九连墩楚墓出土璧玉、石磬和镶嵌物的科学分析

Scientific Analysis on Jasper,Chime Stone and Embedded Object Excavated from Jiuliandun Chu Tomb

本文采用X射线衍射技术和X射线荧光分析技术对九连墩楚墓出土的璧玉、石磬和镶嵌物进行了物相分析和成分分析。结果表明璧玉的主要成分为透闪石,石磬的主要成分为方解石。同时对镶嵌物的分析表明当时可能采用的是红铜镶嵌技术。这次分析为九连墩出土文物的复仿制和进一步的保护工作提供了科学依据。

Phase and composition of the jasper, chime stone and embedded object excavated from Jiuliandun Chu Tomb was analyzed with methods of X-Ray Diffraction Technology and X-Ray Fluor- escence Spectrometric Analytical Technology.. The results suggest that the main composition of jasper and chime stone are tremolite and calcite, respectively, whereas the rose copper embedding technology was adopted at that time. The study offers scientific foundations for deplicating, modeling and conserv- ing these cultural relics.
