| Local section: | Evtropiny Noski outcrop | Local bed: | Unit 5 | ||
| Local order: | bottom to top | ||||
| Stratigraphy comments: "Evtropiny Noski outcrop is about 330m in length and is formed by a simple, wide syncline, the eastern limb of which is faulted just to the east of the synclinal axis." | |||||
