Stratigraphy
| Formation: | Qom | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Qom Fm, which overlies the continental Lower Red Fm. THICKNESS: Unknown thickness. AGE: Qom Fm is Late Chattian-Early Miocene at this section (Mandic et al. 1997), and is here assigned an Early Miocene age based on interpretation of faunal ranges in Harzhauser (2004). STRATIGRAPHIC POSITION: From unknown position within unit, probably near top. | |||||
