The Residual Deposits Group is a Palaeogene to Quaternary lithostratigraphic group (a sequence of rock strata or other definable geological units) present in those parts of southern and eastern England where the Chalk outcrops and in the Buchan district of northeast Scotland. In the former they consist of the 2mto10mm (07feetto30feetm) thick remanié deposit, Clay-with-Flints and in the latter the Buchan Gravels Formation which is up to 25m (82feet) thick.[1]
