Reculver Sand Member

Computer Code: RCLV Preferred Map Code: notEntered
Status Code: Full
Age range: Thanetian Age (GT) — Thanetian Age (GT)
Lithological Description: The Reculver Sand Member typically comprises cross-bedded fine-grained sands, or bioturbated silty sands and sandy silts, some glauconitic, with scattered shells or shelly lenses. A thin calcareous sandstone is present at Herne Bay.
Definition of Lower Boundary: The Reculver Sand Member overlies the silty sands and silty clays of the Pegwell Silt Member at a sharp contact, with a basal shell bed in places (King, in prep.).
Definition of Upper Boundary: The Reculver Sand Member is overlain by glauconitic sands of the Upnor Formation (UPR). These can be superficially similar to the Reculver Sands, but are generally more heterogeneous, often with clay streaks and Ophiomorpha burrows, partly cross-bedded and with gravel at the base (King, in prep.).
