MAGNETOSTRATIGRAPHY OF UPPER CRETACEOUS SEDIMENTS OF SOUTH OM’ BASIN (WEST SIBERIAN PLATE)
Magnetobiostratigraphic data on the Upper Cretaceous sediments stripped by 3 wells in the southern side of the Om’ basin (southern West Siberia) were obtain. Magnetobiostratigraphic regional section of the Upper Cretaceous sediments was compiled on the basis of comprehensive data. This section comprises five Upper Cretaceous regional horizons and same-named formations, which have not been studied paleomagnetically at all in West Siberia. The generated regional magnetobiostratigraphic section consists of three magnetozones, one of them - normal polarity and two another - reversal polarity.
