Chalk Group Lithostratigraphy: Northern England - Ludborough Flint
This is a conspicuous, laterally very persistent tabular, locally semitabular, flint, up to 0.25 m thick, and typically pale grey or white in colour (Wood & Smith, 1978). In conjunction with the underlying Ravendale Flint, Tabular Flint, and North Ormsby Marl, it forms a mappable feature that equates with the Brandon Flint Series of East Anglia and the Basal Complex of the North Downs (Gaunt et al., 1992). The Ludborough Flint itself equates with the Floorstone Flint of the Brandon Flint Series in East Anglia (Gaunt et al., 1992).
