A leading expert has put forward a bold new theory
The formation event behind Northern Ireland’s world-famous Giant’s Causeway may have taken just a few days rather than thousands of years, according to a new theory.
The scientific explanation, widely accepted for decades, is that a river valley was filled with lava that ponded to a greater depth than normal. As the thick layer of lava cooled and solidified it formed these regular columns. Dr Simms said: “An analogy I find helpful when explaining this involves cake. Eroding a river valley is rather like cutting through a layer of cake to reveal layers beneath the surface.
Dr Simms explained he first started thinking about the theory while leading a field trip to the World Heritage Site in 2012. “I had visited the Giant’s Causeway many times before, and until that moment I had just accepted the previous theory. It goes to show that even at world famous landmarks such as this, new discoveries can be made from a simple observation.”
“It highlights just how marvellous, magnificent and mysterious a geological formation we have here in Northern Ireland to share with the world,” he said.
