- Аннотация: The results of study of the isotopic–lithological compositions of carbonate and terrigenous–carbonate rocks in the Soyana River section (northern East European Platform, Arkhangel’sk district) are presented. The results make it possible to identify 10 main lithotypes and show a wide variation range of d.13C(from –2.2 to +3.6‰, PDB) and d.18O (from 22.5 to 30.5‰,SMOW). These lithological features and isotopic compositions suggest that the rocks were formed in a shallowmarine setting characterized by rapidly changing sedimentation conditions in various facies (and/or paleoecological) zones: inlets, lagoons, supralit toral, littoral, and shoals. Periods of aridization and humidization are recorded. The results also indicate numerous synsedimentary shortterm hiatuses and stages of increased continental runoff episodic pulsatory input of clastic material with the continental paleoflows.
