Stratigraphy of the Canadian Rocky Mountains in the Banff area. Let’s take a look at the general geological setting of Canada. In a nutshell, where the central craton of the continent is exposed in northern Saskatchewan, Manitoba, Ontario, Quebec, Nunavut and the Northwest Territories, it is called the Canadian Shield. The Devonian (/ d ɪ ˈ v oʊ n. i. ən, d ə-, d ɛ-/ dih-VOH-nee-ən, də-, deh-) is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied.. The first significant adaptive radiation. Devonian Period - Devonian Period - Devonian geology: The union of the paleocontinents of Laurentia and Baltica occurred near the beginning of the Devonian to form a single landmass that has been referred to both as Laurussia and as Euramerica. The northern portion of the combined landmass gave rise to widespread areas of continental desert, playa, and alluvial plain deposits that form one of.
