published by Geological Society of London. This book was released on 2009 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid evolution of terrestrial ecosystems in the Devonian Period combined with climate change and many global events had a pronounced influence on sedimentation and biodiversity in various terrestrial and marine settings. This volume presents a number of case studies which cover the following topics land-sea transitional settings, the role of ecological-evolutionary subunits, the diversity and palaeoecology of reef building organisms and microfloras with respect to sedimentary processes and global events.
Download or read book Applied Stratigraphy written by Eduardo A.M. Koutsoukos and published by Springer Science & Business Media. This book was released on 2006-08-04 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratigraphy has come to be indispensable to nearly all branches of the earth sciences, assisting such endeavors as charting the course of evolution, understanding ancient ecosystems, and furnishing data pivotal to finding strategic mineral resources. This book focuses on traditional and innovative stratigraphy techniques and how these can be used to reconstruct the geological history of sedimentary basins and in solving manifold geological problems and phenomena.
Download or read book Devonian Climate Sea Level and Evolutionary Events written by R. T. Becker, 1st and published by Geological Society of London. This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.
