These beds consist of alternations of sand and sandy clays, some of the sands containing glauconite grains. These beds appear to have been formed in a quiet estuary by the sediment brought down by a great river, the changes to the coarser detritus being caused by the state of flood.

GA008 P805552 Chalk sections on the Ridge Road to Hollandridge, at 550 OD. Zone of Micraster cortestudinarium. Excursion to Henley, July 13th 1912. 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.

East [on left hand side of photograph] West [on right].
GA008 P805563 Oldhaven Gap. Excursion to Reculvers, Herne Bay, July 20th 1912. The banks of this ravine differ greatly in character, the western being almost perpendicular while the eastern is an uneven slope of slipped London Clay. The western dip though slight is probably the cause of this. East [on left hand side of photograph] West [on right].
GA008 P805564 Oldhaven Gap looking north or seaward. The Oldhaven Beds which at Charlton and Erith are estuarine beds here exhibit marine forms of life such would obtain in shallow seas. Excursion to Reculvers, Herne Bay, July 20th 1912. West [on left hand side of photograph] East [on right].
GA008 P805565 The peculiar selenite crystals from the Oldhaven Beds, Herne Bay. Excursion to Reculvers, Herne Bay, July 20th 1912. The fine sand has been [?] between the plates of selenite, quite altering the appearance of the mineral. [Printed illustration.] Selenite crystals from the Oldhaven Beds, Herne Bay. These groups of selenite crystals are permeated with sand so that the usual transparency is lost.
GA008 P805566 The Woolwich Beds consist wholly of sand with no shelly or mottled clays. Excursion to Reculvers, Herne Bay, July 20th 1912. They have no definite bottom bed neither distinctive green sand or pebbles. Consequently it is difficult to fix the plane of division with the Thanet Beds.

GA008 P805573 View from the Roman Wall at Reculver looking E over the marshes. Excursion to Reculvers, Herne Bay, July 20th 1912. In Roman times this was a tidal estuary and navigable down to comparatively recent times. This old channel of the Wantsum is now a marsh three miles wide and well protected from the sea by a strong sea wall or bank. Added note: Site of Roman town Regulbium. [Arrows indicate location of the sea wall, mid-left of photograph, and Richborough distant left.].
GA008 P805574 Reculvers Church. Excursion to Reculvers, Herne Bay, July 20th 1912. In the reign of Henry VIII Reculvers Church was nearly one mile from the sea but at the beginning of the 19th century it was abandoned as a place of worship on account of its insecurity, and it would no doubt have disappeared if the cliffs had not been protected artificially from further destruction.

GA008 P805586 Locke's Brick Pit at Hartwell. Excursion to Aylesbury, Hartwell and Stone, July 27th 1912. This Hartwell Clay is not separated from the Kimmeridge Clay on the map but was probably at a higher horizon than any part of the clay of Kimmeridge cliffs. It differs from it however in being not at all shaly but sandy and glauconitic.

Above them with an apparent unconformity due to contemporaneous erosion is a bed of clay 5 to 6 feet thick with ironstone bands near the base. These sands have been bleached by the action of organic acids arising from the decomposition of vegetable matter which have run out the iron and other soluble substances leaving a nearly pure silica suitable for glassmaking.
