The interpretation of the data of a seismic profile grid in the territory of the East Siberian Sea is performed. Four seismic complexes in the section of the sedimentary cover are distinguished: Aptian-Albian (synrift), Upper Cretaceous (synrift), Paleocene-Eocene (postrift) and Oligocene-Quaternary (postrift). In the East Siberian Sea two rift phases have been discovered: the Aptian-Albian main phase and the Late Cretaceous additional phase. The rifting conditions were later replaced by transpression that had preceded the formation of a regional unconformity horizon dated by the Cretaceous-Paleogene boundary. The clinoform complexes that formed of sediments that were transported from the east are recorded over the regional unconformity boundary in the complex of the Paleocene-Eocene postrift deposits.
