caption_attribution_description: English: Cliffs by beach at Bexhill-on-Sea in England. The sedimentary rocks of the cliff belong to the Wealden Group of rocks and they were formed about 139 to 134 million years ago during the Early Cretaceous Epoch of the Earth's geological history.
context_page_description: The Tunbridge Wells Sand Formation is a geological unit which forms part of the Wealden Group and the uppermost and youngest part of the unofficial Hastings Beds. These geological units make up the core of the geology of the Weald in the English counties of West Sussex, East Sussex and Kent.
  The other component formations of the Hastings Beds are the underlying Wadhurst Clay Formation and the Ashdown Formation. The Hastings Beds in turn form part of the Wealden Group which underlies much of southeast England. The sediments of the Weald, including the Tunbridge Wells Sand Formation, were deposited during the Early Cretaceous Period, which lasted for approximately 40 million years from 140 to 100 million years ago. The Tunbridge Wells Sands are of Late Valanginian age. The Formation takes its name from the spa town of Tunbridge Wells in Kent.
