List of shear zones of Great Britain

This is a list of the named shear zones affecting the rocks of Great Britain and the Isle of Man. See the main article on shear for a fuller treatment of shear in rocks.

Key to tables

edit
  • Column 1 indicates the name of the shear zone. Note that different authors may use different names for the same shear zone or a section of it.
  • Column 2 indicates the OS grid reference of the approximate midpoint of certain shear zones. Note that the mapped extent of a shear zone may not accurately reflect its actual extent.
  • Column 3 indicates the country in which the shear zone occurs.
  • Column 4 indicates the county in which the shear zone occurs. Some traverse two or more counties of course.
  • Column 5 indicates on which sheet, if any, of the British Geological Survey's 1:50,000 / 1" scale geological map series of England and Wales (E&W) or of Scotland (Sc), the shear zone is shown and named (either on map/s or cross-section/s or both). A handful of BGS maps at other scales are listed too.
  • Column 6 indicates a selection of publications in which references to the shear zone may be found. See references section for full details of publication.
