Abstract
Three hundred million years ago the world looked quite different with Ireland at the centre of a continent known as Pangea. It was at about this time that Pangea started to split apart creating a series of rift valleys. Eventually, this rifting split all the way through the continental crust and a new ocean basin was formed with two new smaller continents on either side: the North Atlantic, Europe and North America respectively. The gross morphological structures of the Irish deep-water seabed developed as a result of a series of rift valleys that formed during the early development of the north Atlantic starting in the Permo-Triassic geological period (around 250 million years ago).
