中国、美国和日本学者对商代青铜器作了大量的铅同位素组成测定,结果发现这些商代遗址虽然彼此相距较远,但出土的青铜器的有关数据很多均具有一种罕见的高放射成因铅同位素组成特征[1];同时这种特殊的铅同位素组成特征的数据在商代以前未见以及商末以后时代的青铜器中出现不多〔2]。将不同时代青铜器铅同位素资料与中国大陆铅同位素省区划特征和目前开采的矿产资源铅同位素组成作比较,可以发现,
Chinese, American and Japanese scholars made a large amount of determination of lead isotopic composition of bronzes in Shang dynasty, and found that although these Shang dynasty ruins were far away from each other, many of the bronze wares unearthed had a rare high-yielding lead isotope Compositional characteristics [1]. At the same time, the data of this particular Pb isotopic composition have not appeared in bronze wares that have not been seen before in Shang and later Shang dynasties [2]. Comparing the bronze lead isotope data of different ages with the lead isotopic provinces of mainland China and the lead isotopic compositions of mineral resources currently being exploited,
