Download or read book Silurian and Devonian Spore Zones of the Old Red Sandstone Continent and Adjacent Regions written by John Brian Richardson and published by . This book was released on 1986 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Spores are widespread in marine and nonmarine rocks of Silurian and Devonian age. However, to date no comprehensive spore zonation for the whole of the Silurian and Devonian systems has been proposed. This report describes such a zonation for North America and Europe. New spore zones are calibrated with zones exclusively in marine strata. Thus, a basis for direct time correlation of widespread marine and continental rocks of the Silurian and Devonian of Canada is established in this report. It also provides data that may be useful for the international definition of geological boundaries." --

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 Stratigraphic Analysis of Layered Deposits written by Ömer Elitok and published by BoD – Books on Demand. This book was released on 2012-04-27 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stratigraphy, a branch of geology, is the science of describing the vertical and lateral relationships of different rock formations formed through time to understand the earth history. These relationships may be based on lithologic properties (named lithostratigraphy), fossil content (labeled biostratigraphy), magnetic properties (called magnetostratigraphy), chemical features (named chemostratigraphy), reflection seismology (named seismic stratigraphy), age relations (called chronostratigraphy). Also, it refers to archaeological deposits called archaeological stratigraphy. Stratigraphy is built on the concept "the present is the key to the past" which was first outlined by James Hutton in the late 1700s and developed by Charles Lyell in the early 1800s. This book focuses particularly on application of geophysical methods in stratigraphic investigations and stratigraphic analysis of layered basin deposits from different geologic settings and present continental areas extending from Mexico region (north America) through Alpine belt including Italy, Greece, Iraq to Russia (northern Asia).

Download or read book Migration of the Acadian Orogen and Foreland Basin Across the Northern Appalachians of Maine and Adjacent Areas written by Dwight Culver Bradley and published by . This book was released on 2000 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The timing of Acadian orogenesis in Maine is reassessed, on the basis of a new Silurian-Devonian time scale, new U/Pb and 40Ar/39Ar ages of Acadian plutons, new conodont and palynomorph ages of strata that constrain the age of deformation, and published information. This analysis shows that the Acadian deformation front migrated some 240 km (present distance) from southeast to northwest during a span of about 40 million years from Late Silurian to Middle Devonian time.
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.

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 The Geology of Scotland 4th edition written by N. H. Trewin and published by Geological Society of London. This book was released on 2003-02-24 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 4th edition of The Geology of Scotland is greatly expanded from the previous edition with 34 authors contributing to 20 chapters. A new format has been adopted to provide a different perspective on the geology of Scotland. A brief introduction is followed by a chapter outlining some of the important historical aspects that in the 19th century placed Scottish geologists in the forefront of a new science. Scotland is constructed from a number of terranes that finally combined in roughly their present positions prior to about 410 million years ago. Thus the geology of each terrane is described up the time of amalgamation, providing chapters on the Southern Uplands, Midland Valley, Highlands, Grampian and Hebridean terranes. At the end of this section, a brief synthesis summarizes the events that resulted in the amalgamation of the various terranes into the present configuration. Traditional practice is followed in the description of the Old Red Sandstone, Carboniferous, Permo-Trias, Jurassic, Cretaceous, tertiary and Quaternary strata. A separate chapter covers Tertiary igneous rocks. An attempt is made to tell the story of the geological evolution of Scotland, rather than catalogue all areas and formations. Priority is given to the onshore geology, encouraging the reader to go into the field and visit some of the world-class geology on show in Scotland. The chapters are broadly-based, attempting to integrate the sedimentary and igneous histories, and summarize changes in palaeogeography and palaeoenvironments. Economic aspects are covered with chapters on Metalliferous Minerals, Bulk Resources, Coal and Hydrocarbons. A new departure is the chapter on aspects of Environmental Geology and sustainability. Additionally, this publication contains a colour section of 32 plates, illustrating aspects of Scottish Geology, as well as a coloured geological map of Scotland.
