| 摘 要： | 运用透射电镜方法，在山东郗山稀土矿床的钙－铈氟碳酸盐系列矿物中发现了三方晶系直氟碳钙铈矿（ｓｙｎｃｈｙｓｉｔｅ）的存在，其晶胞参数为ａ＝０．７１２ｎｍ，ｃ＝５．６１６ｎｍ，衍射符号为３ｍＲ－ｃ－．通过与加拿大魁北克某矿区产出的单斜晶系的直氟碳钙铈矿的对比研究，确认本矿区产出的直氟碳钙铈矿为其同质二象变体．

| Abstract: | The synchysite with rhombohedral system has been discovered within the calcium-cerium fluorocarbonate of the rare-earth deposit of Chishan area in Shandong Province by using transmission electron microscope. Its unit cell parameters are a =0.712nm, c =5.616nm. The results compared with synchysite from Mont Saint-Hilaire, Quebec in Canada show that the rhombohedral synchysite and monocline ones are polymorphism. |

| Keywords: | synchysite rhombohedral system transmission electron microscope polymorphism Shandong Province |
