ST0343 : The Blue Anchor Fault
taken 13 years ago, near to Old Cleeve, Somerset, England
The Blue Anchor Fault
Possibly the most obvious fault line in Britain. The red rock with reduction horizons is Triassic Mercia mudstone (MMS), to the left is Jurassic interbedded marls and muds (with evaporites like gypsum). You can tell that this is a normal fault because the Jurassic strata are younger than the MMS. This means the Jurassic strata have slid downwards to sit beside the MMS. Also near the fault in the MMS the lighter reduction horizons are dipping downwards; this is probably due to marginal drag.
The line of the fault runs along the beach, shown by the rock/sand divide.
