Abstract
Summary: The unrivalled exposures of the quarry show the Forest Marble to comprise a complex association of vertically and laterally changing facies. These are interpreted to represent environments ranging from subtidal-intertidal fully marine sand shoals and hard substrates colonized by corals, to mud flats and tidal channels associated with coastal swamps. An earlier interpretation of calcarenites in the Forest Marble is inapplicable at Shipton-on-Cherwell.
