| Research Abstract |
The provenance study of bronze objects using scientific method became more important in archaeological science for the understanding of historical bronze culture development. Chemical composition and lead isotope ratio measurements were applied for this purpose to many of bronze samples. Bronze objects of Chinese Spring and Autumn, and Warring State periods were selected for this work from the viewpoint of East Asian cultural development. Samples were accumulated from Tokyo National Museum, Equine Museum of Japan, Xinjiang Archaeological Institute and others for this work. Bronze objects of the ancient peoples who lived in the northern part of China, so called Ordos and others were included in this work. Some of Xiajiadian samples were also included. Several topics obtained in this work were summarized as follows : 1) Xiajiadian samples showed varieties in chemical composition for different species. However, lead isotope ratios were rather concentrated in one value suggesting one source or the related bronze source. 2) The chemical composition suggests several features for different species. For instance, Knives and some blades contain rather high tin and low lead, high leaded bronze was used for vessels, and arsenic and iron concentrations are rather low but the changes in concentrations seemed to be related not only to the source of copper mines but also the level of smelting technique of copper. 3) Cauldrons in Xinjiang showed a large difference in shape and figures were found to be a variety of chemical compositions.
