抄録

In the middle part of the "Fossa Magna", the basement rocks of SW Japan and of NE Japan are in syntaxis. The geologic history of the Kirigamine and the Arafune areas, which lie at the apex of the syntaxis and situate in intimate relation with the two NE-SW trending "green tuff" areas in the Northern "Fossa Magna" zone, is summarized with special reference to the volcanisms during Pliocene and Quaternary. On the basis of geologic history, geologic structure and petrography, it is concluded that the present areas are geologically the eastern extension of the "Setouchi" province of SW Japan.
