Devon Island Formation
Geologic formation in Nunavut, Canada
From Wikipedia, the free encyclopedia
The Devon Island Formation is a geologic formation in the Canadian Arctic.[1] It preserves fossils dating back to the late Silurian and Devonian periods.[2]
The formation was originally named by Raymond Thorsteinsson for a sequence of calcareous, graptolitic mudrocks on northern Devon Island situated between the Douro Formation below and the Sutherland River Formation above.[1] The latter formation is now considered synonymous with the Goose Fiord Formation.[2] The Devon Island Formation extends from the west coast of Devon Island through the Grinnell Peninsula, and well across the southern part of Ellesmere Island.[2]
