| Abstract: | 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. |
