300 million year old volcanoes have been discovered near Mullingar. The Geological Survey’s Tellus Programme has uncovered the ancient history of counties Roscommon, Longford and Westmeath.
The maps reveal that there are 300 million year old volcanoes beneath the border of Westmeath/Offaly. The survey was carried out by low flying aircrafts which showed magnetic rocks deep beneath the surface. These aircrafts can see through glacial deposits as well as peat.
“Tellus continues to reveal extraordinary new detail in Ireland’s geological landscape buried beneath our feet, building upon existing data gaps and developing natural resource opportunities,” said Geological Survey of Ireland principal geologist Ray Scanlon.
Tellus is currently surveying over counties Offaly, Kildare, Meath, rural county Dublin and northern parts of Wicklow and Laois is almost 60 per cent complete. They have now turned their attention to County Dublin.
