| Lithological Description: |
Silt and sand containing pollen, plant macrofossils, coleopteran, molluscan, ostracod and mammalian evidence of deposition under temperate conditions. The fauna and flora suggest deposition in a warm temperate climate in an environment ranging from estuarine through salt marsh to fluviatile or possibly ponded.The silt and sand interdigitate with gravel. To the west of the type site, the Woodston Member is overlain by gravels mapped as the third terrace of the River Nene. |
| Definition of Lower Boundary: |
Probably unconformable on the Lowestoft Formation. |
| Definition of Upper Boundary: |
The deposit occurs beneath the Third Terrace of the River Nene from Orton Waterville eastwards for about 3 km. |
| Thickness: |
Up to 3 m. |
| Geographical Limits: |
