Multilateral Comparative Study on Introduction, Acculturation and Distribution of Bronze Culture in East Asia

我们分析了朝鲜南部2 - 7 ℃的青铜、镀金青铜、银和方铅矿的铅同位素比值，并与日本宫内厅、东京大学（Naklang出土）、长野市和国立日本历史博物馆的青铜器数据进行了比较。分析的样本总数为240。结果我们发现了两个组，命名为A和B，其中许多数据集中。A组的数据与用标准化材料制作的近畿三恩型Dotaku的数据符合得很好。A组的年代为公元前2 ~ 4世纪，B组的资料有一定的分散性，其中包括143件朝鲜青铜器中的43件、34件宫内厅青铜器中的13件和6件新明宫青铜器中的5件。A组种源估计为中国北方。以往的铅同位素分析结果认为B组物质来源于中国南方，但与B组物质非常接近的漆谷矿区的资料和地质环境指出B组物质来源于朝鲜半岛半岛南部的可能性。

We analyzed lead isotope ratios of bronze, gilded bronze, silver and galena ezcavated from southern Korea in 2 to 7C., and compared the data with those of bronze belonging to the Imperial Household Agency, Tokyo University (excavated from Naklang), Nagano-city and National Museum of Japanese History. The total number of analyzed samples was 240. As a result we found out 2 groups, named A and B, at which many data were concentrated. The data of group-A were well accorded with those of Kinki-San'en type Dotaku, which were made with standardized materials. The age of objects belonging to group-A was from B.C.2C to 4C.A.D. Correspondingly, The data of group-B were dispersive in some degree, however, the group consisted of 43 samples from 143 Korean bronzes, 13 samples from 34 the Imperial Household Agency objects and 5 samples from 6 NMJH bronzes, so it was supposed to be one of the main area of materials.The provenance of group-A was estimated to be northern China. That of group-B was, from the results of former study of lead isotope analysis, thought to be southern China, but the data of Chilgok mine, which came very close to group-B and geological circumstances pointed out the possibility that the provenance of materials of group-B was southern area in Korean peninsula.
