Stratigraphy
Geological group: | Wealden | Formation: | Wadhurst Clay | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: The Wadhurst Clay Formation of the Hastings Beds Subgroup has an ages of Lower Valanginian according to Radley (2006; vide Allen & Wimbledon 1991) |
Lithology and environment
Primary lithology: | claystone |
Includes fossils? | Y |
Environment: | lacustrine - small |
Geology comments: Shallow, freshwater to slightly brackish lakes, including horsetail ‘reed’ bed and terrestrial fauna. Fossils throughout the Wadhurst Clay Formation include ostracods, conchostracans (‘clam-shrimps’), pond-snails and the low-salinity bivalve Neomiodon. Widespread siltstone and fine sandstone gutter- and scour-fills indicate storm activity and/or fluvial runoff into the Wadhurst lakes (Radley 2006) |
