Three probably Late Devensian members of the Banchory Till Formation have been established in the Aberdeen area [[Media:P915379.png|(P915379)]], but only one is visible at the [[Nigg Bay, Aberdeen - locality, Cainozoic of north-east Scotland|Nigg Bay]] site ([[Media:P915347.png|P915347]]). The Nigg Till Member is dark greyish brown, contains clasts derived locally from the west to west-south-west and is typical of surficial tills in the lower Dee valley and to the south. The brown Kingswells Till Member is probably a local variant, having a west-south-west to east-north-east fabric and containing much ‘Hill of Fare’ granite. It is equivalent to Till B of Murdoch (1977) and its type area is the Kingswells–Culter–Aberdeen city area. A third unit, the dark grey Den Burn Member with locally derived clasts underlies the above-mentioned till in the vicinity of the Kingswells Roundabout (NJ 878 061). It has a north-west to south-east fabric and is equivalent to Till A of Murdoch (1977). It is possibly equivalent to the ‘grey boulder clay’ with clasts derived from the north-west, which Bremner (1934a, 1943) recorded as overlying ‘dark shelly boulder clay’ in excavations for the Anderson Drive Ring Road. The shelly unit is assigned here to the Banffshire Coast Drift Group (see above).

A fourth member of the Banchory Till Formation occurs in the Ellon–Bellscamphie area. This till, named here as the Bearnie Till Member, contains clasts of local provenance but is typically dark grey and contains a rich Jurassic palynoflora (Site 15 [[Ellon (Bellscamphie) - locality, Cainozoic of north-east Scotland|Ellon]]). The last two attributes are probably the result of glacial reworking of the older Pitlurg Till Formation (Banffshire Coast Drift Group). The Bearnie Till is overlain by the red, Hatton Till Formation ([[Media:P915347.png|P915347]]; [[Media:P915319.png|P915319]]).
