character, with a very localized development of highly-fossiliferous 

 deposits, on a given horizon, constitutes a remarkable feature. 

 Eig. 4 (p. 60) illustrates the section just described. 



If the tuff occurring in this section is an attenuated portion of 

 the thick tuff seen in Tissington cutting, the Cyatha^conia-siihzone 

 attains, in this neighbourhood, a thickness of well over 200 feet. 

 About 100 feet of the subzone are represented above the tuff in 

 Tissington cutting, while a thickness of about 125 feet is seen 

 underneath the tuff in Newton-Grange cutting. 



(ii) Bradbourne. 



In the Bradbourne iulier, immediately south of the main mass of 

 limestone and 2 miles east of Tissington, numerous small exposures 

 indicate a considerable development of Dg, with an abundant fauna. 

 A quarry north of Bank House, at the eastern end of Bradbourne 

 village, shows a good section of the thin limestones, with shale- 

 partings, included in the subzone. 



(C) Sections in the South-Western Part of the Area. 



(i) Waterhouses. 



In the extreme south-west of the area, exposures showing a 

 highly-fossiliferous development of Dg are afforded by two small 

 quarries in the fields north of Waterhouses. These quarries lie 

 respectively north-east and north-west of Field House. The beds 

 consist of limestones with occasional shale-bands, chert being deve- 

 loped in the limestones. 



(ii) Warslow. 



On the western margin of the area, about 5 miles north of 

 Waterhouses, three adjacent quarries lying to the east of the 

 village of Warslow afford an extensive exposure of the upper part of 

 the Carboniferous Limestone. The vertical extent of this section 

 is over 300 feet, and the greater part, at least, must be assigned to 

 the Ci/athcLvonia-s{ibzojie, but an upward sequence into the Pendle- 

 side Series is not seen. The beds exposed consist mainly of dark, 

 thinly-bedded, cherty limestones. 



Farther east, in the Manifold Valley, near Hulme End, cuttings 

 on the light railway expose a series of thinly-bedded, cherty lime- 

 stones with interbedded shales, belonging to D3. The beds are 

 considerably folded, and no great vertical thickness is seen. 



(iii) Manor Farm^ near Wettou. 



East of the Manifold Valley, about 1| miles south-east of 

 Warslow, and nearly 1 mile north of Wetton, a very interesting 

 little section shows the uppermost beds of the Carboniferous Lime- 

 stone and the lowest beds of the Pendleside Series in conformable
