Outline of Final Research Achievements |
1. We elucidated the distribution status and archaeological, petrological characteristics of Takada rhyolites (siliceous tuff), which are regional lithic raw materials distributed mainly in Hiroshima Pref. and the archaeological and petrological characteristics of the stone tools used the same one. And we clarified part of the procurement and management of regional lithic raw materials. We conducted the lithic raw material distribution survey on the Akitsu block around Saijo Basinand the Takada block around Miyoshi Basin. As a result of, we clarified that the lithic raw materials source was extremely ubiquitous and small-scale, and that the Horayama area in Akitsu block is a strong candidat as lithic raw marerials source. 2. We investigated that the status of regional and wide-area lithic raw materials at Paleolithic sites in the Chugoku region was clarified by period, and elucidated the concrete aspect of the use of lithic raw materials which change from former to latter.

Academic Significance and Societal Importance of the Research Achievements |
旧石器時代の石材研究は黒曜石、サヌカイトなど広域石材を主体に実施され、地域石材の研究はほとんど行われてこなかった。本研究は地域石材の一つである広島県を中心に分布する高田流紋岩類を中心に、考古学的、岩石学的に解明し、その研究成果は旧石器時代の石材獲得・運用を、地域石材、広域石材の両面から考察することを可能にした。地域集団の形成や変遷をより具体的に明らかにすることができるようになるとともに、今後の研究のモデルケースとなった。石材研究を通じて旧石器時代史をより具体的に明らかにできるようになった意義は大きい。
