Geographic resolution:outcrop
Time
Period:Neogene Epoch:Miocene
10 m.y. bin:Cenozoic 5
Key time interval:Early/Lower Miocene
Age range of interval:23.03000 - 15.98000 m.y. ago
Stratigraphy
Geological group:Hafún Formation:Ghibirti
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Ghibirti Fm [enterers usage] of the Hafún Series [group?] of Early Miocene, and presumably regionally overlies the Tavo Fm [enterers usage] (Late Oligocene) and is overlain by the Naag Fm [enterers usage] (Early Miocene). THICKNESS: Difficult to ascertain, but a bed of not great thickness. AGE: Early Miocene, equivalent to Aquitanian and lower Gaj according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From Bed C, near middle of section.
