— Dimlington Stadial (QDD) |
| Lithological Description: |
Compact matrix-supported diamicton with numerous subrounded, striated boulder-sized clasts. Clast lithology is dominated by the local andesite but there are also striated clasts of sandstones and other sedimentary rocks which have been brought from the south and west of the Kale Water (Mitchell, 2005, 2008). |
| Definition of Lower Boundary: |
Unconformable on bedrock. |
| Definition of Upper Boundary: |
This diamicton is at surface or is overlain either by re-sedimented diamicton which can be defined as a solifluctate (head) or by gravel. |
| Thickness: |
At least 3 m. |
| Geographical Limits: |
Valley of the Kale Water, Cheviot Hills. |
| Parent Unit: |
Cheviot Glacigenic Subgroup (CHVG)

| Type Section |
East bank of the Kale Water, south of Swanlaws: at least 3 m of highly compact diamicton with large subangular to subrounded erratic clasts of sandstone and fine-grained igneous rock (Mitchell, 2005, 2008). |
