Abstract

A conglomerate band exposed in Gullet Quarry, at the southern end of the Malvern Hills, contains a layer of shelly limestone in which are embedded large, often angular, boulders of Malyernian rock. The character of the limestone and the form and distribution of included boulders suggest that a near-shore environment of carbonate deposition was continually supplied with clastic material from adjacent sea-stacks. The limestone has yielded a conodont fauna indicative of a Llandovery age earlier than that assigned to the conglomerate by Reading and Poole (1961) on the basis of brachiopod evidence.
