Stratigraphy
Geological group:Nutov Formation:Nutovskaya
Stratigraphic resolution:formation
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the middle Nutovskaya suite of the "upper Nutov" horizon, which lies below the "Pomyr" (Pliocene) and above the "Okobykay" (Late Miocene) horizons. THICKNESS: Total thickness of unit is unknown. AGE: Pliocene, on the basis of classification into the "Pomyr" horizon. STRATIGRAPHIC POSITION: Composite checklist for middle part of the "formation" in this area.
Lithology and environment
Primary lithology:fine poorly lithified sandstone
Secondary lithology: poorly lithified claystone
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Ranges from fine-grained sand to gravel, with layers of limey sandstones, gravels, conglomerates and lignites. LITHIFICATION: Poorly-lithified, assumed on the basis of age and facies.
Environment:transition zone/lower shoreface
Geology comments: ENVIRONMENT: Not stated in text; assumed to be cool-water relatively shallow water coastal setting on the basis of faunal composition.
