Geography
Country: | Somalia |
Coordinates: | 11.2° North, 49.0° East (view map) |
Paleocoordinates: | 10.8° North, 47.3° East |
Basis of coordinate: | based on nearby landmark |
Geographic resolution: | outcrop |
Time
Period: | Neogene | Epoch: | Miocene |
10 m.y. bin: | Cenozoic 5 | ||
Key time interval: | Middle Miocene | ||
Age range of interval: | 15.98000 - 11.63000 m.y. ago |
Stratigraphy
Geological group: | Guban | Formation: | Dubar | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Dubar Fm [enterers usage] of the Guban Series [group?], and presumably regionally overlies Early Miocene strata (equivalent to the Naag Fm) and is overlain by the Late Miocene conglomerate. AGE: Middle Miocene, equivalent to Helvacean and lowermost Mekran according to author on the basis of larger formaniferal and molluscan biostratigraphy. Ostrea virleti is indicator for this zone. STRATIGRAPHIC POSITION: From bed H near middle of section. |
