公元前一千纪通往辽东山地的青铜物料流动

The Flow of Bronze Materials towards the Liaodong Mountainous Region in the Millennium B.C.

本文对辽宁本溪等地区出土东周青铜器进行了成分及铅同位素比值分析。在公元前六至前四世纪,本溪梁家M1多钮镜等器物与沈阳郑家洼子M6512出土青铜器均为铅锡青铜及铅锡砷青铜材质,铅同位素比值指示这些青铜物料与春秋早期的辽西山地存在关联。公元前三世纪,刘家哨和上堡出土青铜器均为铅锡青铜,使用的两类铅料分别与燕及三晋青铜器对应。自商周至战国早期,辽西山地一直是金属资源的缓冲地,汇聚中原和大井提供的不同类青铜物料,并在特定时段影响辽东及朝鲜半岛。战国中晚期以后,金属物料的流通枢纽逐渐东移,促进了辽东山地的社会发展,并推动以中原为中心的世界体系向东北亚地区扩张。

The composition and lead isotope ratios of the bro nzes during Eastern Zhou period unearthed front the Benxi region were analyzed.During 6~4 century BC,the mirror from Liangjia tomb M1 and other two axes are Pb-Sn bronze and Pb-Sn-As bronze,consistent with the bronzes front Zhengjiawazi tomb M6512.In the third century BC,the bronzes unearthed in Liujiashao and Shangbu are all Pb-Sn bronzes.The two types of lead materials are corresponded to the bronzes from Yan and Central plain respectively.Since Shang-Zhou period,the buffer zone of metal resources has been formed in western Liaoning,and the bronze materials of Central plain and Dajing have passed through the hilly land of western Liaoning and affected eastern Liaoning in certain period.After the middle and late Warring States period,the metal resource buffer zone was moved to eastern Liaoning,which promoted the social development of the Liaodong mountainous region as well as the expansion of the world system centered on the Central Plains to Northeast Asia.
