In response to subsidence during the Miocene, the Sanriku-Oki forearc basin transitioned from a shelved and benched type forearc basin to a slope type forearc basin (Takano, ; Takano et al. Central Hokkaido has been a site of vigorous tectonic events throughout the Cenozoic reflecting the long-standing subduction of oceanic plates in the region. Ando H: Stratigraphic correlation of Upper Cretaceous to Paleocene forearc basin sediments in Northeast Japan: cyclic sedimentation and basin evolution. The total basin‐. The basin-forming process along a convergent margin off the eastern coast of Eurasia was pursued on the basis of geological, geochemical, and geophysical approaches.
