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 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.
Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole.
Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation or natural beauty, are defined as natural heritage.

Geological maps of County Donegal show rock alignments running south-west to north east across the Fanad peninsula. The underlying rock in the peninsula is mostly of Dalradian meta-sedimentary rocks, which have been exposed by weathering and erosion over the millennia There are areas of Granodiorite igneous rocks across the northern end of the peninsula from Ballywhoriskey to Fanad Head, but ...
Digital geologic mapping is the process by which geological features are observed, analyzed, and recorded in the field and displayed in real-time on a computer or personal digital assistant (PDA). The primary function of this emerging technology is to produce spatially referenced geologic maps that can be utilized and updated while conducting ...
The trip really begins in the unincorporated town of Christmas Valley, population 1,313. Just outside of town, turn left at a pointer and follow Crack in the Ground road a bumpy 7.2 miles of ...
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.
