Adjoins Fig. 27; overlaps Fig. 25. 9 = Weston Member; 10 = Betton Member; 11 = Meadowtown Member; 12=Rorrington Member; 13=Spy Wood Member; 14=Aldress Member; 20=Silurian rocks; black outcrop D=dolerite; black outcrop A = andestic intrusion of Lower Wood (SJ 30) The sole remaining outcrops of Betton Member occur in two small, immediately adjacent and largely fault-bounded areas centred about half a mile (0-8 km) north of Church Stoke, where the southerly continuation is terminated by glacial deposits forming the southern boundary of the Inlier. The original interpretation of this area was subject to some later revision by Whittard, and the present map represents his final version. The uppermost ( easterly) reaches of Spy Wood Brook expose sandy, argillaceous, flaggy beds with much volcanic dust and pyrite at Loc. 382 (Fig. 30). Fossils are not common but include Ogyginus, trinucleids, fragments of inarticulate brachiopods and poorly-preserved biserial graptolites. About 750 ft (231 m) farther south, the last outcrops of Betton Member are seen in the small valley known locally and in Whittard's Monograph and notes as Deadman's Dingle, which runs westwards into Spy Wood Brook. Several exposures, including Loc. 385, of micaceous, flaggy shales occur, some of which contain a typical fauna of graptolites and trilo- bites, while Loc. 384, in the lower part of the succession, shows c. 18 ft (5-5 m) of rusty-weathering shales rich in volcanic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
