Stratigraphy
Local section:Gorodische Local bed:Go 12-14
Stratigraphic resolution:group of beds
Stratigraphy comments: Go 12-14 - 0.20 m; Virgatus Zone; Middle Volgian, 'Traditionally, the Volgian was considered to be equivalent of the Tithonian stage. However, many data contradict these correlations (Sey and Kalacheva, 1993).'
Lithology and environment
Primary lithology: lithified "siliciclastic"
Lithology description: The Volgian formation is studied in the shore of the Kuibyshev Reservoir, between Gorodische and Dubky. The upper Volgian formation is also detailed at Kashpir, 4 km south of Syzran, on the Kuibyshev Reservoir. It corresponds to 18 m of terrigenous deposits, argillaceous in the lower part and sandy in the upper part, with intercalations of four major black shale horizons.
Environment:marine indet.
Taphonomy
Size of fossils:macrofossils
Collection methods and comments
Collection methods:field collection
Reason for describing collection:biostratigraphic analysis
