“…Rather it suggests that beds have been let down, or sagged into the structure, as it opened. This is more consistent with the second hypothesis that the structures are gulls formed by processes of 'periglacial cambering' (Wilson and Lake, 1983; Wilson, in Whiteman et a/., 19831, the complex bending and cracking of strata at valley margins. These phenomena are widespread in Mesozoic rocks of the Midlands (Arkell, 1947;Kellaway and Taylor, 1953;Shadbolt and Mabe, 1970;Briggs et.…”

“…6) the cover sand i s overlain by 0.45 m of non-calcareous yellowish-brown silty clay with a few very angular flints, unit 6. This deposit was previously interpreted as a periglacial solifluction deposit (Wilson and Lake, 1983).…”

“…1). The sediments, soils and structures in Cowlands Farm Quarry have been the subject of extensive debate during the course of field meetings of the Geologists' Association and the Quaternary Research Association (Baker, 1983;Rose, 1983;Wilson and Lake, 1983;Whiteman et a/., 1983). Considerable disagreement was expressed over the origin and significance of the rubified unit just below the present land surface, the series of large linear depression structures into which the unit dipped, and a complex suite of sediments preserved within the depressions.…”

Pleistocene sediments and soils exposed at Stebbing in central Essex, England are described, analysed and interpreted. The sand and gravel units above Eocene London Clay and Upper Pliocene Red Crag are shown to be a high level member of the Kesgrave Formation, with a surface immediately beneath that of the Westland Green Gravels, which are tentatively assigned to the Pre-Pastonian 'a' Stage of the British Quaternary succession. The rubified, argillic soil developed in the surface of these fluvial deposits is a composite of the Valley Farm and Barham Soils and displays micromorphological evidence of several phases of clay illuviation, gleying and brMl of -ternary science clay coating disruption. Originally truncated and buried beneath Anglian gelifluction deposits, cover sand and till, the soil has been exhumed in most places by subsequent erosion. The full succession, however, is preserved within large gulls that formed by periglacial cambering prior to this erosion. More recent loess incorporation and pedogenesis have modified the exhumed soil and the materials within the gulls.
