Rock patterns on the beach at Seaton – Part 1

Boulders on the beach at Seaton: Seaton Beach looking west showing large boulders (rock armour) positioned at the base of  the red Triassic Mercia Mudstone cliff to stop further erosion, in Devon, U.K. on the Jurassic Coast (1)

Seaton is a charmingly old-fashioned seaside resort in Devon, U.K. on the Jurassic Coast World Heritage Site. Geologically it is well known for its red Triassic Mercia Mudstone and adjoining Cretaceous Chalk and Greensand cliffs. The Mercia Mudstone is very soft and fast wearing away. In an attempt to slow down the eroding and under-cutting effect of the waves, a bank of large boulders has been placed on the flint and chert shingle beach at the base of the cliffs. These boulders represent a range of presumably fairly local rock types and some of them are beautifully coloured and patterned. This post shows one particular boulder exhibiting a variety of different textures and geological compositions with natural abstract patterns in red, yellow and white.
