Stratigraphy
| Geological group: | Kurnub | Formation: | Helez |
| Local section: | Lower Sand | Local bed: | 1611 m |
| Local order: | top to bottom |
Lithology and environment
| Primary lithology: | lithified sandstone |
| Secondary lithology: | ferruginous lithified carbonaceous "shale" |
| Environment: | marine indet. |
| Geology comments: The sediments of the Kurnub Group consist of shallow marine to continental sandstones, carbonaceous shales, sandy and ferruginous limestones, and marls. The lowest formation, the Zeweira, is the most arenaceous unit and includes the carbonaceous shales and lignitic layers that yielded the spores and pollen used in this study. The middle part of the Zeweira Formation contains the lowest marine intercalations
