首次在白云鄂博碳酸岩岩墙中发现了氟碳铈矿和氟碳钙铈矿等稀土氟碳酸盐矿物 ,并运用偏光显微镜、阴极发光、扫描电子显微镜和电子探针等手段对其进行了观察和分析 .研究表明 ,氟碳铈矿很少呈单一均匀晶体存在 ,多含有氟碳钙铈矿微细客晶 ,沿 (0 0 1)面网与其构成规则的共面网定向附生结构 (epitaxy) .氟碳钙铈矿也含有氟碳铈矿微细客晶 ,它们形成规则的面衍生结构 .这种面衍生结构是矿物因结晶介质的化学成分变化所引起的 ,是从碳酸岩浆中直接结晶过程中所形成的
For the first time, rare earth fluorocarbon minerals, such as bastnaesite and bastnaesite, were found in the Bayan Obo carbonate rock dikes and were characterized by polarized light microscopy, cathodoluminescence, scanning electron microscopy and electron probe The results show that bastnaesite is rarely present as a single uniform crystal and contains many fine guest crystals of bastnaesite along the (0 0 1) plane network and its regular coplanar network structure ( The bastnaesite also contains fine bastnasites of bastnaesite, which form a regular surface-derived structure that is caused by the change of the chemical composition of the mineral due to the crystallization medium, directly from the magmatic magma Formed during crystallization
