Fig. 1 in Bashkirian rugose corals from the Carboniferous Mattson Formation in the Liard Basin, northwest Canada -stratigraphic and paleobiogeographic implications

Fig. 1. Map showing location of study area and Carboniferous lithofacies assemblages subcropping beneath Permian and Mesozoic deposits in the Western Canada Sedimentary Basin (modified from Richards et al. 1994). In the Liard Basin, western occurrences of the Rundle and Mattson lithofacies assemblages overlie and pass westward into the Besa River lithofacies assemblage. See Fig. 3 for the formational composition of the Banff, Rundle, and Mattson lithofacies assemblages.
