"Diamicton and sandy diamicton with subsidiary chalk-rich diamicton. Stratified superficial deposits. Occurs onshore. Formed during the Mid Pleistocene (Quaternary Period) (.78-.126 Ma BP)."@en . "HATI"@en . "Brown silty sandy clay diamicton incorporating masses up to at least 100m across of \"marly drift\". The brown diamicton is apparently massive and contains much flint, quartz and quartzite, sediments of Cretaceous, Jurassic, Permo-Triassic, Carboniferous and Devonian derivation, and igneous erratics \"marly drift\" is pale grey or buff massive highly consolidated diamicton consisting almost entirely of re-constituted chalk and black hearted fresh flints, with minor Jurassic input. The Hanworth Member contrasts with other sandy tills of the Sheringham Cliffs Formation in that it is not contorted."@en . . . "Hanworth Till Member"@en . "To c.25m"@en . . . "0.126"^^ .
