Abstract
Magnetostratigraphic studies on the Middle and Late Pleistocene deposits in Japan are summarized. It is emphasized that the identified records of geomagnetic excursion as well as reversal in sedimentary sections are useful evidence for time-correlation and chronology of the Pleistocene sections.Three VGP paths during the Matuyama-Brunhes transition defined in Japan are compared with each other. These paths are laid in the sector of longitude between 70°E and 120°E, and it is considered that the main dipole field decayed and standing part of the nondipole field predominated during the polarity transition. The comparison of several VGP paths recorded in the Neogene and Pleistocene sections in the southern Tohoku indicates that it is possible to distinguish the individual excursion or reversal from others by its characteristic features of VGP path.
