East Quantoxhead Fault

Somerset, UK 


Sea cliffs (~ 20 m high) and wave-cut platform between East Quantoxhead and Blue Ben, ~ 18.3 km WNW of Bridgwater. Liassic (top Triassic and Lower Jurassic) limestones and shales are displaced by the East Quantoxhead Fault, which has a net normal displacement of ~ 50 m down to the south. Folding and thrusting in the hanging-wall indicated that the fault was partly "inverted", probably during Alpine contraction (Tertiary). Gentler folding also occurs in the footwall.
