| 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. |
