In recent years, there have been significant advancements in the field of isotope analysis. Particularly, the emergence of a new generation of multi- collector inductively coupled plasma- mass spectrometry (MC- ICP- MS) testing technology has greatly contributed to its widespread application. As a result, non- traditional isotopes (eg, Cu, Sn and Ag isotopes) have demonstrated promising potential in tracing ancient metal products. This study aims to review and list below the progress made in the past two decades regarding the application of these isotopes in the research of ancient metal products, as well as their application prospects. ① The extensive and significant overlap of Cu, Sn, and Ag isotopes among different deposits makes it challenging to trace the geological source of metal products using these isotopes as independent evidence. ② Cu isotopes exhibit significant fractionation between primary and supergene ores, making them reliable for tracing copper ore types. Additionally, Ag isotopes have the potential to identify silver ore types. ③ By combining Cu- Sn- Ag isotopes with Pb isotopes and trace elements, comprehensive traceability research can be conducted using appropriate statistical methods. This integrated approach is expected to be the future direction for tracing ancient metal products using non- traditional isotopes.
