- 要約等The stratigraphic ......undary between the Cretaceous and Tertiary formations in Amakusa and its adjacent areas is restudied t......ugh both field and laboratory works. The paleontological and lithostratigra...... revealed that the unconformity separating the two systems re......resents a time-interval of variable exten......lace to place. The studies of geological structures and petrography of sandstone indicate that a r...... clear changes in source rocks and environments occurred in the age represented by the unconformity and that the Paleogene sediments were accumulated in the tectonic depre......ions formed by the movement.
