The term Plenus Marls (as ‘Actinocamax plenus marls’) was first used by Rowe (, p. ) for the marly unit at the top of the Lower Chalk that had usually been called the belemnite marl ever since Fig. 1. Locality map showing positions of English sections mentioned in .   The textural groups recognised in chalk marls are as follows: Group 1: the most poorly cemented marls (Texture Index range ; average average Intact Dry Density Mg/cu.m: some exceptionally soft marls have a Texture Index of 25 and Intact Dry Density of Mg/cu.m): These are the soft or very weak, plastic and friable marls with.

The Chalk Group (often just called the Chalk) is the lithostratigraphic unit (a certain number of rock strata) which contains the Late Cretaceous limestone succession in southern and eastern England. The same or similar rock sequences occur across the wider northwest European chalk 'province'. It is characterised by thick deposits of chalk, a soft porous white limestone, deposited in a marine. Another point of interest are the Plenus Marls, a band of darker-grey chalk (c.8m thick) located in the uppermost portion of the Zig Zag Chalk Formation. From Hedge Ledge the gradual dip of the chalk brings the Plenus Marls to beach level a short distance east of the lighthouse (fig.5 below-left).
