在日本列岛西南部的南琉球群岛的白穗-Saonetabaru（SRS）洞穴遗址中挖掘出的距今约10，000年的古代陶器碎片是东海南部岛屿地区使用陶器的最古老的例子，包括北方和南琉球群岛，台湾和菲律宾。然而，由于其条件的限制，文化的延续性以及与下一个时期或其他地区的关系尚未得到阐明。在本研究中，我们使用X射线荧光显微镜对白穗Saonetabaru洞穴遗址的典型陶片进行了化学分析。尽管由于碎片化而难以分析其可见特性，并且由于其稀缺性而无法进行化学分析和样品破坏，但我们的方法使我们能够解开其糊状物的元素特征，尽管只有非常小的样品无法被破坏。我们还将这些最古老的陶片与同一地区的下一个时期的陶片进行了比较，结果表明，最古老的陶片与后来的陶片不同，这表明该地区首次使用陶器的时间过渡的新模式。这项研究代表了一种新的方法来确定最古老的陶片在东海南部地区，也提供了一个新的解决方案，如何处理较小的陶瓷碎片，是相对罕见的问题。
Ancient potsherds dating to about 10,000 years BP excavated in the Shiraho-Saonetabaru (SRS) cave site in the Southern Ryukyu Islands in the southwestern part of Japan archipelago are the oldest example of pottery usage in the island region of the southern East China Sea, including the Northern and Southern Ryukyu Islands, Taiwan, and the Philippines. However, their cultural continuity and relationship with the following period or with any other regions have not been elucidated as their condition made analysis extremely difficult.In this study, we conducted a chemical analysis of typical potsherds from the Shiraho-Saonetabaru cave site using an X-Ray fluorescence microscope. Although analyzing their visible peculiarities was difficult because of fragmentation and chemical analysis with sample destruction was impossible because of their scarcity value, our method enabled us to unravel the elemental characteristics of their paste despite possessing only very small samples that could not be destroyed. We also compared these oldest potsherds with those of the following period in the same region using statistical multivariate analysis; the results showed that the oldest potsherds differed from the later ones, suggesting a new model of chronological transition for the first pottery usage in this region. This study represents a novel approach to identifying the oldest potsherds in the southern East China Sea region, and also provides a new solution to the problem of what to do with smaller ceramic fragments that are relatively rare.
