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.
Geological Survey Ireland is a division of the Department of Communications, Climate Action and Environment and is based in Booterstown in Dublin. [4] Its multidisciplinary staff work in sections such as groundwater, bedrock mapping (consisting of bedrock and quaternary/geotechnical), information management, heritage, marine and minerals.
The island is formed of a granitic gneiss, a type of metamorphic rock, which is known as Inishtrahull Gneiss.It is dated at 1.7 billion years old, making it Paleoproterozoic in age, and is the oldest known rock on the Irish Islands.
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
In 1992, Coffin and Eldholm initially defined the term "large igneous province" as representing a variety of mafic igneous provinces with areal extent greater than 100,000 km 2 that represented "massive crustal emplacements of predominantly mafic (magnesium- and iron-rich) extrusive and intrusive rock, and originated via processes other than 'normal' seafloor spreading."
OneGeology is an international collaborative project in the field of geology supported by 118 countries, UNESCO, and major global geoscience bodies.It is an International Year of Planet Earth flagship initiative that aims to enable online access to dynamic digital geological map of the world for everyone.

The 22 maps of the Geological Atlas of the World were co-published by CGMW and UNESCO from 1974 to 1984. In January 1983, the wall map concept of the Geological Map of the World was revived at the UNESCO G.A. [10] and the 1st edition at 1:25M scale was published in 1990. For the first time, continental geology was shown, alongside ocean geology ...
