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.
The term also applies to a line plotted on a geological map to represent a fault. These fractures tend to occur when a slip surface expands from a fault core, especially during an earthquake . This tends to occur with fault displacement, in which surfaces on both sides of a fault, known as fault blocks , separate horizontally or vertically.
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 .
It includes the following linear features (sorted from the north-east): The Fennoscandian Border Zone (FBZ) in Skagen and Kattegat; The Sorgenfrei-Tornquist Zone (STZ), including many parallel horsts in Scania (e.g. Linderödsåsen and Söderåsen). This zone experienced extension in the Jurassic.
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 thin red circular contour line in the middle of the map indicates the top of the oil reservoir. Because gas floats above oil, the thin red contour line marks the gas/oil contact zone. 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 ...
Simplified map of a ridge (R)–trench (T)–transform fault (F) triple junction of tectonic plates A, B, and C, with arrows indicating direction of plate movement A triple junction is the point where the boundaries of three tectonic plates meet.
