Globally significant volcanic event formed Giant’s Causeway, scientists find

Geochronologists have discovered that the iconic Giant's Causeway in Northern Ireland, previously attributed to a mythical battle between giants, was actually formed by intense volcanic activity. This significant volcanic event occurred approximately 60 million years ago, a substantial revision from the previously estimated 65.5 million years, meaning the basalt columns developed over 5.5 million years—8 million years less than previously thought. The Antrim coastline's distinctive 40,000 interlocking basalt columns are now understood to be the result of a "major globally impacting volcanic event," rather than the legendary Finn McCool's battle with Benandonner. This new scientific finding provides a clearer understanding of the geological history of this famous landmark.
