Pages : 372
Book Description
Darriwilian to Sandbian (Ordovician) Graptolites from Northwest China analyzes the significance of these exquisite, mostly pyritic, graptolites of the middle to late Ordovician period from North China and Tarim, China—locations that have developed the world's most complete successions of strata and fossil records. The book provides the first systematic account of the renowned graptolite faunas, with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, also presenting a comprehensive accounting of the graptolites during the critical transition from the middle to late Ordovician period with important data on new morphologies, the latest conventions in classification, diversity change and evolution, refined biostratigraphy divisions, and correlation with other major regions or continents. The book provides a key resource for paleontologists, stratigraphic specialists, petroleum geologists, and graduate students in varying fields of geology. - Presents the first systematic accounting of these world-renowned graptolite fauna - Provides an ideal reference for those interested in rocks, fossils, and biostratigraphy - Presents over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone - Includes research from the top, most influential, Ordovician graptolite and conodont paleontologists in the world - Generously illustrated with four-color figures and photos throughout

Book Description
&Quot;This Report is revised and expanded from the 1972 publication, providing an up-to-the-minute account of the British Ordovician formations and their correlation nationally and internationally. It also includes the most comprehensive treatment of Ireland ever attempted. The reference list is a comprehensive bibliography of papers on the subject published since 1970.". "This Special Report will be a valuable reference for research and applied geoscientists working with rocks of Ordovician age. It will be of particular interest to those working in, or visiting, the Welsh mountains and the English Lake District."--BOOK JACKET.
A Global Synthesis of the Ordovician System: Part 1
Author: D.A.T. HarperPublisher: Geological Society of London Special Publications
ISBN: 1786205882
Category : Science
Languages : en
Pages : 514
Book Description
The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.
