摘要：通过对贵州软玉和其他产地典型软玉的取样,采用光学显微镜、扫描电镜、XRD、WDXRF等手段对矿物组成、化学成分以及岩石矿物学特征进行研究。分析表明贵州软玉的矿物成分主要以透闪石为主,次要矿物成分为石英和方解石,此外还夹杂了少量类质同象替代物;而铁的混入是影响贵州软玉颜色的关键因素,与其他典型产地软玉类型有明显不同。
Through analyzing the chemical composition and characteristics of rock mineralogy of Guizhou nephrite and other typical ones by optical microscopy, scanning electron microscopy, XRD and WDXRF, the main mineral composition of Guizhou nephrite is tremolitite with the secondary mineral compositions of quartz and calcite. In addition to tremolitite as main composition, there is a small amount of isomorphous substitution; mixing of iron is a key factor to influence the color of Guizhou nephrite which is significantly different from other typical nephrites. These results provide a partial explanation to Guizhou nephrite apparent characteristics.
