Devonian Period
Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the early Devonian Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.
Devonian rocks are found globally, reflecting the distribution of ancient landmasses and marine environments during that period. Their occurrence is categorized by both terrestrial and marine deposits:1
North America
Devonian rocks are widespread across the continent. Notable locations include:
* Eastern North America: Famous sequences in New York and the Appalachian region, including the Catskill Delta.23
* Mid-continent and West: Rocks are found in the Great Lakes region, New Mexico, Utah, Nevada, and Montana.2
* Canada: Extensive deposits exist in the subsurface of Saskatchewan, oil-bearing reefs in Alberta, and throughout the Canadian Rockies, the Arctic islands, and Alaska.2
Europe and Russia
- Western Europe: Significant marine and terrestrial deposits occur in England (notably Devon), Wales, Scotland, France, Belgium, and Germany.45
- Eastern Europe and Russia: Deposits are found in Poland, the Ural Mountains, the Russian Platform, Novaya Zemlya, and near St. Petersburg.35
Other Regions
- Africa: Notable fossil-rich deposits are found in Morocco and Algeria.15
- Australia: Significant carbonate reef deposits occur in Western Australia, with fold belts present in the east from Queensland to Tasmania.13
- South America: Rocks are found in Brazil and along the Andes mountain range.13
