Geological Feature: Rock Outcrop

Description

Description A natural outcrop of celestine is a rare occurrence anywhere in Britain. The Ben Knowle outcrop is especially instructive because contacts with the host rock Tea Green Marl can be seen and there are continuous exposures of Red Marl and Tea Green Marl on the escarpment nearby that illustrate the stratigraphic setting of the mineral deposit.
