Provenance of quartzite clasts from the Shimanto belt, southwest Japanese Islands (preliminary report)

The conglomerate including quartzite clasts occurs at various places in Japan. In this paper, the Muro and Nichinan clasts of the Shimanto belt were examined using optical and cathodoluminescence microscopes. Based on the paleogeography of Paleo-Japan before the opening of the Sea of Japan, it is concluded that these quartzite clasts were probably derived from the edge of East Asian continent.
