Summary

A study of the Ordovician rocks on the northern side of Abereiddy Bay has revealed that the succession is locally overturned. Consequently the stratigraphic levels of two horizons are reassessed—the Castell Limestone is placed above the Dicranograptus Shale, and the Llanrian Volcanic Series is allocated to the Lower Llanvirnian.
