Dunquin Group
Silurian lithostratigraphic group in Ireland
From Wikipedia, the free encyclopedia
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
