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.
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.
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.

Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.

Provenance, also known as geographic attribution, in geology refers to the origins or sources of particles within sediment and sedimentary rocks. [1] Metamorphic, and igneous rocks are broken down via weathering and erosion into sediment as part of the rock cycle. These sediments are transported by wind, water, ice, or gravity, before being ...
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model.Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing ...
The letters A and B at the top correspond to the line labeled A--B on the smaller map. In this example, the vertical scale is exaggerated compared to the horizontal scale. A cross section or cross-section , in geology , is a diagram representing the geologic features intersecting a vertical plane , and is used to illustrate an area's structure ...
