| 1 | Epitaxy of rare earth element fluorcarbonate minerals from carbonatite dyke at Bayan Obo, Inner Mongolia, China显示文摘Rare earth element fluorocarbonate minerals such as bastnaesite and parisite are firstly discovered in carbonatite dykes from Bayan Obo, Inner Mongolia, China. Bastnaesite rarely occurs as homogeneously single crystal, but contains microfine phase of parisite. They form regular intergrowth along (0001) plane net, which is identified as epitaxy. This eptactic texture results from the variation of chemical composition of crystallizing agents of those minerals that crystallize directly from carbonatite magma. | Xueming Yang Peishan Zhang Kejie Tao Xiaoyong Yang Shuangxi Chen Minglong Zou M.
