摘　　要：本研究采用便携式能量色散型X射线荧光光谱仪(pXRF)对湖北荆州熊家冢墓地出土的东周玉器进行了无损科技分析。结果表明:熊家冢墓地出土玉器的玉料具有多样性,根据玉器的用途和出土地点的不同,在用料和制作精细程度上都有区别;通过与相应玉石的理论化学组成相比较并结合少数样品的拉曼光谱分析结果,可以确定殉葬墓出土的装饰用玉如璜、璧、珩、管、牌等大都采用透闪石为原料,个别玉珩是用石英质原料制作而成;而马身上的玉饰片均以玉材质量相对较差的白云母为原料制作而成;此外还发现有水晶管、珠等器物。研究结果为深入认识熊家冢墓地出土玉器提供了基础科学依据,也充分体现了便携式分析设备在古代硅酸盐质文物的科技研究与保护中的作用。Non-destructive unearthed from the Xiongjiazh analysis with pXRF has been carried out ong Tombs in Jingzhou,Hubei Province. for the Eastern Zhou jade artifacts The results provide the following information： the jade artifacts are diversified; their materials and craftsmanship vary with their functions and buried sites; and by comparing them with relevant jade stones in chemical components and combining the IKaman spectroscopy analysis of a few samples, it can be confirmed that most of the decorative jade artifacts unearthed from the sacrificial tombs were made of tremolite. The research results not only provide a scientific basis for thoroughly understanding the jade artifacts unearthed from the Xiongjiazhong Tombs,but also completely exhibit the role of the portable analysis equipment in the research and preservation of silicate cultural relics.
