Chalk Group Lithostratigraphy: Northern England - Ravendale Flint

This is the lowest tabular flint in the Chalk Group of northern England, although it might sometimes be semitabular, and locally occurs as huge elliptical masses (Wood & Smith, 1978). It is up to 0.25 m thick, and is named after West Ravendale Quarry [TF 227 999] (Wood & Smith, 1978). In conjunction with the overlying Triple Tabular Flints, North Ormsby Marl and Ludborough Flint 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).
