成都金沙遗址出土圆角方孔形铜器研究

Research on the Round-Cornered Square-Hole Ritual Bronzes from the Jinsha Site in Chengdu

通过对金沙遗址祭祀区出土的15件圆角方孔形铜器的形制特征、合金成分和金相组织的分析,认为圆角方孔形铜器的用途应为祭祀中的礼仪用器,其形制与合金成分具有一定的相关性,锡铅比越小,矩形度越大。金沙遗址出土的圆角方孔形铜器与三星堆文化有着密切的联系,本文研究的15件圆角方孔形铜器应为三星堆文化与十二桥文化过渡时期的产物。

Based on the analysis of the shape characteristics,alloy composition and metallographic structure of 15 round-cornered square-hole bronzes unearthed in the sacrificial area of Jinsha Site,it is considered that the application of roundcornered square-hole bronze should be a ceremonial device in sacrifice,and there is a certain correlation between the shape and alloy composition,the smaller of the Sn/Pb,the greater of the squareness.The round-cornered square-hole bronze is closely tied to the Sanxingdui culture,The round-cornered square-hole bronzes in this study should be product of the transitional period between Sanxingdui Culture and Shierqiao Culture.
