Stratigraphy
| Formation: | Bayan Mandahu |
| Stratigraphic resolution: | bed |
Lithology and environment
| Primary lithology: | sandstone |
| Includes fossils? | Y |
| Environment: | dune |
| Geology comments: The sediments at Bayan Mandahu consist of fine sands, mudstones and caliches. These sediments are interpreted as being deposited between a mountain range and an active dune field (Eberth 1993; Jerzykiewicz et al. 1993), by streams, ponds and dunes. Overall, the facies closely resemble those found at Bayn Dzak | |
