.... Overlying carbonate deposits of the Kotodzha Formation containing alumino-siliciclastics and chert interlayers are interpreted as the fore-reef slope and reef-foot facies. Deposition by turbidity currents is further observed upsection (Raiga Formation). A fine-grained texture of the Churbiga and Paidugina...

Coeval formations were distinguished: the Oksym Formation, in the Vostok-4 well; the Churbiga Formation (lower part), in the Vostok-3 well; the Lisitsa Series (volcanosedimentary part of the Lower Cambrian section in the Vezdekhodnaya area), in the Vezdekhodnaya-4...

... decreases considerably. The coeval sediments of the Usolka and Oksym Formations are here correlated with the lower unit of the Churbiga Formation (Vostok-1 and Vostok-3). The age correlation with the western parts of the Siberian Platform and western part of the Yenisei Ridge is similar to that of the above...
