The discriminating of production sites of ancient pottery samples using multi-isotopic systematics was described. Previous work has proven that Pb isotopic ratios can be used for discriminating the production sites of ancient pottery under certain conditions. The present work suggests that although Nd isotopic ratios are not sensitive to the production sites of ancient pottery

Sr isotopic ratios are important for the purpose. Pb isotopic ratios are indis- tinguishable for the pottery excavated from the Jiahu relict

Wuyang

Henan Province and for famous Qin Terra-cotta Figures. But

the 87Sr/86Sr ratios for the former (about 0.715) are significantly lower than that of the latter (0.717—0.718). We concluded that a combined use of Pb and Sr isotopes would be a more powerful method for dis- criminating the production site of ancient pottery.
