Upper Bala Series. The Ashgill Shales of Sedgwick and Salter succeed the Coniston Limestone, and have a very different fauna. They are never more than 200 feet thick, and consist of a lower stage of grey crystalline limestone, succeeded by poorly cleaved bluish or blackish shales.

(iii) Pale green and purple shales, the equivalents of the Tarannon shales of Wales, (i) and (ii) must be correlated with both Upper and Lower Llandovery (May Hill) of the Welsh area. The thickness of the whole is about 250 feet in places. The beds appear to have been deposited in somewhat shallower water in parts of the Craven area (Austwick), but are otherwise similar.
