Carboniferous Stoddart Group mixed siliciclastic and carbonate rocks were deposited in a tectonically active extensional setting within the Peace River Embayment, Western Canada Sedimentary Basin (WCSB). Timing and style of the tectonostratigraphic evolution of Stoddart Group depositional basin is in agreement with recently studied late Paleozoic sedimentary deposits elsewhere along the western margin of Pangea. Although origin of the tectonic stress along the western margin of the late Paleozoic WCSB is poorly understood, detailed analysis of the relative mode (e.g., vertical or rotational), rate and timing of fault block movements using relatively easily identifiable Maximum Flooding Intervals (MFI) allowed delineation of three discrete basin evolution stages (proto-rift, syn-rift and post-rift) and related tectonostratigraphic units that encompass opening and closing of the extensional Stoddart Group depositional basin. Initiation of the proto-rift stage led to Golata Formation marine mudstone deposition ...
