| Lithological Description: |
The Nordelph Peat contains trunks and roots of oaks and small trees, some in situ, and woody debris from alder, birch, sallow, buckthorn and pine are common. In the more seaward areas the peat is largely composed of stems and rhizomes of sedges and reeds. In southern Fenland the peat contains thin but extensive, lenticular deposits of shell marl which formed in shallow meres within the peat fens. |
| Definition of Lower Boundary: |
Rests on a variety of earlier typically non-peat Holocene and older glacigenic deposits. Change of lithology across junction very discernable. |
| Definition of Upper Boundary: |
Overlain by the Terrington Beds in many places, elsewhere at surface. |
| Thickness: |
Generally less than 1 m, but locally up to over 3 m where preserved in channels. |
| Geographical Limits: |
Restricted to the area of Fenland. |
