项目摘要

This study represents an attempt to determine the sources of vermillion found in ancient Japanese burial mounds from Yayoi era to Kofun era, by comparing their ratios of sulfur isotopes, 32S and 34S. I tried to resolve four subjects as follows ; (1)Does the ratio of sulfur isotopes depend on each cinnabar mine? (2)Is the ratio of sulfur isotopes of cinnabar ore collected from modern mine similar with the ratio of ore collected from ancient mine? (3)Is it possible to measure sulfur isotopes of trace vermillion? (4)Was the artificial vermillion used in ancient burial mounds?When the ratio of sulfur isotopes of cinnabar ore in different mines of Japan and China were measured, the ratios were clearly different between Chinese and Japanese ores. The ratio of cinnabar ore in Chinese mine showed positive values and the ratio in Japanese mine showed negative values. And no differences were found within one mine (-1.5 ‰ and -1.1 ‰ for depths of 30 and 90 m, respectively, in the west gallery, and -1.2 ‰ and -1.5 ‰ for the same depths in the east gallery). Therefore, I assume that data for ore obtained from deep locations are representative of the ores that ancient people gathered from the same mine. Next, I tried to measure sulfur isotopes of trace vermillion, and found that the amount of 2 mg and more vermillion could measure. When the ratio of sulfur isotopes in artificial vermillion was compared with the ratio in natural vermillion, there were no differences between them. Then, I tried to measure mercury isotopes in artificial and natural vermillion. However, the data obtained were not enough. The special instrument measuring mercury isotope may be needed.

本研究试图通过比较其硫同位素32S和34S的比值，确定弥生时代至古坟时代日本古代墓葬中朱砂的来源。我试图解决以下四个问题：(1)各朱砂矿的硫同位素比值是否不同？(2)现代朱砂矿石的硫同位素比值与古代朱砂矿石的硫同位素比值是否相似？(3)能否测定微量朱砂的硫同位素？(4)古代墓葬中是否使用了人工朱砂？对日、中两国不同矿区朱砂矿石硫同位素比值进行测定，发现中、日矿石硫同位素比值存在明显差异。中国朱砂矿的比值为正值，日本朱砂矿的比值为负值。同一矿山内无差异（西巷道30和90 m深度分别为-1.5‰和-1.1‰，东巷道相同深度分别为-1.2‰和-1.5‰）。因此，我假设从深部获得的矿石数据代表了古人从同一矿山采集的矿石。接下来，我尝试测量痕量朱砂的硫同位素，发现2毫克及以上的朱砂量都可以测量。人工朱砂中硫同位素的比值与天然朱砂中硫同位素的比值比较，两者之间没有差异。然后，我尝试测量人造朱砂和天然朱砂中的汞同位素。然而，获得的数据是不够的。可能需要专门的测量汞同位素的仪器。
