Chalk Group Lithostratigraphy: Northern England - Little Weighton Marls

Jump to navigation Jump to search

These comprise three marls in a c. 3 m thick chalk interval, and are the first thick marl bands that occur above the Kiplingcotes Marls (Gaunt et al., 1992). The lowest two marls are the best developed (c. 20 mm thick), and probably equate with the East Cliff Marls of the North Downs Chalk Group succession and the Shoreham Marls of Sussex; the upper of the two Shoreham Marls marks the base of the M. coranguinum Zone in southern England (Gaunt et al., 1992). Little Weighton Marl 3 is thinner (c. 10 mm), and overlain by an acme of the inoceramid bivalve Volviceramus koeneni, probably equating with a calcarenitic chalk bed containing V. koeneni and Platyceramus c. +1 m above the upper East Cliff Marl in the North Downs (Gaunt et al., 1992).
