This paper presents the results of biostratigraphic investigations of cherty and terrigenous deposits from the Taukha Terrane. Twelve successive radiolarian assemblages which correspond to the upper Pliensbachian-lower Toarcian, lower-middle Toarcian, upper Toarcian-middle Aalenian, upper Aalenian-lower Bajocian, middle Bajocian, upper Bajocian-lower Bathonian, middle Bathonian-lower Callovian, middle Oxfordian-lower Kimmeridgian, middle-upper Kimmeridgian, lower-middle Tithonian, upper Tithonian, and lower Valanginian-lower Barremian deposits of the continuous section have been distinguished. Characteristics of the radiolarian assemblages are shortly given.
