Instead of stretching across about 13.5 million years, the region\u2019s volcanic activity appears to have been concentrated into roughly 5.5 million years, placing Giant\u2019s Causeway inside a much sharper timeline of Earth history<\/a>.<\/p>\n\n\n\n The Giant\u2019s Causeway<\/a>, located on the coast of County Antrim about 60 miles from Belfast, is made of around 40,000 basalt columns. Many are famously hexagonal, giving the shoreline the look of a giant staircase slipping into the sea.<\/p>\n\n\n\n The real story begins around 60 million years ago, when molten rock<\/a> pushed up through cracks in Earth\u2019s crust.<\/p>\n\n\n\n As thick lava cooled, contracted, and fractured, it created the tightly packed columns that now draw visitors from around the world.<\/p>\n\n\n\n The myth still matters, of course. It gives the place its name and its charm. However, science is now adding a new layer to the story, and it is much bigger than one coastline.<\/p>\n\n\n\n \u201cFor decades, it was believed the region\u2019s volcanic activity, responsible for the Giant\u2019s Causeway, stretched over 13.5 million years during a time period we refer to as the Paleogene,\u201d Prof. Mark Cooper, GSNI Chief Geologist, said in the British Geological Survey statement.<\/p>\n\n\n\n \u201cOur research shows that this activity was far more concentrated, with geological processes acting much faster than previously thought.\u201d<\/p>\n\n\n\n That does not mean each stone column took millions of years to cool. Effectively, the study is narrowing the timing of the wider volcanic episode<\/a> that built the rocks of Northern Ireland, including the Antrim Plateau, the Mourne Mountains, Slieve Gullion, and the Giant\u2019s Causeway.<\/p>\n\n\n\n Why does that matter? Because it links Northern Ireland more clearly to the North Atlantic Igneous Province<\/a>, a major volcanic system whose traces are found across the North Atlantic region, including rocks as far away as Greenland.<\/p>\n\n\n\n \u201cCutting-edge analysis has allowed us, for the first time, to place the volcanic activity that led to the formation of the Giant\u2019s Causeway within a much more precise global context,\u201d Dr. Simon Tapster, a geochronologist at the British Geological Survey, said in the same announcement.<\/p>\n\n\n\n That means the causeway is not just a photogenic coastal landmark. To a large extent, it is a surviving page from a much larger geologic chapter<\/a>, when lava, shifting crust, and tectonic movement helped shape the North Atlantic.<\/p>\n\n\n\n The findings also help explain why similar volcanic rocks appear in places such as Scotland, the Faroe Islands, Greenland, and other North Atlantic landscapes.<\/p>\n\n\n\n The causeway may look local when you are standing on it with sea spray in your face, but its story is continental in scale.<\/p>\n\n\n\nA legend meets lava<\/h2>\n\n\n\n
