中文摘要:
      采用偏光薄片观察、X射线粉晶衍射仪、扫描电镜/能谱分析等测试方法对浙江青田县青田石进行了研究,结果表明,所选青田石样品中的封门黄、黄金耀、灯光冻、红花冻4个品种的主要矿物成分为叶蜡石;封门黑、紫檀冻这两个品种主要由叶蜡石和绢云母组成;蓝星、猪油冻、酱油冻这3个品种的主要组成矿物为叶蜡石和伊利石;珍珠冻的主要组成矿物是红柱石和叶蜡石;山炮绿的主要组成矿物为绢云母.
英文摘要:
      Qingtian Stone from Qiantian County of Zhejiang Province is one of the famous “four seal stones" in China. Using such means as thin-section analysis, XRD and SEM/EDX, the authors systematically studied chemical composition and mineral composition of some typical species of Qingtian Stone. Some conclusions have been reached: ① Minerals of the selected samples are mainly composed of microscaly aggregates. ② Four types of Qingtian Stones, namely Fengmenhuang, Huangjinyao, Dengguangdong and Honghuadong, are almost exclusively composed of pyrophyllite, with Honghuadong stone also containing a small amount of ilmenite. ③ Fengmenhei and Zitandong stones are mainly comprised of pyrophyllite and sericite; in addition, Fengmenhei stone also contains a small amount of ilmenite, whereas Zitandong stone also contains hematite. ④ Lanxing, Zhuyoudong and Jiangyoudong stones are composed of pyrophyllite and illite, with Lanxing stone also containing a little illite and cryptocrystalline quartz, and Zhuyoudong stone also containing hematite. ⑤ Zhenzhudong stone is almost exclusively composed of andalusite and pyrophyllite. ⑥ Shanpaolü stone is mainly made up of sericite.
