Geography
| Country: | Iran |
| Coordinates: | 33.0° North, 52.1° East (view map) |
| Paleocoordinates: | 32.1° North, 51.2° East |
| Basis of coordinate: | stated in text |
| Geographic resolution: | outcrop |
Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Aquitanian - Burdigalian | ||
| Age range of interval: | 23.03000 - 15.98000 m.y. ago |
Stratigraphy
| Formation: | Qom | ||||
| Stratigraphy comments: Because of the lack of diagnostic fossils the biostratigraphic zonation of this section is less precise and gives an Early Miocene age only. |
Lithology and environment
| Primary lithology: | marl |
| Secondary lithology: | "limestone" |
| Lithology description: The lower part of the Zefre Section is dominated by marls. It is topped by a limestone dominated sequence.[...] The branches of these colonies are horizontally arranged forming sheetstones. | |
| Environment: | shallow subtidal indet. |
| Geology comments: Corallites are partly present on both sides of the branches indicating shallow, well-illuminated water. [...] One horizon in a marly section with laminar Leptoseris colonies is interpreted to be a deeper-water environment. | |
Taphonomy
| Modes of preservation: | recrystallized |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | very poor |
Collection methods and comments
| Collection methods: | field collection |
| Reason for describing collection: | paleoecologic analysis |
