Agglutinated quartz-siliceous foraminifera are widely spread in West Siberian, at least in Canadian and Middle Asia provinces. Considerable amounts of these forms are assigned to the rift structures which stretch out in the meridional direction in these provinces. The foraminifera assemblages of these forms may have been formed in the Arctic basin. As an example, we have studied agglutinated foraminifera of the Cenomanian-Turonian in the provinces along the rift to which industrial hydrocarbon field is assigned. The Plates 1-4—Cenomanian-Turonian agglutinated foraminifera of West-Siberian provinces are presented. Correlation of Foraminiferal zones and layers of West Siberian and Canadian provinces, showing the agglutinated index-species foraminifera are presented.
