AbstractThe NATMAP Program (1991-2003) of the Geological Survey of Canada had a mandate to support field-based bedrock and surficial mapping projects. The Central Foreland NATMAP Project (1997-2002) focused on the bedrock and surficial geology of two contrasting transects across the Cordilleran foothills, one in the northern Rocky Mountain of British Columbia, the other across the Liard Plateau of southeast Yukon and adjacent Northwest Territories. Numerous stratigraphic sections were measured in support of this work. The present Bulletin provides detailed descriptions and photographic documentation of most of the Proterozoic to Devonian sections measured during the Project, as well as a number of sections measured in the project area in the 1960s and 1970s but not previously published in detailed form. This introductory chapter summarizes the Bulletin and points the reader to additional Central Foreland NATMAP Project stratigraphic sections that have been published in other venues.
Summary(Plain Language Summary, not published)
This bulletin presents detailed descriptions and measured thicknesses for a suite of 79 stratigraphic sections ranging in age from the Late Precambrian to the Devonian, distributed across northern British Columbia and adjacent Yukon. These descriptions permit interpretations of regional trends in the distribution of shallow water vs deeper water successions through early Paleozoic time. This extensive data compilation underpins syntheses, presented here and in external publications, of the changes to the form and depth of western Canada's Paleozoic marginal seas and their implications for regional hydrocarbon potential.
