Stratigraphy
Geological group:Hafún Formation:Gargorre
Stratigraphic resolution:group of beds
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Gargorre Fm [enterers usage] of the Hafún Series [group?], and presumably regionally overlies the Naag Fm [enterers usage] (Early Miocene) and is overlain by the Late Miocene conglomerates. AGE: Middle Miocene, equivalent to Burdigalian-Helvetian and uppermost Gaj/lower Mekran according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within section.
