The Blue Anchor Fault is possibly the most obvious fault 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 this is a normal fault because the Jurassic strata is younger than the MMS. This means the Jurassic strata has slid downwards to sit beside the MMS. Also near the fault in the MMS the lighter reduction horizons are dipping downwards probably due to marginal drag. The line of the fault runs along the beach, shown by the rock/sand divide.
