Named forDunquin

The Dunquin Group is a Silurian lithostratigraphic group (a sequence of rock strata) in the Dingle peninsula, Munster, Ireland. The name is derived from the village of Dunquin (Irish: Dun Chaoin) where the strata are exposed within an inlier on hillsides and in coastal sections at the extreme western end of the peninsula.[1]

Lithology and stratigraphy

The Group comprises siltstones, slates and a variety of extrusive igneous rocks from the Croaghmarin, Drom Point, Mill Cove, Clogher Head, Ferriter's Cove, Foilnamahagh and Coosglass Slate formations of Silurian age. The siltstones are frequently fossiliferous.
