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.

这项研究代表了一种尝试通过比较它们的硫同位素，32s和34s的比例来确定从Yayoi时代到Kofun时代的古代日本墓穴中发现的朱红色墓穴的来源。我试图解决四个主题，如下所示； （1）硫同位素的比率是否取决于每个朱砂矿？ （2）从现代矿山收集的二氧化碳矿石的硫同位素比与从古代矿山收集的矿石相似的比率？ （3）是否可以测量痕量朱红色的硫同位素？ （4）在古代墓穴中使用了人造朱红色？当测量了日本和中国不同矿山的豆制矿石矿石同位素的比率时，中国和日本矿石之间的比率明显不同。中国矿山中的朱砂矿石的比例显示出正值，日本矿山的比率显示为负值。并且在一个矿山中没有发现差异（在西部画廊的深度分别为-1.5‰和-1.1‰，在30 m的深度和-1.2‰和-1.5‰的深度和-1.5‰的深度中，在东部画廊的深度相同的深度）。因此，我认为从深处获得的矿石的数据代表了古代人从同一矿山收集的矿石。接下来，我试图测量痕量朱红色的硫同位素，发现2 mg和更多的朱红色的量可以测量。将人造朱红色的硫同位素与天然朱红色的比率进行比较时，它们之间没有差异。然后，我试图测量人造和天然朱红色的汞同位素。但是，获得的数据还不够。可能需要测量汞同位素的特殊仪器。
