Caption: Chalk sections on the Ridge Road to Hollandridge, at 550 OD. Zone of Micraster cortestudinarium. Excursion to Henley, July 13th 1912.
Description: For the most part these tabular flints seem to follow the bedding planes but in this section they are all double, the two halves enclosing a layer of white powder of varying thickness largely composed of long sponge spicules. These comparatively horizontal layers of flint separate and converge irregularly so that the amount of Chalk included between two 'tabulars' may be over a foot in one place and almost touching in others.
