A Quantitative Study for Distribution of Pottery Containing Typical Mineral Particle from Jomon Period to Kofun Period

本研究是对含有典型颗粒角闪石的陶器分布变化的研究。在弥合和高峰期，含角闪石陶器的分布在山体周围受到限制。大阪和奈良县的伊科玛。但对柔门期的分布还没有进行定量的研究。我们对含绳陶的角闪石的分布进行了定量研究，结果表明，这些分布比弥合时期和古方时期的分布范围更广。角闪石陶器的出现率与距伊科马山的距离无关。这一事实表明，有一些地方生产的粘土或矿物颗粒含有角闪石。我们清点了含有闪石的陶器数量，清水用偏光显微镜观察检查了一些陶器。观察结果表明，我们的计数是正确的，尽管我们计数的角闪石中有一些陶器含有辉石。

This study is a study for changes of distributions of pottery containing typical particle Amphibole. In Yayoi and Kofun period, the distributions of Amphibole contained pottery are restricted around Mt. Ikoma in Osaka and Nara Prefectures. But the distributions in Jomon period have not been studied quantitatively. We studied the distributions of Amphibole contained Jomon pottery quantitatively, and showed that those were broader than of Yayoi and Kofun period. The rates of Amphibole contained pottery is not related with distances from Mt.Ikoma. This fact suggests that there were some places producing clay or mineral particles contained Amphibole. We counted numbers of pottery contained Amphibole, and Shimizu checked some pottery with observation by a polarizing microscope. The result of observation showed our counting was correct, though some pottery we counted Amphibole contained were containing pyroxene.
