Bedrock geological map of Ireland. Layers of Upper Carboniferous sedimentary rocks, Loop Head, County Clare. The geology of Ireland consists of the study of the rock formations on the island of Ireland. It includes rocks from every age from Proterozoic to Holocene and a large variety of different rock types is represented.
Dún Briste (English: Dun Briste Sea Stack) is a natural sea stack or pilaster - in geomorphology called stack - that was formed in Ireland during the Carboniferous period, possibly Mississippian, approximately 350 million years ago.
Geological Survey Ireland produces maps, reports and databases, and acts as a knowledge centre and project partner in a number of aspects of Irish geology. [ 3 ] The organisation managed the Irish National Seabed Survey (INSS, 1999–2005), which on completion was the world's largest civilian marine mapping programme.
Variations in the strength of gravity occur from place to place according to the density distribution of the rocks beneath the surface. Such gravity anomalies have been mapped across the British Isles and adjacent areas [1] and they reveal aspects of these islands’ geological structure.

Column 4 indicates on which sheet of the Geological Survey of Ireland's 1:50,000 scale geological map series of Ireland, the fault is shown and named (either on map/s or cross-section/s or both). Column 5 indicates a selection of publications in which references to the fault may be found. See references section for full details of publication.
The geology of Ireland is diverse. Different regions contain rocks belonging to different geological periods, dating back almost 2 billion years. The oldest known Irish rock is about 1.7 billion years old and is found on Inishtrahull Island off the north coast of Inishowen [ 4 ] [ 5 ] and on the mainland at Annagh Head on the Mullet Peninsula ...
The red line shows where the Iapetus Suture extends through present-day Ireland and Great Britain. A related suture through Denmark, Poland and Ukraine is the Trans-European Suture Zone. The Iapetus Suture is one of several major geological faults caused by the collision of several ancient land masses forming a suture.
