摘要
和田玉属软玉类玉石 ,是透闪石矿物的集合体 ,也可称透闪石玉。白玉、青白玉和青玉是和田玉的主要品种。经电子探针分析 ,和田白玉、青白玉和青玉基本上由透闪石组成 ;透闪石主要由SiO2 、MgO和CaO组成 ,含少量Al2 O3、FeO、TiO2 和MnO。玉石颜色主要与Fe2 +、Ti4+、Mn2 +的含量有关 ;具致密块状构造 ,扫描电子显微镜下显示毡毯状和显微交织结构 ,部分可见到显微粒状结构。
Hetian jade, also called tremolite jade, is one kind of nephrite, it is aggregation of tremolite mineral. White jade, grey\|white jade and grey jade are major species of Hetian jade. According to electron microprobe analysis, the major species are mainly composed of tremolite, in which the main chemical components are SiO 2, MgO and CaO, with minor components of Al 2O 3, FeO, TiO 2 and MnO, some impurity minerals are found in Hetian jade. The color of jade is mainly related to the content of Fe 2+ , Ti 4+ and Mn 2+ . Macroscopically, Hetian jade has compact massive structure, under the scanning electron microscope, felty texture, interlocking micro\|texture and granular micro\|texture can be observed.
