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

分析了韩国出土的青铜、镀金青铜、银和方铅矿在2~7℃的铅同位素比值，并与日本皇室、东京大学(出土于Naklang)、长野市和日本历史国立博物馆的青铜进行了比较。分析样本总数为240个。结果，我们发现了两个组，命名为A和B，许多数据集中在这两个组上。A组与Kinki-San‘en型Dotaku用标准化材料制作的数据吻合较好。A组的年代为公元前2世纪至公元4世纪。相应地，B组的数据具有一定的分散性，但该组由143件朝鲜青铜器的43件样品，34件皇室器物的13件样品和6件NMJH青铜器的5件样品组成，因此这是材料的主要地区之一。A组的起源被估计为北部中国。根据前人的铅同位素分析结果，认为B组的物质来源为中国南部，但与B组非常接近的奇尔戈克矿的资料和地质情况表明，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.
