Stratigraphy
| Formation: | Mzamba | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: Probably from the onshore Mzamba Fm on the basis of faunal similarity. AGE: Middle Santonian to Early Campanian, on the basis of ammonite biostratigraphy. Assigned here to intermediate age of Late Santonian. STRATIGRAPHIC POSITION: From concretion exposed on seafloor surface. | |||||
Lithology and environment
| Primary lithology: | fine,ferruginous lithified "siliciclastic" |
| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Ferruginous internal molds. Traces of the fine-grained, ferruginous matrix adhere to some of the specimens. Unfortunately no other data on the lithology of the are are available. LITHIFICATION: Lithified, on the basis of facies description. | |
| Environment: | coastal indet. |
| Geology comments: ENVIRONMENT: Shallow marine siliciclastic setting. | |
