| 摘 要： | 近两年,我国珠宝市场上出现了大量的"西安绿""丹东绿"等绿色印材,其多被用来仿冒绿色寿山石("月尾绿"),并以高价售卖。采用X射线粉末衍射仪,电感耦合等离子质谱仪,扫描电子显微镜等测试仪器,对"西安绿""丹东绿"的矿物组成、化学成分以及微观结构进行分析,并与寿山"月尾绿"的宝石矿物学特征进行了对比。结果表明,"月尾绿"主要由铬云母组成,Cr,Fe元素是其呈浅绿色并略带灰黄色调的主要原因之一;"西安绿"主要由伊利石组成,其Cr,V元素的质量分数远高于"月尾绿"中的,且前者几乎不含Fe元素,这可能是其呈艳丽绿色的主要原因;"丹东绿"主要由斜绿泥石组成,Fe元素的质量分数较高且几乎不含Cr元素,致使其呈现较深的暗绿色。扫描电子显微镜的观察结果发现,与"月尾绿"相比,"西安绿"中伊利石的片晶厚、粒度小,"丹东绿"中斜绿泥石的片晶薄、堆积紧密,挠性发育。这三种绿色印章石在绿色色调、光泽、密度、内含物等方面存在不少的差异,可作为其鉴别特征。

| Abstract: | Xi'anlv and Dandonglv are used as the imitations of green larderite(Yueweilv) in the jewelry market recently.Mineral components,chemical compositions and microstructures of Xi'anlv and Dandonglv are investigated by using the XRD,ICP-MS and SEM,which are also compared with Yueweilv.The results show that Yueweilv is mainly composed of fuchsite,where the Cr and Fe elements lead to a slightly gray-green tone in colour;that Xi'anlv is mainly composed of illite with much lower Fe,and the content of elements Cr an... |
