Outline of Final Research Achievements |
Ore and slag samples from several mines and smelting sites in pre--modern Japan were analyzed by geo-scientific methods(chemical composition, mineral assemblage, texture and stable lead isotope). In case of the Iwami-ginzan silver mine, chemical compositions of ore and slag shows addition of extra lead to smelting process of silver ore. And also, data from Stable lead isotope analysis shows the origin of lead ore. These results will be useful for understanding of metal production process in Japan.
