Southern Region Chalk Group Lithostratigraphy: Sussex lithostratigraphy of Mortimore (1986a) - Beeding Beds
The Beeding Beds, c. 8 m thick, are marked by the top surface of the Hope Gap Hardground at the base, and by the top surface of the upper Beeding Hardground at the top (Mortimore, 1986a). Most of the succession comprises rather soft, weakly nodular, flinty chalk, capped by two beds of hard, nodular chalk and associated hardgrounds (Beeding Hardgrounds) (Mortimore, 1986a). The Beeding Marl occurs near the base, a short distance above the Hope Gap Hardground (Mortimore, 1986a).
The fauna of the Beeding Beds is characterised by the echinoids Micraster cortestudinarium and Tylocidaris, and the inoceramid bivalve Cremnoceramus crassus (formerly schloenbachi) (Mortimore, 1986a).
