Chalk Group Lithostratigraphy: Northern England - Easthorpe Tabular Flints

These consist of three prominent tabular flints in a c. 1 m chalk interval, underlain by flaser bedded chalks with the trace fossil Zoophycos and the echinoids Micraster and Echinocorys, and overlain by a c. 2 m bed of laminate chalk with flattened burrow-form flints (Gaunt et al., 1992). They are laterally variable in thickness and habit, sometimes being solid or carious (Gaunt et al., 1992).
