Typically black and dark grey, weakly calcareous, matrix-supported. The matrix contains a rich Mesozoic (principally Jurassic and Lower Cretaceous) palynoflora. Clasts are of pebble grade and typically subangular to rounded and composed of quartzitic and psammitic metasedimentary rocks, with sparse felsite, chalk and shell fragments. Deformed and attenuated beds and rafts of pinkish yellow fine-grained, slightly pebbly, sand are locally common. Interpreted as having been initially deposited as subglacial till but subsequently, at least in part, glaciotectonically deformed and rafted into position during a subsequent glacial event."@en . . "Element of Kirkhill Upper Till [Obsolete: use CORSE]"@en . . "To 4.7m"@en . "The lower boundary of the diamicton is complex due to its, in part, glaciotectonic emplacement. In some situations it rests with an unconformable, undulatory, sharp to gradational basal contact on brown diamicton of the Rottenhill Till Formation. (It might also include a leaf of the overlying Hythie Till Formation, e.g. northeast face, Leys Quarry (disused). In other situations (e.g. north face, Kirkhill Quarry) its basal boundary is seen as a sharp, planar, subhorizontal, erosion surface on red felsitic gravel of the Corsend Gelifluctate Bed."@en . "The upper boundary of the diamicton is also complex. In some situations (e.g. northeast face, Leys Quarry (disused) it displays a sharp to gradational, interdigitating (glaciotectonic) upper and lateral contact with brown diamicton of the Hythie Till Formation within which it occurs as attenuated masses and rafts. Where overlying diamicton of the Hythie Till Formation is locally absent the Corse Diamicton Formation occurs at the present ground surface. In other situations (e.g. north face, Kirkhill Quarry (infilled) the diamicton's upper boundary is a sharp, erosional, channelised surface and it is overlain by the Kirkhill Church Sand Member.
