Paleomagnetic evidence of the rotation of central Japan and the paleoposition of Japan.
Abstract Paleomagnetic studies of the Daishoji, the Echigo-Yuzawa and the Kataimogawa areas revealed complex intrablock tectonic rotations in the Central Honshu block which is sandwiched in between the Southwest and Northeast Honshu blocks. Paleogeographic maps of 16, 15 and 14 Ma are reconstructed by using paleomagnetic declinations obtained so far in Japan.
