Daylesford Sand and Gravel Member

Computer Code: DAY Preferred Map Code: notEntered
Status Code: Full
Age range: Quaternary Period (Q) — Quaternary Period (Q)
Lithological Description: Flint-bearing sands and gravels forming a terrace in the upper reaches of the Evenlode.
Definition of Lower Boundary: Around Bledington (e.g. at Bledington Pit [SP 248 233]) the more or less limestone-poor gravels overlie limestone-rich gravels. The latter are probably merely the lower, less decalcified parts of the deposit but may be the older Spelsbury Gravel Member (SPBY) (Arkell, 1947a, b; Horton et al., 1987), implying a crossing of the terrace profiles.
Definition of Upper Boundary: none recorded or not applicable
Thickness: none recorded or not applicable
Geographical Limits: Upper reaches of the Evenlode.
Parent Unit: Upper Thames Valley Formation (UTMS)
Previous Name(s): none recorded or not applicable
Alternative Name(s): none recorded or not applicable
