The Les Méchins region in Quebec provides a unique opportunity to understand the Darriwilian graptolite succession in eastern North America. The graptolite faunas of the upper member of the Anse au Crapaud Formation include the Arienigraptus gracilis, Oncograptus upsilon, Undulograptus austrodentatus, and Holmograptus spinosus biozone faunas and, thus, complement the well known Darriwilian Cited by: In this chapter, starting with a brief review of the research history and current status in the studies of the Ordovician chronostratigraphy in China, the subdivision of the Ordovician System, definition and recognition of its series and stage boundaries, and possible stratigraphic gaps are discussed in details in order to establish a multidisciplinary stratigraphic correlation through an Cited by: 8.
Carbon isotope studies (Kaljo et al. , , ; Kaljo & Martma ; Ainsaar et al. ) of the Ordovician and Silurian carbonate rocks show a good correlation of positive [delta][sup]C excursions with lows of the global sea-level curve and support the primary role of climatic or climatically triggered oceanic processes in the. Global (eustatic) transgressions in Middle & Late Cambrian: In western Laurentia, huge onlap sequences (the Tonto Group exposed from California to the Grand Canyon) Across much of world, very large carbonate banks form Paleogeography and Geology of the Ordovician: Gondwana moves poleward During Late Ordovician, major (but brief) ice age.

The global distribution, setting, and dynamic implications of Ordovician orogenesis are reviewed. Evidence for true Ordovician continent-continent collision is absent. Orogenesis is principally due to accretion of arc terranes and/or ribbon microcontinents.

To encourage, promote, and support research on all aspects of. Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective.
Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over. To encourage, promote, and support research on all aspects of Ordovician geology worldwide and to provide outlets, Ordovician News, international meetings, and a web page, for promoting discussions and reporting results of this research.
Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume Field Trip T of the 28th International Geological Congress will give participants a regional overview of the geology of the Basin and Range province and an introduction to Cambrian and Early Ordovician stratigraphy and paleontology.
