定边郝滩东汉壁画墓绿色底层颜料分析研究

Study of green ground layer in an Eastern Han Dynasty tomb mural painting at Haotan,Dingbian county,Shaanxi province

本研究以定边郝滩东汉壁画墓中绿色底层为研究对象,采用偏光显微镜(PLM)、带能谱的扫描电子显微镜(SEM/EDS)、X射线衍射仪(XRD)和拉曼光谱(RS)分析了绿色底层的成分与物相,同时和四种已知国外绿土相比较,得出绿色底色为绿土,对其进行深入分析研究以期为考古学和后期文物保护工作提供科学信息。

The green ground layer in an Eastern Han Dynasty tomb mural painting at Haotan,Dingbian was analyzed.Polarized light microscopy（PLM）,Raman spectroscopy（RS）,X-ray diffraction spectroscopy（XRD） and scanning electron microscopy-energy dispersive spectrometer（SEM-EDS） were used to analyzed the chemical and chase composition of the green layer.The results were compared with data of four European green earth samples.It was concluded that the green layer is green earth.However,further research is needed to provide more scientific information for archaeological and future conservation studies.
