朝鲜半岛及日本细形青铜武器的原料产地

The places of raw materials of the slender bronze weapons in Korea Peninsula and Japan

对朝鲜半岛及日本出土细形青铜武器的原料产地问题作了尝试性探讨,以了解朝、日及中国大陆古代青铜原料的流通状况。利用青铜器及铅矿物中所含铅的四种稳定同位素的比值,在三维坐标系中观察其分布规律,并结合统计学方法探讨青铜器所含铅与铅矿地域特征的关联。通过比较分析中国大陆、朝鲜半岛及日本列岛出土的部分青铜器及铅矿物标本的铅同位素比值,指出上述三地某些青铜器原料中的铅可能有共同的产地,而朝、日当地铅矿的开采似不早于公元7世纪,故朝、日细形青铜武器的铅原料可能来自中国大陆。

The paper intends to discuss about the producing areas of raw materials used to make slender bronze weapons unearthed in Korean Peninsular and Japan, in order to understand the circulation of the ancient bronze raw materials among Korea, Japan and China's Mainland. The author used four kinds of steady lead isotope ratios in bronzes and lead minerals to find its distribution laws in a three- dimensional coordination. Furthermore, combined with statistics method, the paper analyzed the relation between the lead in bronzes and the features of places where lead mines located. Through the comparative analysis of the lead isotope taros in the samples of lead minerals and some bronze unearthed in China's Mainland, Korean Peninsular and Japan, the author pointed out that lead in some bronzes unearthed in the three places may come from the same prooducing area. However, the exploitation of lead mines in Korea and Japan astarted 7^th century later, so the lead in slender bronze weapons of Korea and Japan probably came from China's Mainland.
