Clastic roks of the Sablya ridge (Subpolar Ural)

We have confirmed the development of three coarse layers with different genesis and stratigraphic affinity in the northern part of Sablya Ridge (Subpolar Urals): intraformational volcanogenic sediments of sablegorskaya (RF3–V1sb) formation, laptopayskaya (V2–Є1lp) volcanogenic sedimentary molasse, shallow water marine terrigenous rocks of telposskaya (O1tl) formation. The reconstruction of sedimentation conditions was made and the model of development at the transition stage from epicontinental riftogenesis to passive margin was suggested. We used typochemical features of monazite as the diagnosis attribute together with traditional petrographic, geochemical and mineralogical criteria.
Key words: conglomerates, gravelites, tufogravelites, sandstones, clastic rocks, uralides, preuralides.
