项目摘要

This research project focuses on the settlement patterns and lithic resource environment of the Palaeolithicin the middle of the Shinano river with particular interests of the Mattobara site. Location A, B, and C are essential three parts of this site, and they all located on the Late Pleistocene terrace of Shinano river. Archaeological characteristics of the artifact assemblage are various forms of small Point tools, gravers, and scrapers. Location A and C encamped exactly the same period which were verified with four refitted lithic flakes. Major lithic material comprises of siliceous hard shale, siliceous tuff, and glassy textured andesite. Obsidian is available but very small amount.In these two years, we have excavated at Location B supported by this project fund, in order to elucidate the character of this location. In view of lithic artifact assemblage and characteristic features of Point tools, location A, C, and B are belonging to the same period typologically as well as geologic stratigraphy. On the contrary, lithic use at location B is differ widely. Dominant material is shale and with no obsidian at all. Geologic sources of obsidian and siliceous hard shale are distant from the site nearly a hundred kilometer. In this context, if the shale was obtainable near by Mattobara site, two different human migration area may possible to set out, in conjunction with lithic resource procurement. This project has also reconstructed the Shinano river bed in the same age of Mattobara site.

本研究项目重点研究信野河中段古石器的聚落模式和岩质资源环境，特别是松原遗址。位置A、B和C是遗址的三个重要部分，它们都位于信野河晚更新世阶地上。文物组合的考古学特征是各种形式的小点工具、雕刻器和刮刀。地点A和C的扎营时间完全相同，并用四片改装的石片进行了验证。主要岩性物质包括硅质硬质页岩、硅质凝灰岩和玻璃质地安山岩。在这两年里，我们在这个项目基金的支持下，在B地点进行了挖掘，以阐明这个地点的特征。从岩屑组合和点状工具的特征来看，A、C、B三个地点在类型和地质地层学上都属于同一时期。相反，在B位置使用石材差别很大。主要材料是页岩，根本不含黑铁矿。黑铁矿和硅质硬页岩的地质来源距离现场近百公里。在这种情况下，如果页岩是在松原遗址附近获得的，那么两个不同的人类迁徙地区可能就有可能出发，结合岩屑资源的采购。该项目还重建了与松原遗址相同时代的Shinano河床。
