Lithology and environment
| Primary lithology: | gray unlithified calcareous claystone |
| Environment: | offshore |
| Geology comments: The lower 2 m of the PCF are well exposed and include laminated mudstone and claystone with dispersed glauconite and foraminifera and centimeter-diameter, glauconite-filled, horizontal burrows. The lower part of the PCF is overlain by a 2–3 m interval of discontinuous iron oxide concretions. Above the concretion zone, the upper PCF is massive mudstone in medium to thick beds. (Larsen et al. 2015) | |
