Stratigraphic nomenclature is revised for Middle Ordovician, Upper Ordovician, and Silurian rocks of the southern Rocky Mountains of Canada. Lower Ordovician stratigraphy is briefly reviewed.

Upper Ordovician and Silurian carbonate shelf stratigraphy, facies, and evolution, eastern North Greenland (Bulletin / GrÃ. Fossils of graptolites—small, colonial, planktonic animals—are abundant in these dark Silurian shales. Graptolites were colonial Silurian Period - Silurian Period - Correlation of Silurian strata: The most-challenging goal in stratigraphy is to identify on a global basis all those rocks formed during the shortest possible interval of geologic time.

Francis Xavier University, Antigonish, Nova Scotia B2G 2W5, CanadaFile Size: 2MB. Silurian: Stratigraphy The Silurian lasted from about to million years ago. Its stratigraphy is subdivided into four epochs (from oldest to youngest): the Llandovery, the Wenlock, the Ludlow, and the Pridoli.
Each epoch is distinguished from the others by the appearance of new species of graptolites. Indoor sessions will be held in the Taohualing Hotel, Yichang City, Hubei Province, China.
The mid-conference field trip will visit the Furongian to Middle Ordovician successions, the GSSPs of Dapingian and Hirnantian stages near the Yichang city, and a few historical and scenery sites of Yangtze Gorges.

A detailed lithostratigraphic and biostratigraphic study of the Ordovician‐Silurian boundary section at Råssnäsudden near Motala has resulted in the recognition of two new lithostratigraphic units, the Motala Formation and the Loka Formation. The former is a slightly more than 5 m thick unit of nodular limestone and calcareous mudstone of Cited by: COVID Resources.

Aspy terrane units are most similar to Ordovician–Silurian volcanic and metamorphic units in southwestern Newfoundland, including the La Poile Group and the Port aux Basques gneiss. Together with other occurrences of Late Ordovician to Early Silurian volcanic-arc units, they indicate that subduction-related compressional tectonics continued into the Silurian in parts of the northern Appalachian by: Palaeogeography, Palaeoclimatology, Palaeoecology, 51 (): Elsevier Science Publishers B.V., Amsterdam -- Printed in The Netherlands THE LATE ORDOVICIAN--EARLY SILURIAN GLACIAL PERIOD M.
