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 bed C near base of section. | |||||
