Figure F3. A. Facies model for anastomosed river sedimentation from the Potomac Formation (modified from Miall, 1996). Photographs are examples of each facies in a core from given levels in the Fort Mott borehole. B. Facies model for delta plain sedimentation from the Potomac Formation (modified from Reading, 1986). Photographs are examples of each facies in a core from given levels in the Fort Mott borehole.
