宝鸡益门出土金柄铁剑镶嵌宝石的化学与矿物学特性

用扫描电子显微镜（SEM）及所配备的能谱仪（EDS）、X－射线衍射仪（XRD）对出土的三块宝石的化学及矿物学性质进行了分析研究，结果表明，其中两块宝石为金柄剑镶嵌宝石，其化学组成为绿松石，另一块宝石并非来自铁剑镶嵌物，具有正长石和钙长石的衍射谱图特征；绿松石加工制作过程曾使用了青铜工具进行表面打磨处理，说明我国在春秋时期已经开始使用青铜打磨工具。

Chemical and mineralogical characterization of some precious stone set in the golden handle of an iron sword excavated in a tomb of Yimen village, Baoji, China

Three pieces of precious stones set in the gold handle of an iron sword,excavated in a tomb of Yimen village, Baoji, China,were studied by using a scanning electron microscope with an equipped analytical system,and an X - ray diffrac-tometer, in order to define the chemical and mineralogical composition. The results show that two pieces of stones is clearly set in the iron sword of golden handle, of which the composition is turquoise. The other one is not from the iron sword of golden handle, which have the chart feature of orthocalse and anorthite.The bronze tools were used to make the surface of turquoise smoolh. It is stated that the bronze tools used in polishing process for the jade surface were probably started dur-ing the Spring and Autumn period in China.
