|Сomplex justification of marine stratigraphical scales; forming the laptev sea cenozoic sequence as an example|
|The attempt of creating the complex stratigraphical base of a sedimentary cover is shown on an example of forming the Cenozoic sequence of the Laptev Sea. Due to the absence of marine drilling sequences, its major components are the marker levels of seismic profiles dated in accordance with the absolute geochronology scale; lithostratigraphical complexes established on seismic data and results of studying the Cenozoic formations of the onshore and adjoining offshore areas; biostratigraphic scale created on the materials of key sequences and including spore-pollen complexes and microfaunistical zones proposed in the Laptev shelf sequence. Chronologically dated markers LSI-3 and three event-biostratigraphical levels are the key correlative levels
Key words: stratigraphy, biostratigraphical scale, Cenozoic, sedimentary cover, Laptev Sea shelf
