Lithology and environment
Primary lithology:shelly/skeletal,gray,green marl
Includes fossils?Y
Lithology description: "Occurs in greenish-gray, nodular marls and lenses and thin laminae of limestones which west of Rataichitsy 12 are replaced by more argillaceous strate (homogeneous marls)..." [Coquinas]
Environment:marine indet.
Geology comments: "Occurs in greenish-gray, nodular marls and lenses and thin laminae of limestones which west of Rataichitsy 12 are replaced by more argillaceous strate (homogeneous marls) in which shallower water benthos...decrease rapidly, and where in the Vyssokoue 1 Borehole the fauna is chiefly graptolitic...[fauna and lithology] provide evidence for shallow water conditions...Also important is an organogenic buildup in the eastern part of the region. During Russilov time there was transgression in the basin. Presence of Skenidioides consistent with BA 5."
