Figure 15.1

Map of Western Canada illustrating the location of various tectonic elements, including numerous faults affecting distribution of Upper Carboniferous and Permian units, as well as the lines of schematic cross sections depicted in Figures 15.3 and 15.8. Distribution of known faults was compiled by Richards, Halbertsma, and Barclay from seismic and lithostratigraphic data. The Peace River Embayment occupies a portion of the Interior Cratonic Platform.

Figure 15.2

Correlation chart illustrating standard chronostratigraphic units, positions of four sequences discussed in the text, conodont biozonal scheme, and Upper Carboniferous and Permian lithostratigraphic units from southeastern British Columbia to the southwestern District of Mackenzie. Question marks indicate that the position or nature of contact is uncertain (modified from Henderson, 1989). R., Rhachistognathus; S., Streptognathodus; N., Neogondolella; Ns., Neostreptognathodus.

Figure 15.16

Distribution of Permian (and subjacent Upper Carboniferous) carbonate. Regions shown as "High" carbonate are so located because they include a large proportion of the Ksituan Member within the Belloy Formation, especially for the western portion of the map.
