Lithology and environment
Primary lithology: "shale"
Lithology description: "[Ufimian Stage, Sheshmian Formation (Horizon)] Package E1/1 Interval 0.0-0.4m Thickness (visible) 4.0m Sandstone: yellowish-bronw, polymict, greywacke, calcareous-muddy, fine-grained and medium-grained, cross-bedded, solid. Clastic grains: quartz (15-35%), local rocks (15-30%), effusive rocks (15-30%), and siliceous rocks (approx. 10%). Sporadic components (1-5%): potassium feldspar, biotite, plagioclase; clinochlore, muscovite, orthoclase. Most grains are coated with a film of iron hydroxides. Package E1/2 Interval 4.0-20.0m Thickness 16.0m Siltstone and shale: red, reddish-brown, pinkish-red, calcareous, with disorderly or massive structure and green spots of gleisation and calcareous concretions (1-50mm) (paleosol horizons). Clastic grains: quarts (70%), volcanic and chert rocks (25%), feldspar (2%), sporadic flakes of mica. The package contains thin (1-15cm) laminae of bluish-grey calcareous siltstones and greenish-grey fine-grained sandstone. Package E1/3 Interval 20.0-27.0m Thickness 7.0m Sandstone: yellowish-grey, polymict, fine-grained, cross-bedded, partly calcareous and solid. In the lower part, the sandstone contains lenses and pebbles of reddish-brown shales and siltstone. Clastic grains: volcanic rocks (70%), quartz (20%), feldspar (5%), biotite (5%). Grain size ranges from 0.1 to 0.5mm (predominantly 0.1-0.25mm). Package E1/4 Interval 27.0-32.0m Thickness 5.0m Siltstone and shale: reddish-brown, calcareous, with disorderly and massive structure and green spots of gleisation and calcareous concretions (1-30mm) (paleosol horizons). The lower part of the bed contains rare non-marine ostracods Palaeodarwinula sp. Package E1/5 Interval 32.0-34.5m Thickness 2.5m Sandstone: brownish-yellow, fine-grained, slightly argillaceous, greenish-grey at the top and at the bottom. Clastic grains: quartz (35%), feldspar (35%), effusive rocks (15%), and siliceous rocks (approx. 10%). Most grains are coated with a film of iron hydroxides. Package E1/6 Interval 34.5-42.5m Thickness 8.0m Alternation of reddish-brown and dull-brown unbedded mudrocks and siltstones with yellowish-brown sandstones. Shales are slightly calcareous, silty, with green spots of gleisation and calcareous concretions (1-30mm) (paleosol horizons). Clastic components (10%) are represented by subrounded, isometric and elongated grains of quartz (0.01-0.05mm). Siltstones are calcareous-argillaceous, sometimes with numerous calcareous nodules 0.5-1.0cm in diameter (paleosol horizons). Clastic components (0.05-0.2mm) contain angular, less subrounded grains of quartz (95%), rock fragments (3%), grains of feldspar and mica flakes. Sandstones are calcareous-argillaceous, polymict, fine-grained. Clastic components (75-80%) are represented mainly by the debris of shale rocks; rarely by modified grains of volcanic rocks, quartz and plagioclase. [Lower Kazanian Substage; Baitugan Beds; Lingula Shales Member] Package E1/7 Interval 42.5-50.5m Thickness 8.0m The transition between Ufimian and Kzanian is gradual. The lower part of the bed (ca. 1m) shows the thin alternation of grey and bright-red shales. These shales are overlain by grey, bluish-grey, thinly laminated, platy shales. Upwards in the section, these shales are overlain by grey, calcareous, regularly bedded siltstones and sandstones with thin (0.1m) lamina of limestone. The rock contains foraminifers, numerous inarticulate brachiopods, and also ostracods, bivalves and fish scales." (Nurgaliev et al. 2015)
