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:15.97000 - 11.60800 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 M near top of section.
