INTRODUCTIONBronze drum culture was well developed in China since more than 2500 years ago to 1828 A.D. Ancient drums are representatives of the historical culture of minority people living in southern China. The early drums, Wanjiaba and Shizhaishan types unearthed in Yunnan have been investigated by lead isotopes in this note. The scientific basis for the lead method was described in Refs. [2, 3] and the isotopic ratios were corrected with the NBS-981 standard shown in Table 1. Based on the experimental results, we would like展开更多

Some of the Lengshuichong type drums have abnormal Pb isotopic ratios, which means that they were made of special ore sources, one of the possibilities is that the ore material or the drums were transported from South- East Asia to Guangxi Province, because they have been excavated there too.展开更多
