10 m.y. bin: | Cenozoic 4 |
| Key time interval: | Early Oligocene |
| Age range of interval: | 33.9 - 27.3 m.y. ago |
| Geological group: | Hafún |
Formation: | Gheldeis |
| Stratigraphic resolution: | group of beds |
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Gheldeis Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies Late Eocene strata and is overlain by the Gianti Fm [enterers usage] (Early Oligocene). AGE: Early Oligocene, equivalent to Stampien and middle Nari according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within section. |
