Open publisher page 13 citations

Abstract

Shirley and Horsfield (1940) in describing the Carboniferous Limestone of the Castleton-Bradwell area in North Derbyshire submitted evidence that the richly fossiliferous rocks of B2 age, the “Castleton reef knoll limestones lie with strong unconformity on the D1-D2 limestones, being piled against steep slopes or cliffs of Mid-Carboniferous age of at least 550 feet. The Nun Low limestones of P age follow with a similar relationship to the Castleton Limestones”.
