| Lithological Description: |
A transported glacial raft of very strongly compressed, sheared and folded peat containing well preserved fragments of moss and high percentages of Hornbeam palynomorphs. Such values are typical of the later temperate stages of the Ipswichian Interglacial. |
| Definition of Lower Boundary: |
No lower boundary as such because field relationships confirm that the item is a glacial raft enclosed by dark grey stony diamicton of the Wear Till Formation. The peat is sheared, folded and streaked out towards the southwest in a similar direction to that indicated by the erratic content and fabric of the enclosing till. |
| Definition of Upper Boundary: |
No upper boundary as such because field relationships confirm that the item is a glacial raft enclosed by grey stony diamicton of the Wear Till Formation. The peat is sheared, folded and streaked out towards the southwest in a similar direction to that indicated by the erratic content and fabric of the enclosing till. |
