| Research Abstract |
Sourcing of the stone implements and the ornaments and beads were accomplished by using XRF and electron spin resonance by non-destructive. The Horonaikawa group was made from the obsidian found on the Okushiri island. The Sakamoto group was made from the andesite found in Tottori Prefecture recently, and the Sakamoto group was used for the stone implement of the Hiruzen archaeological site. Moreover, the stone implement of a stone material uncertain mine was excavated in this archaeological site. The relic group was made from data which analyzed this stone implement 30 times or more. Recently, investigated stone material group and relic group are newly added to former old stone material group. And, obsidian is increased to 208 groups and the number of andesites has increased to 108 groups respectively. The oldest obsidian relic in Japan of ago of about 30,000 years which had been excavated in the Nojiri lake archaeological site was identified with the obsidian of Aomori Prefecture away at about 480 km. The obsidian of Kosidake was carried to Okinawa Prefecture away in the age of Jomon at about 750 km. It searched for the stone material mine of Mesirominami-B group of the sourcing of jasper ornaments and beads but it was not possible to find it. The number of the stone material group and relic group of jasper has increased to 22 groups in total. The jade of Itoigawa spread to an Okinawa Prefecture chyatan-cho away in the age of Jomon at about 1600 km. The thickness of the hydrated layer of about 250 obsidian stone implements was measured by the method of non-destructive. The hydrated layers were found to be the first time thickness of the obsidian stone implements in the paleolith age of Oki island in Japan to be 4.5-5 micrometers.
