Lithology and environment
| Primary lithology: | "limestone" |
| Secondary lithology: | marl |
| Lithology description: "[Isheevo Formation - Crimson Shale Member] Packages 07/110 - P07/125 Interval 58.45 - 66.85 Thickness 8.40m Alternation of limestone, marl and shale with subordinate interbeds of siltstone and sandstone. Limestone is light- or dark-grey, muddy, compact, solid, algal-microbial, sometimes very hard and finely wavy laminated, riddled with numerous voids of plant roots in situ. Shale: bright red, bright green, greenish-grey, calcareous. Shale with lenticular lamination contains numerous remains of ostracods, bivalves, fish scales and tetrapods. Shale with greenish-grey and red spots (stains) of gleisation is overfilled with calcareous concretions (paleosol horizons). The Tobacco Sandstone Member, which overlies the Crimson Shale Member, is observed at outcrop P09 (Collection no. 197590)." (Nurgaliev et al. 2015) | |
