| Research Abstract |
Paleomagnetic measurements were conducted on Miocene sedimentary rocks from central Honshu. Samples were collected from the Ichishi (Mie Pref.), Morozaki (Aichi Pref.) and Tomikusa (Nagano Pref.) groups, and the paleomagnetic directions determined for these groups were statistically analyzed in order to evaluate the crustal deformation caused by collision between central Honshu and the Izu-Ogasawara arc. Based on a paleomagnetic orocline test, it is concluded that the curved Median Tectonic Line in central Honshu, the most prominent fault in Japan, was straight 18-17 million years ago.
