Аннотация: The Upper Jurassic–Lower Cretaceous sedimentary rocks in the Eastern BarentsSea Basin are up to 2 km thick and represent one of the least studied Arctic intervals.Here, for the first time, we present a detailed analysis of 43,000 km of 2Dseismic profiles, as well as well-logand core data from 24 offshore wells withthe aim to create a comprehensive sequence stratigraphic framework that canbe integrated with the rest of the basin. Results show that (1) seven third-ordersequences and five types of clinoforms can be identified based on integrated seismicand well data. The age of each sequence was established based on publishedbiostratigraphic investigations along with new dinocyst interpretations includedin this study; (2) the deep marine basin was gradually filled with sediments comingfrom north, east and south as a response to HALIP, Canada Basin openingand Cimmerian uplift of Novaya Zemlya, and was preserved only in the south-westernpart of the Barents Sea Basin at the end of Early Cretaceous and (3) bothEastern Barents Sea and West Siberia Basin share similarities in sedimentary environmentsand tectonic setting, though the spatial distribution of clastic reservoirsin Upper Jurassic and Lower Cretaceous mega-sequenceheavily dependson the source areas that require more provenance focused research. The resultspresented here can be used in further regional exploration in the area and to betterunderstand the geodynamic evolution of the Greater Barents Sea Basin.
