The results of palynological analysis of the sediments of the Abalak Formation from five boreholes in the Shaim petroleum-bearing region (northwestern part of Western Siberia) allow determining the Late Jurassic (Oxfordian to Volgian) age of the deposites in question. The study of taxonomic composition and stratigraphic distribution of dinoflagellate cyst as well as spores and pollen grains, acritarchs and prasinophyts have provided the basis for a local biostratigraphic subdivision of these deposits. The geosequence of five dinozones has been defined.
