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

我们分析了韩国南部出土的2 - 7C的青铜、镀金青铜、银和方铅矿的铅同位素比率。并与宫内厅、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。分析样本总数为240个。结果我们发现了两个组，分别是a组和B组，很多数据都集中在这两个组。a组的数据与Kinki-San'en型Dotaku的数据吻合较好，均采用标准化材料制作。属于a组的物品的年龄从公元前2c到公元4ad。与之相对应的是，b组的数据较为分散，但该组由143件韩国青铜器的43件样品、34件宫内厅的13件样品和6件NMJH青铜器的5件样品组成，因此应该是主要的材料区域之一。a群的种源估计在中国北方。从以往的铅同位素分析研究结果来看，b组被认为是中国南方，但与b组非常接近的漆谷矿资料和地质环境表明，b组物质的来源可能是朝鲜半岛南部地区。

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.
