Templetown Bay
West side of Hook Head
Late Cambrian contact with overthrust and/or unconformable Devonian. Late Cambrian Cambrian Booley Bay formation is formed of thin bedded fine quartz sands, silts and shales that show small scale slumping and current ripples within sharply defined continuous beds. They show some evidence of Variscan structural deformation, including tight folding. The Devonian grades from low angle cross beds of conglomerate and coarse sands, to more steeply inclined cross bedded sands with gravels floating in this matrix.
