Unconformably overlies Westkapelle Ground Formation; passes laterally westwards into Smith's Knoll Formation. |
| Definition of Upper Boundary: |
Unconformably overlain by Winterton Shoal or Yarmouth Roads Formation or locally by Eem Formation in Dutch sector. |
| Thickness: |
0 - 200 metres, occurs only east of 2 deg. 40' East. |
