Charlbury-Road Quarry, Enstone. — In this quarry (33) 

 the pale-coloured marls 19 and black clay 20 are seen at the 

 top with the Lower Nerincea-Bed puzzlingly intermingled. 

 Below are the Chipping-Norton Limestones with at from 2 to 

 3 feet down a " shelly-bed," and at 9 feet down a fairly massive 

 bed, one foot thick, which is probably on the horizon of the 

 " Old Man." Below are limestones with " wavy " surfaces. 

 Large stretches of these were exposed in the floor of the quarry, 

 and are reminiscent of the waterworn surfaces of the Sully Beds 

 at Lavernock, near Cardiff. The beds probably correspond to 

 the Hook-Norton Beds, which at Great Tew are so sandy. 



Chipping-Norton Limestone is exposed in the quarries 

 numbered 34 and 35.
