Bathampton Gravel Member

Computer Code: BAV1 Preferred Map Code: notEntered
Status Code: Full
Age range: Wolstonian Stage (QO) — Ipswichian Stage (QI)
Lithological Description: The Bathampton Gravel Member comprises gravels, 3 m thick, with a surface of about 3-5 m above the present River Avon. It is considered to be no younger than MIS 6 (Campbell, p. 77 in Bowen, 1999). The Bathampton Palaeosol is a cryoturbated, rubified clay-rich soil developed on the Bathampton Gravel Member. It is correlated probably with MIS 5e (Hunt, 1990; Campbell, p. 77 in Bowen, 1999).
