The Cretaceous sediments of Hokkaido are composed of miogeosynclinal and deltaic sediments from the Aptian to the Maastrichtian, distributed in two belts westward of the paired metamorphic belts. The ammonite fauna belongs to the Pacific- Tethyan realm and is dominated by off-shore forms. Correlation with the European standard by ammonites, inocerami, foraminifers, radiolarians and nannoplankton has been undertaken concurrently in the three districts. -from Author
