Stratigraphy
| Geological group: | Guban | Formation: | Dubar | ||
| Stratigraphic resolution: | group of beds | ||||
| 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: Early Miocene, equivalent to Burdigalian and upper Gaj according to author on the basis of larger formaniferal and molluscan biostratigraphy. STRATIGRAPHIC POSITION: From unknown position within section. | |||||
