Critical Sections in a Carboniferous Reef Knoll
Published online by Cambridge University Press: 01 May 2009
Extract
A study of the structure and petrography of the limestones exposed at Hall Hill, in Bowland, enables the geometry of part of a Carboniferous reef knoll to be defined. The main features are a central mound-like core of unbedded, poorly fossiliferous calcite mudstone and a peripheral area of bedded calcite mudstones with original, depositional dips. Thick, well-bedded coarse crinoidal limestones were subsequently bedded over the underlying knoll.
