Foundation GeologyThis segment provides an overview of the geology of the Sidmouth area in East Devon, focusing on the different rock formations present and their origins. It highlights the area's diverse geological history, spanning from the Permian to the Cretaceous periods, and emphasises the significance of the coastal exposures for understanding Earth's ancient past. It also delves into specific formations like the Otter Sandstone, Sidmouth Mudstone, and Upper Greensand,… Click to find out more ... |

Otter SandstoneThe Otter Sandstone Formation is a geological formation of Middle Triassic (Anisian) age (c. 247 to 237 million years ago). It is now referred to as the Helsby Sandstone Formation. It is exposed along the south-east Devon coast in south-west England, part of the 'Jurassic… click for far more information on this topic |

Sidmouth MudstoneThe Sidmouth Mudstone Formation is a geological formation of Mid Triassic (Anisian to Ladinian) age (c. 247 to 237 million years ago). It is the basal formation of the Mercia Mudstone Group, which is a widespread unit in England and Wales. The Sidmouth Mudstone… click for far more information on this topic |

Upper GreensandThe Upper Greensand Formation is a Cretaceous geological formation of Albian to Cenomanian age (c. 113 to 93.9 million years ago). It is found within the Wessex Basin and parts of the Weald Basin in southern England. It overlies the Gault Clay and underlies the Chalk… click for far more information on this topic |

Coastal ShingleCoastal shingle (also known as beach pebbles) is a type of sediment composed of rounded, smooth stones. It is found on beaches and coastlines around the world. Coastal shingle is formed when larger rocks are broken down by wave action and erosion. The waves and currents… click for far more information on this topic |

OverriddenThere are many areas around the town where the foundation geology has been totally overridden by human activity and development and so has no direct influence on the plant and animal species present. Examples of this obviously include housing, the town parks, gardens and… click for far more information on this topic |
