Overlaps Fig. 20. 6=Hope Member; 7 = Stapeley Volcanic Member (7a = interbedded shales); 20 = Silurian rocks; black outcrop D=dolerite; vertically shaded outcrops=Cwm-Mawr picrite. (SO 29, SO 39) the Stapeley Volcanic Member extends south beyond Lan Fawr and another, slightly larger one runs south along the eastern flanks of the intrusive andesite masses of the hill called Roundton (sometimes written as The Roundtain) and Todleth Hill. Faulting at the NE end of Stapeley Hill cuts out most of the Stapeley Volcanic Member until one reaches the vicinity of Bromlow Callow and The Park, about a mile (1 -6 km) east of Meadow- town (Figs 16, 27, p. 40), where lithic tuffs (including Locs 908-9) are folded into a syncline, truncated to the north by a sigmoidal east-west fault which skirts the south side of Luckley Hill. From there the rocks of the Stapeley Volcanic Member form a strip-like outcrop, 'stepped' at intervals by small faults, which extends (Fig. 17, p. 28) to the northern boundary of the Inlier just north of Leigh Hall (not to be confused with Leigh Manor, a building situated 2620 ft (799 m) at 329° true from the Rectory at Hope). Whittard's map shows the succession within the Volcanic Member north of Luckley Hill to be similar to that of Stapeley Hill, that is with a single shale horizon separating two sets of volcanics. On the other hand at Luckley Hill itself, a fault-bounded area shows apparently a more complex sequence of two shales separating three volcanic horizons, the topmost one of which contains a further subsidiary bed of shale.
