300m-year-old volcanoes discovered near Mullingar
Geographically, Ireland is often likened to a saucer: upturned at its mountainous edges and flat in the middle. But that reading doesn’t take account of newly discovered volcanoes south of Mullingar.
The Geological Survey of Ireland's Tellus Programme has unearthed aspects of the long buried history of counties Roscommon, Longford and Westmeath.
The maps, generated in Geosoft Oasis montaj, reveal new detail of 300 million-year-old volcanoes on the Westmeath/Offaly border, which appear in the new airborne geophysical data as a cluster of small magnetic bodies.
The survey, conducted using low flying aircraft, also shows prominent bands of highly magnetic volcanic rocks several kilometres deep near Strokestown, Co Roscommon, which are associated with a major geological fault that can be traced through Ireland to Scotland.
The researchers say these structures are considered important in the development of mineral deposits and their location will be of considerable interest to exploration companies.Read the article in The Irish Times. Learn more about the Tellus findings on Earth Explorer.
