Includes fossils?Y
Lithology description: "Occurs in greenish-gray marls with lenses and laminae of marlstones (limestone and marl rhythmite)...(the brachiopods and bryozoans occur in both the marls and shaly limestones).
Environment:marine indet.
Geology comments: "...BA 4-5 (similar rocks and fossils occur in an equivalent position in the Furmanovka Formation in Podolia. To the west of the Rataichitsy 12 Borehole the limestones and marly rhythmites are replaced by argillitic marls, and in the Borstshovo 10 and Vyssokoye 1 Boreholes graptolites already dominate."
