采用结晶学模块法研究了黄河矿(CeBa(CO3)2F),中华铈矿(CeBa2(CO3)3F)和氟碳铈钡矿(Ce2Ba3(CO3)5F2)的晶体结构。三种矿物的晶体结构中存在五种相同的配位多面体及其单链。多面体链相互联接组成两种似层状模块(H)和(Z)。黄河矿和中华铈矿的晶体结构分别由似层状模块(H)和(Z)构筑而成,氟碳铈钡矿则由这两种模块的交替堆垛形成。根据多体模型三种矿物的结构可分别用(HH)、(Z)和(HZHZ)表示,(Z)和(H)模块均具有1/2b位移。借助多体模型可解释该系列矿物结构的堆垛无序和预测新多体矿物。
The crystal structure of CeBa (CO3) 2F, CeBa2 (CO3) 3F) and bastnaesite (Ce2Ba3 (CO3) 5F2) have been studied by means of crystallographic method. There are five identical coordination polyhedra and their single chains in the crystal structure of the three minerals. Polyhedron chains are interconnected to form two stratiform-like modules (H) and (Z). The crystal structure of the Yellow River and Cericium ore is constructed from stratified modules (H) and (Z), respectively, whereas bastnaesite is formed by alternating stacks of these two modules. According to the multi-body model, the structures of the three minerals can be represented by (HH), (Z) and (HZHZ) respectively, and the (Z) and (H) The multi-body model can be used to explain the stacking disorder and the prediction of new multi-body minerals in this series of mineral structures.
