| Lithology description: "Sharply asymmetric cyclite; in the lower and middle parts of the stratum there is a rhythmic alteration of members, consisting of brown, yellow-brown limestones, fine-grained, and quartz, massive or with a spherical jointing and in the form of a "facet roadway", transferring upwards to yellow-brown, massive silststones. The thickness of separate members is up to 3.0-3.5 m. The upper part of the layer is formed by green siltstones with rare interbeds of brownish siltstones or with white carbonate joints. These layers contain fish scales, conchostraci and ostracods. The total thickness is over 26 m." | |
