江西靖安东周墓出土玉器的玉质特征研究

ade Composition of Archaic Jade Artifacts from Eastern

为配合江西省文物考古研究所的出土文物研究,运用宝玉石学、岩石学和物理谱学的理论与资料,采用肉眼观察、宝石显微镜、红外吸收光谱(反射法)、激光拉曼光谱(散射法)、X射线衍射法和环境扫描电子显微镜等无损测试方法对江西靖安李洲坳东周墓的13件出土玉器样品进行了玉质特征鉴定。结果显示,有11件出土玉器样品为透闪石质软玉,2件出土玉器样品为粉砂岩类岩石。同时,还揭示了11件透闪石质软玉玉器的外观特征差异与其玉石成分和质地结构的关系。

In this paper,the jade compositions of thirteen archaic jade artifacts excavatedfrom the Eastern Zhou Tomb in Jing＇an,Jiangxi Province were,in terms of gemmology,petrology and physical spectroscopy,identified by means of naked-eye observation,gemmological microscope,IR spectrometer,laser Raman microspectrometer,XRD and SEM. This research is a project designated by Archaeological Institute of Jiangxi Province. The eleven archaic jade artifacts are composed largely of tremolite-nephrite,but the remaining two,of tiny sandstone. In addition,this paper also reveals the relationship between the surface characteristics and the compositions and structures of these eleven tremolite-nephrite archaic jade artifacts.
