Shales to floor of quarry. 



Fossils here seem to be very rare and fragmentary. 



The section in the railway near Barnoldswick shows a series 

 of limestones and shales, probably belonging to the same series as 

 at Kain Hall. An examination of the railway-cutting 1 mile north 

 of Rimmington Station also shows a similar series to those 

 mentioned above. 



North of Pen die Hill the Pendleside Limestone would appear to 

 be very inconstant, being often absent or very slightly represented 

 over large areas. 



An interesting lenticular band o£ limestone appears on the north- 

 western flanks of the Grit Hill from Carlton to Booth Bridge, 

 1 mile north of Earby. Numerous sections in this patch show a 

 good deal of disturbance, and thinly-bedded limestone (hard and 

 often conchoidal in fracture) and shales. Possils are rare, one frag- 

 ment of Orthoceras Steinhaueri being the only organism obtained. 



The quarry nearElslack Free School shows thinly-bedded contorted 

 limestones, and in the quarry in the field south-west of the railway 

 (' dip-mark ' 55° on the 1-inch Geological Survey map) the beds are 

 almost vertical, but the section is small. Better sections, however, 

 are seen in the streams which unite about a quarter of a mile north of 

 Yellison House. Here is a well-marked anticlinal fold, and a feature 

 is made by it along the axis of fold. A small quarry in the same 

 rock at the head of Denindale (dip-mark 30° south-east on the 

 1-inch map) shows bands of chert in the limestone. 



It is quite probable that this band represents the Pendleside 

 Limestone. The presence of Orthoceras Steinhaueri and petrological 

 evidence favour strongly this view. 



The Lothersdale Valley is much complicated by faults, but 

 there is a large central mass or dome of limestone dipping south- 

 eastward and north-westward, of very considerable thickness : this 

 is largely quarried at Eaygill Delph and Hawshaw Delph. The 

 quarry at Park Head shows much the same section of limestone 

 also in the form of an anticlinal fold, but in addition shows a small 

 section of beds above it: black shales with Posidonomya Becheri, 

 Posidoniella Icevis, Orthoceras Steinhaueri (crushed), Glyj^hioceras 

 hilingue, and Gl. spirale. 



Fossils are very rare in all the quarries, but fine encrinital and 

 shell-detritus is met with. In the south-western part of this basin, 

 a quarry on the road to Bleara Low (marked Broom Quarry) still 

 shows an anticlinal fold in the limestone with the axis in the 

 same direction.
