摘要
针对三星堆遗址三号祭祀坑出土的青铜器物表面作为特征存在的浅蓝色粉末状锈蚀物,综合利用显微拉曼光谱仪与X射线荧光光谱仪等分析测试手段,在前人相关研究基础上,提出了新的认知与补充.研究结果显示:三星堆特征的浅蓝色粉状锈主要组成为非晶态Sn化合物掺杂有部分孔雀石与碳酸铅,浅蓝色粉状锈表面存在白色的白铅矿与磷氯铅矿.根据存在形式不同,浅蓝色粉状锈存在三种分层状态.其中磷氯铅矿的形成与三星堆遗址中埋藏的大量象牙存在关联.
Abstract
In view of the light blue powdery rust that appeared as a feature on the surface of the bronze artifacts excavated from Sanxingdui,a new understanding and supplement were proposed based on the analysis and testing method such as micro-Raman spectrometer and X-ray fluorescence spectrometer.The results show that the light blue powdery rust characteristic of Sanxingdui was mainly composed of malachite and amorphous Sn compounds,and there were lead carbonate and pyromorphite on the surface of the light blue powdery rust.There were three different layering states of light blue powdery rust depending on the form of presence.Among them,the formation of phosphate chloride lead ore was related to the large number of ivory buried in the Sanxingdui site.
