Clogher Head Formation - Geological Survey of Ireland
... Most of the rocks in the section are Silurian (Llandovery–Wenlock) in age, comprising coarse–fine-grained calcareous greywackes of the Clogher Head Formation that pass in the south into mudstones of the overlying Red Man’s Cove Formation. Both formations are intruded by Caledonian lamprophyre dykes. ...
