'\V â 03 33 34 Fig. 17 Geological map of the area between Leigh Manor and Leigh Hall. Overlaps Figs 15, 16, 17. 6=Hope Member; 7=Stapeley Volcanic Member (7a=interbedded shales); 8 = Stapeley Shale Member; 9=Weston Member; 20 = Silurian rocks; black outcrop D = dolerite. (SJ 30) suddenly widens and is bounded on its SW side by a fault which cuts out the Stapeley Volcanic and Shale Members. Most of the vicinity of The Bog lacks exposures but a stream flowing west and SW near Ritton Farm and Ritton Castle (Fig. 22, p. 33) shows several exposures of shales, flags and occasional tuffs finally mapped by Whittard as Hope Member, though his notes at one time attributed them to the Stapeley Volcanic Member. The outcrop around The Bog and, immediately to the north, Pennerley (Map) is shown as being cut medially by an almost north-south fault which then curves slightly NNE coincident with the elongated dolerite intrusion of Buxton Hill (Fig. 7, p. 13) and is intersected by another fault extending from Shelve hamlet NE to Maddox's Coppice (Map and Fig. 11). North-east from Buxton Hill an elongated outcrop has been mapped along the eastern limb of the Ritton Castle syncline, but the junction with the subjacent Mytton Member is not well exposed, though out- crops of the latter are relatively abundant to the east. A quarter of a mile (0-4 km) west of Crows- nest, a stream runs north through Josey's Wood (see Fig. 10, p. 18) and eventually joins Hope Valley Brook. Just SE of the point where the stream cuts the unconformable Silurian rocks (Map), massive, blue-black shales of the Hope Member exposed in the stream valley produced graptolites and trilobites (mostly Pricyclopyge binodosa (Salter) but occasionally Corrugatagnostus and Stapeleyella), a fauna considered at one time by Whittard (1931 : 327) to be especially characteristic of what wer
