Abstract

Following a recent re-mapping of the district east of Pontesford Hill, Shropshire, it now seems likely that the Uriconian and Longmyndian rocks at The Lyd Hole are faulted against one another, and that the Pontesford Shales form two outcrops, separated by faulting, and not a single outcrop as previously suggested. Doubt is cast on the validity of the so-called “rhyolite” of Habberley Brook, and the faunas and correlation of the Pontesford Shales are reviewed in the light of new evidence.
