Chalk Group Lithostratigraphy: East Anglia - Wells Marl

A hitherto un-named marl in the middle of the succession exposed in an old quarry at Wells-next-the-Sea [TF 928 429], north Norfolk, and recognised in the Trunch Borehole [TG 2933 3455] at a depth of 286.55 m (Arthurton et al., 1994), is herein informally designated the Wells Marl. In the Trunch Borehole, it comprises a 60 mm thick laminated, silty, grey marl, and probably equates with Old Nore Marl of the Sussex Chalk Group succession (Arthurton et al., 1994).
