The boundary is drawn at the base of the lowest sand bed, conformable on silty clay with common sandy clayey silt interbeds.\r\nIn practical terms, it is taken at the ‘lowest sandy horizon mappable in the field’ (Lake et al., 1986). In London, and further to the west, sand beds appear lower in the sequence and here the base of the Claygate Member is based on other criteria including grain size and glauconite content (Ellison et al., 2004).'] |
