—Upper WD4 to WI1.1 strata at the Nikanassin Range. a) Truncation of underlying clinoforms by the WD4.2.1 surface, overlain by a wedge of onlapping/downlapping intraclastic grainstones (positions 5–8, Fig. 13a). b) Massive grainstone to boundstone margin of the WI1 above the erosional WI1.1 sequence boundary. Dips above the orange arrows represent true dip; shallower dips above the green arrow represent a change in progradation direction; dipping WI1.2 surface cuts down into the WI1.1 (position 13, Fig, 13a and far right of Fig. 13b). c) WI1.1 sequence boundary tracks the basinward-dipping surface of uppermost WD4. Wedge of grainstone between the sequence boundary and the trangressive surface (TS) represents an in situ lowstand deposited during rising sea level.
