研究区包括北海道海岛隆起和千岛山系。本区的新构造已被许多研究者探讨过，但有关其新构造和动力地质学概念尚其说不一。对于在其研究工作中火山作用具有优先地位的大千岛海脊尤其如此。根据某些研究工作者的资料，千岛的现代地形从晚上新世末期已开始形成。但是也有人认...
The study area includes the Hokkaido island uplift and the Qiandao mountain system. The new structure of this area has been discussed by many researchers, but the concepts of neotectonics and dynamical geology are not the same. This is especially true for the Dajiandao ridge, which has a priority in volcanism in its research work. According to some researchers, the modern topography of the Thousand Island has begun to take shape from the late Pleistocene. But others also admit ...
