| Lithological Description: |
Defined by Gibbard and Preece (pp. 59-60 in Bowen, 1999) to include the fluvial and associated gravel terrace deposits of the River Stour. They defined the Chislet Member (pre-Devensian), Folkestone Battery Bed (faunal evidence suggests correlation with the Ipswichian, MIS 5e stage) and Kennington Member (Devensian). BGS maps show up to 10 aggradations above the alluvium. |
