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
Primary lithology: lithified "siliciclastic"
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.
