铜同位素分析法在考古研究中的应用探讨

Copper isotope analyses applied to archaeological studies:a review

最新地球化学研究发现,自然界不同地质条件和成矿环境中的铜同位素组成存在显著差异。根据铜矿中铜同位素变化规律,考古学家已将铜同位素作为一种新的示踪剂应用于考古探源研究之中。文章介绍了铜同位素地球化学的最新发展、考古应用原理、实验方法及相关的考古应用实例。认为尽管自然界铜同位素的变化较为复杂且铜同位素地球化学还处于形成发展阶段,但铜同位素分析法在含铜器物的产地研究中已显示出了较好的应用前景。随着铜同位素地球化学研究的深入及分析技术的进一步提高,铜同位素分析法将会在考古研究中发挥更大的作用。

Recent geochemistry researches show that significant variations in copper isotope composition occur in different geological and metallogenic environments. Because of the regularity of copper isotope variations in copper ore deposits,copper isotopes a new tracer that can be applied in archaeological provenance studies. This research briefly introduces the progress in copper isotope geochemistry, analytical technique for copper isotope analysis and their application to archaeology. Although copper isotope geochemistry is still in its formative stage and the variation of copper isotope in nature is very complicated, the application of copper isotope analyses to provenance studies of artifacts made from copper ore shows bright prospects. Copper isotope technique will play a more important role with the advance of copper isotope geochemistry and analytical techniques.
