Facies relationships in a tidally influenced environment: A study from the Eocene of the London Basin

Abstract

The sedimentology and burrow associations of a lower Tertiary (Lutetian and Cuisian) section in south-east England are described and compared with bedding types described from the Wadden Sea and Rhine estuary. In the lower part two facies are distinguished representing channel and bank deposits. Their relationship, bed forms, fauna and general lack of bioturbation suggest deposition in an inshore tidally influenced region. The sequence is truncated by bioturbated glauconitic sediments of the transgressive Bracklesham Beds.
