The “Red Rock Fault”, Cheshire: A critical review

The credentials of the so-called Red Rock Fault, along the eastern border of the Cheshire Plain, and at the boundary between the Trias or Permo-Trias on the west, and the Carboniferous rocks on the east, are examined from the published records. The conclusion reached is that the boundary probably represents an unconformity, not a fault. It may be taken to be a test case as to the authenticity of other well known and long established ‘faults’ in the structure of Britain.
