Devonian strata of the Western Canada Sedimentary Basin (WCSB) occur in a widespread belt extending from the Arctic Ocean and the Alaska-Yukon border on the north to the southeast through the Northwest Territories, northeast British Columbia, and Alberta into Saskatchewan and southwest Manitoba (Figure 1). This short course manual discusses the temporal and spatial evolution of Devonian carbonates and associated deposits in the WCSB, along with a discussion of early Mississippian strata. The initial 10 chapters of this manual, including this introductory chapter, consider the evolution of Devonian deposits; the 11th chapter deals with the latest Devonian-earliest Mississippian sequence. The 12th and final chapter provides a summary of the entire course.
The Devonian of the WCSB is, of course, best known for the occurrence of reefs. These reefs occur in multiple phases of sedimentation and vary according to depositional setting, evolution, related facies associations, areal extent, thickness, fauna and morphology. Many of these reefs are limited in distribution to the subsurface; others are magnificently exposed in the Rocky Mountains. A summary of all of these reefs is provided by Moore (1988a).

Devonian-Early Mississippian Carbonates of the Western Canada Sedimentary Basin: A Sequence Stratigraphic Framework
The Devonian and early Mississippian strata in the Western Canada Sedimentary Basin include a wide diversity of shallow-water carbonate and basin filling carbonate, shale and evaporite facies. Of these, the large Devonian platform-reef complexes are the most spectacular. They occur in magnificent exposures in the Front Ranges of the Canadian Rockies and in the subsurface of Alberta. In the subsurface, these complexes pool many of the largest oil and gas accumulations in Western Canada. This short course is intended to provide a summary of Devonian and early Mississippian deposits in the subsurface of the Western Canada Sedimentary Basin. One of the major goals is to present the evolution of these strata in a sequence-stratigraphic context. The role of sea-level, tectonic and depositional controls on “stacking” and facies patterns are considered. A second major goal is to relate the occurrence of hydrocarbon pools to this sequence-stratigraphic framework.
