钙－铈氟碳酸盐系列矿物各成员之间的体衍交生现象非常发育，极易形成有序－无序混层结构及多型体等。Ｂ３Ｓ２＝ＢＢＳＢＳ即为该矿物系列中的两个端员矿物氟碳铈矿（Ｂ）与直氟碳钙铈矿（Ｓ）结构单元层以３∶２沿ｃ轴方向的有序堆垛而成。Ｊ．Ｖ．Ｌａｎｄｕｙｔ［１９...
The phenomena of somatization between members of the calcium-cerium fluorocarbon series minerals are very well developed, and it is easy to form an ordered-disordered mixed-layer structure and polytype. B3S2 = BBSBS is the order of 3: 2 along the c-axis direction for the two endmember mineral bastnaesite (B) and orthocarbonate cerium (S) structural unit layers in the mineral series . J. V. Landuyt [19 ...
