硫黄同位体分析による西日本日本海沿岸の弥生時代後期から古墳時代の墳墓における朱の産地同定の試み

抄録

Vermilion was collected from powerful people's mounds of places of Japan Sea coast depending on the period from the decline of the Yayoi to Kofun and was measured sulfur isotope ratio (δ³⁴S value), and compared the value obtained from cinnabar ores of three Japanese mines, Niu, Yamato-suigin, and Sui, and two Chinese mines, Wanshan and Xunyang, which were selected from old records. The vermilion of the late Yayoi period, the 1st to 2nd century A.D., was from China, and the vermilion of the early Kofun period, from the late 3rd century A.D., was from Japan. During the late Yayoi and early Kofun periods, the 3rd century A.D., the vermilion showed the middle of the shift of Japanese cinnabar. It is concluded that the measurement of sulfur isotope of vermilion is an effective method for the determination of original sources of vermilion.
