Globally significant volcanic event formed Giant’s Causeway, scientists find
Geochronologists say basalt columns in Antrim sprung up during volcanic activity over 5.5m years – 8m less than thought For centuries, the tale has been passed from generation to generation: how the Irish giant Finn McCool built the Giant’s Causeway in Northern Ireland to fight Benandonner, his Scottish rival, by hurling chunks of the Antrim coastline into the sea. Now, scientists have revealed it was intense geological activity during a “major globally impacting volcanic event” – and not a legendary battle between two destructive giants – that led to the formation of the coastline’s 40,000 distinctive interlocking basalt columns about 60m years ago .
