MC-ICP-MS analysis is conducted on seven Han dynasty bronze artifacts from Liangshan Yi
Autonomous Prefecture Museum, Sichuan Province, Southwest China. The lead isotope ratios conform to
the characteristics of the common lead. The lead ore sources are mainly located in Mengzi-Gejiu and
Qiaojia-Huize area, Yunnan Province. Some lead ore was from Geochemical Province of Southern China.
A further study shows the lead ores used by Ba State in the Eastern Zhou dynasty (476 BC-221 BC) were
used in the Han dynasty (202 BC-221 AD). The lead ingot products were utilized in Liangshan bronze
industry. Moreover, in the Han dynasty, the ancient cultures of Liangshan, Dian, Ba and Yelang were
exchanged. By contrast, communications among Liangshan, Dian and Ba were closer.
