This is a list of the named geological faults affecting the rocks of Northern Ireland.

Terminology[edit]

See the main article on faults for a fuller treatment of fault types and nomenclature but in brief, the main types are normal faults, reverse faults, thrusts or thrust faults and strike-slip faults.

Key to table[edit]

  • Column 1 indicates the name of the fault. Note that different authors may deploy different names for one and the same feature, or a part of a feature. Conversely the same name may be applied to two different features, particularly in the case of smaller faults with a wide geographic separation.
  • Column 2 indicates the county in which the fault occurs. Some traverse two or more counties of course.
  • Column 3 indicates the Irish grid reference for the approximate midpoint of the fault (as mapped). Note that the mapped extent of a fault may not correspond to its actual extent.
  • Column 4 indicates on which sheet of the Geological Survey of Northern Ireland's 1:50,000 scale geological map series of Northern Ireland, the fault is shown and named (either on map/s or cross-section/s or both). Some of the faults are also depicted on the 1:250,000 scale geological map of Northern Ireland.[1]
  • Column 5 indicates a selection of publications in which references to the fault may be found. See references section for full details of publication.
