Transition from fluviatile to tidal-marine sediments in the Upper Devonian of Seven Heads Peninsula (South County Cork, Ireland)

Abstract

Along the east coast of Seven Heads peninsula (southern Ireland) a more than 1000m thick north dipping succession of Upper Devonian strata is investigated. The lithology and sedimentary structures of the facies types are described and briefly compared with recent sediments. They indicate a gradual transition from a continental "Old Red Sandstone" facies along a coastal plain facies into overlying (tidal) marine facies.
