The overlying marl/limestone succession is inferred to represent the West Melbury Marly Chalk, although the basal units appear to be in the ''M. dixoni ''Zone, suggesting that the ''M. mantelli ''Zone is faulted-out/thin/condensed.

The lower part of the succession, at the southern end of the quarry, is less fossiliferous with flints that are more tabular in character, with some sponge-bearing chalk.

This contrasts with the firm, smooth-textured, blocky chalk found in the central part of the pit, and suggests the presence of a fault.

The specimens of Entolium and Plagiostoma are in hard, silty, glauconitic chalk, at the base of the succession. The remainder of the fauna is from interbedded marls and limestones.
Interpretation: The hard, silty, glauconitic unit, with ?Entolium and ?Plagiostoma, is inferred to represent the Upper Greensand. The overlying marl/limestone succession is inferred to represent the West Melbury Marly Chalk, although the basal units appear to be in the M. dixoni Zone, suggesting that the M. mantelli Zone is faulted-out/thin/condensed.
Conclusion: ?Upper Greensand and Grey Chalk Subgroup, West Melbury Marly Chalk Formation; ?Late Albian and Lower Cenomanian, M. dixoni Zone.

The northern end of the quarry, exposing the higher part of the succession, is relatively fossiliferous chalk, with large, elongate nodular flints. The lower part of the succession, at the southern end of the quarry, is less fossiliferous with flints that are more tabular in character, with some sponge-bearing chalk.
The interval between the succession containing Volviceramus and that containing the remainder of the fauna is quite thin given the thickness that typically separates these close juxtaposition.

(44) Brash on path 290 m southwest of Warren Farm, Pewley Down, 1.37 km ESE of Guildford Castle.
1:10 000 TQ04NW NGR: TQ 0112 4920

(45) Brash at top of southern face of old chalk pit in fallen tree, 2.00 km WNW of St Martha's Hill Church, 1.18 km NE of Shalford Church.
1:10 000 TQ04NW NGR: TQ 0081 4856
Specimen nos: ARF 2787 – 2790
The specimens comprise the brachiopod Orbirhynchia mantelliana and an oyster.
Interpretation: This locality has subsequently been visited by MAW (fauna yet to be reported), and this confirms the presence of the boundary of the West Melbury Marly Chalk and Zig Zag Chalk formations near the top of the south face of this chalk pit. The Orbirhynchia appear to represent part of the Upper Orbirhynchia mantelliana Band (e.g. Mortimore et al, 2001, fig. 3,119), collected from a level close to the base of the Zig Zag Chalk Formation.
Conclusion: Grey Chalk Subgroup, upper West Melbury Marly Chalk / basal Zig Zag Chalk.

(48) Brash in base of old pit, Pewley Down, Guildford, by path, 2.22 km WNW of St Martha's Hill Church, 1.33 km NE of Shalford Church.
1:10 000 TQ04NW NGR: TQ 0067 4890
Specimen nos: ARF 2793 – 2795
The specimens include:
Bryozoa: bryozoan
Bivalvia: oysters
Echinoidea: Micraster coranguinum
Interpretation: The fauna suggests Seaford Chalk Formation or younger. However, this locality was recently visited by MAW (December 2014; results yet to be reported), and good nodular chalk (cf. Lewes Nodular Chalk), with sponge remains and a terebratulid brachiopod was found at the western margin of this pit. This contrasts with the firm, smooth-textured, blocky chalk found in the central part of the pit, and suggests the presence of a fault.
Conclusion: White Chalk Subgroup, Seaford Chalk Formation or younger.

Specimen nos: RKW 250 – 251
The specimens comprise the inoceramid bivalve Mytiloides? and a terebratulid? brachiopod, in moderately hard chalk.
Interpretation: Probably Mytiloides spp. Zone and Holywell Nodular Chalk, but morphology of Mytiloides is unusual. The possibility of a late Turonian age (suggesting Lewes Nodular Chalk) cannot be excluded. Field relations appear to favour Holywell Nodular Chalk.

Conclusion: White Chalk Subgroup, ?lower Newhaven Chalk Formation.
