Paleomagnetic constraints on a time-stratigraphic framework for the evolution of Ohachidaira volcano and the summit caldera, central Hokkaido, Japan

We present a revised stratigraphy of the proximal deposits around Ohachidaira volcano and their paleomagnetic directions obtained from 21 sites (193 samples). We identify four proximal pyroclastic members from Ohachidaira volcano that were produced after the early edifice-building effusive volcanism...
