项目摘要

In this study, I examined factors that lithologic characters influence to productions of stone implements. I performed experiments of stone implements making and compared it with stone artifacts excavated from archeological site due to resolution of this problem that I assumed. Particularly, a sanukite which circulated widely in western Japan in prehistoric age was a main analysis object.On the experiment, I used sanukite and obsidian, quartzite, chart as samples. At first, in the stage for detached large-sized flakes from raw materials, there were no clear differences in the flakes produced by the experiment between all rocks. However, as for sanukite, a direction of flaking was taken regulation to have fluxion structure. On the experiment used the divided raw material, obsidian cores showed that it was easy to detach elongate flakes from the core in succession. By contraries, sanukite cores are easy to detach wide flakes from the core in succession. This reason is because it is easy to control a percussion power by a soft hammer. Stone knapping are evidently influenced by the fluxion structure of sanukite. In the experiment of making stone points from core blanks, the stone points were manufactured by sanukite and chart were not different from obsidian points mutually. These reasons are because percussion angles are small and platforms are flat. Such a characteristic is different from a common view, and sanukite materials show that it was not disadvantageous for manufacturing of stone points.

在这项研究中，我考察了岩性特征对石器生产的影响因素。为了解决我所设想的这个问题，我进行了石器制作的实验，并将其与考古现场出土的石器进行了比较。特别是，在史前时期广泛分布于日本西部的三柳石是主要的分析对象。在实验中，我使用了sanukite和黑曜岩，石英岩，图表作为样本。首先，在从原料分离大尺寸薄片阶段，所有岩石在实验中产生的薄片没有明显的差异。而对于sanukite，则采取了剥落的方向进行调节，使其具有流动结构。对分离后的黑曜石岩心进行了实验，结果表明，黑曜石岩心很容易连续分离出细长的薄片。相反，三努基岩岩心很容易从岩心上连续分离出宽片。这是因为用软锤很容易控制打击力度。三努基岩的流体结构对击石有明显的影响。在用芯坯制作石点的实验中，石点是由桑努基岩制作的，图与黑曜石的石点没有相互差异。这些原因是因为冲击角度小，平台平整。这样的特点不同于一般的看法，而散流岩材料表明，它并不不利于制造石点。
