• Translated from Russia [Valanginian of Kacha river basins and Bodrak presented in full. So far in this area are set both substage and the majority of ammonite zones allocated to stratotipiche skom region. Lower Valanginian area begins from here Kilianella otopeta. Onaobrazovana pack "pudingovyh" conglomerates and grits. Thickness of the zone of 1.5 m.

•Deposition zone Thurmanniceras pertransiens occur with little erosion and

•represented by the same species as the previous zone. Was sliced at it has a capacity

•of about 2.5 m. The rocks are encountered ammonites Thurmanniceras pertransiens,

•T. salientinum, T. ex gr. thurmanni, T. valdrumensis, T. geymardi, Bodrakiceras

•inostranzewi, B. moutonianus complex and other fauna, close the previous zone. The

•roof area is the surface of the "hard bottom."

•Zone Campylotoxia campylotoxa installed only in the state redeposited in the context

•of p. Kacha. Ammonites, demonstrating the presence of a zone, occur in low-power

•condensing the horizon, which consists of non-displaced fragments of the destroyed

•hard bottom. Horizon thickness of condensation, in which co-occur and fauna zones

•campylotoxa submartini, is 0.1-0.2 m.

•Zone Himantoceras trinodosum established based on findings Himantoceras cf.

•trinodosum only in the section was sliced in which it is composed of rhythmically

•alternating gray calcareous sandstones (0.2-0.3 m) containing phosphorite nodules

•and markazitovye and silty clays and pure bioturbirovannymi. Power packs of 6

•meters.

•Zone is represented by interbedded Teschenites callidiscus dense calcareous

•sandstones (0.2-0.3 m) and clayey sandstones, unconsolidated bioturbirovannyh Gray

•(1-2 m), containing dense calcareous concretions, con-

•Cretu marcasite, phosphates and large remains of fossil wood. Power

•NOSTA area of about 16 m.

•Zone Eleniceras tauricum, finishing Valanginian sequence is represented by an

•alternation of brownish-gray loose and dense slaboglinistyh carbonate sandstones

•containing weathered markazitovye nodules. Thickness of the zone on the southern

•slope of 17.5 m.]
