. Bulletin of the British Museum (Natural History), Geology. 22 W. F. WHITTARD. \ /\ Fig. 13 Geological map of the area SW of Shelve hamlet. Overlaps Fig. 14. 5 = Mytton Member; 6=Hope Member; 7 = Stapeley Volcanic Member (7a = interbedded shales); black outcrop D = dolerite. (SO 39) subequal parts by a second, subparallel fault which runs through Roman Mine and just west of Shelve hamlet. The SW part is centred broadly on Shelve Hill (Fig. 13), an elongated feature which stands notably higher than the surrounding, often badly-drained ground underlain by regressively-weathering shales of the Hope Member. Scattered exposures are most common towards either end of Shelve Hill, where three disused mines (Whitegrit, Oldgrit and Ladywell) are situated, but good sections are generally lacking. An old quarry (Loc. 670) 450 ft (137 m) NW of Whitegrit school exposes sandy, micaceous flags, weathering yellowish-grey, from which the type material of Dictyonema cobboldi Bulman (1928 : 33), together with D. irregulare Hall, was obtained. The locality was quoted by Whittard (1931 : 327) as being 330 yd (300 m) SSW of Whitegrit Mine, a misprint for SSE. About 450 ft (137 m) east of the same school, a collapsed mine shaft and its associated tip heaps of blue-hearted, shaly flags were noted by Whittard (1953 : 240) as having proved fossiliferous. The fauna includes Ogygiocaris selwynii, Monobolina plumbea (Salter), Redonia anglica, hyolithids and rare Didymograptus. In this area the linear arrangement of shafts and tip heaps running ENE between Whitegrit and Oldgrit suggests a.
