AbstractThe Devonian succession of the Northern Canadian Mainland Sedimentary Basin is considerably thicker, and exhibits greater lithofacies variability, than its counterpart across the Western Canada Sedimentary Basin south of 60º. In the Northern Canadian Mainland Sedimentary Basin, Devonian strata are comprised of three complete second order transgressive-regressive cycles of deposition including the depositional sequences of T-R Cycles A, B, and C, and the lower transgressive sequence tract portion of a fourth second order sequence, T-R Cycle D. The carbonate-dominated Lower Devonian succession, including T-R Cycle A and part of Cycle B, is widespread, and has a thickness of up to 3000 metres locally, in contrast to the much thinner and more discontinuous Lower Devonian of the Western Canadian Sedimentary Basin south of 60º. Middle and Upper Devonian strata in the Northern Canadian Sedimentary Basin, like those of the Western Canada Sedimentary Basin, are widespread, but are dominantly siliciclastic. These strata include the upper part of T-R Cycle B, T-R Cycle C, and the lower part of T-R Cycle D. The profound change in sedimentary character from dominantly carbonate, to siliciclastic deposition, from early to late Devonian time reflects an overall evolution in tectonic regime from passive margin rifting to one of active orogenesis.
Summary(Plain Language Summary, not published)
This report describes The Devonian succession of the Northern Canadian Mainland Sedimentary Basin and compares it with that of the Western Canada Sedimentary Basin south of 60º. In the Northern Canadian Mainland Sedimentary Basin, Devonian strata are comprised of three complete cycles of deposition including the depositional sequences and part of a fourth depositional cycle. The carbonate-dominated lower part of the northern Devonian succession is widespread,and has a thickness of up to 3000 metres locally, in contrast to the much thinner and more discontinuous Lower Devonian of the Western Canadian Sedimentary Basin south of 60º. Middle and Upper Devonian strata in the Northern Canadian Sedimentary Basin, like those of the Western Canada Sedimentary Basin, are widespread, but are dominantly siliciclastic. The profound change in sedimentary character from dominantly carbonate, to siliciclastic deposition, from early to late Devonian time reflects an overall evolution in tectonic regime from passive margin rifting to one of active orogenesis.
