| Lithological Description: |
The Flugga Sandstone Member consists of clean, very fine to medium sandstone displaying distinctive 'blocky' log profiles. Thin intercalations of dark grey, fissile mudstone are also present. |
| Definition of Lower Boundary: |
The base of the Flugga Sandstone Member is taken at a downward change from sandstone to mudstone, associated with an increase in gamma-ray values and decrease in velocity. Where the Skadan Sandstone Member is present, the two sandstone units are normally separated by the persistent S2a mudstone (refer to Sele Formation). |
| Definition of Upper Boundary: |
The top of the Flugga Sandstone Member is taken at a downward change from mudstone to sandstone, associated with a decrease in gamma-ray values and, in some sections, an increase in velocity. |
| Thickness: |
Reaches more than 270 m thick in 16/1-1. |
| Geographical Limits: |
The Flugga Sandstone Member is restricted to South Viking Graben, largely in the UK sector, but probably extending into Norwegian Block 15/5. It occurs in a north-south belt immediately to the east of the Dornoch Formation. |
