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. [1] Dún Briste sea stack
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 ...

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.
After a wide gap in geological time, the next exposed sequences are from the Quaternary period, and consist of unconsolidated tills, boulder clays and deposits of sand and gravel. [2] The geopark encompasses about 25 km (16 mi) of coastline south of the Comeragh Mountains, extending from Stradbally to Kilfarrasy. The area is a plain, mostly ...
