The relationship of the Bowland shales to the pendleside limestone in the Clitheroe, Slaidburn and Sykes Anticlines

The Pendleside Limestone is redefined as comprising the B 1 (S 2 ) zone and the lower part of the B 2 (D 1 ) zone. It is argued that the Bowland Shales, including the basal beds of upper B 2 age, transgress the Pendleside Limestone northwards from Clitheroe, following a shallow earth‐movement with axes crossing the Ashnott Anticline, the Slaidburn Anticline and the Sykes Anticline. The Slaidburn Breccia is shown to be of lower B 2 age. There is unconformable overlap locally of the Lower Bowland Shales.
