项目摘要

In1964, Pro. Chosuke Serizawa of Tohoku University excavated Sozudai Site, Ooita Pref., Southwestern Japan. Vie compared these stone implement groups with the East Asian materials in lower Paleolith and assumed that they had been made about 100,000 years ago. In this study, we re-excavated this site after an interval of 37 years, and obtained new materials from there.We compared them with the other Japanese materials which had been obtained 30,000 years ago based on chronological data and regional differenses.As aresult, the stone implement groups of Sozudai Site are divided into the 4 stages as follows. 1) The stone implement group of stage 1 excavated from the andesite gravel bed layer, and it is the oldest among the stone implement groups of Japan. This stage is seen after the forming of Shimosueyoshi terrace and the nearly age when deceding of Kuju-Shimosakataand Aso-4 Tephra This age might be 90,000 -110,000 years ago. 2) The stone implement group of stage 2 is similar to Hoshino Site after 60,000-70,000 years ago. 3) The stone implement group of stage 3 is similar to Kanetori Site about 50,000 years ago. 4) In the stage 4, the stone implement group is similar to Magano Site in the beginning of Late Paleolith. In the stage 2, the regional differences occured in the stone materials and the feature of stone implements.

1964年，Pro.东北大学的芹泽长介（Chosuke Serizawa）挖掘了大分县Sozudai遗址日本西南部。Vie将这些石器组与下古石器中的东亚材料进行了比较，并假设它们是在大约10万年前制造的。本研究在时隔37年后对该遗址进行了重新发掘，获得了新的材料，并与日本3万年前的其他材料进行了年代学和地域差异的比较，将该遗址的石器群体划分为以下4个阶段。1)第一阶段的石器组是从安山岩砾石层中挖掘出来的，是日本石器组中最古老的。这一阶段出现在下末吉阶地形成之后，与九州-下坂和阿索-4火山口消亡的年代相近，距今约9 ~ 11万年。2)第二阶段的石器群与6 - 7万年前的星野遗址相似。3)第三阶段的石器群与大约5万年前的金取遗址相似。4)第四阶段的石器群与晚古石器时代初期的马加诺遗址相似。第二阶段，在石器材料和石器特征上出现了地域差异。
