Stratigraphy
| Formation: | Ichetuy | ||||
| Stratigraphy comments: Formation also translated Ichetyua. Insect workers often assign a late Early Jurassic-early Middle Jurassic (or Toarcian-Aalenian) age but radiometric dating of Ichituy Fm volcanics gives ages of 159-156 Ma. |
Lithology and environment

| Environment: | lacustrine - small | Tectonic setting: | rift |
| Geology comments: Novospasskoe was a typical Mesozoic lake of type "A" according to Sinitshenkova and Zherikhin (1996), a deep mountain lake formed when a river valley was naturally dammed. It was a cold oligotrophic water body with low primary production and ample oxygen. | |||
