Abstract

The microstructural characteristics of syntactic polycrystal in the calcium-rare earth fluoro-carbonate minerals from Southwest China have been studied by means of selected area electron diffraction and high resolution electron microscopy (HREM). The complication of the heterogeneous fabric of the minerals have been revealed by HREM. The results show that the crystal structure of the minerals is formed by a disorder stacking of the unit layers of bast-naesite and synchisite in the calcium rare earth fluoro-carbonate minerals along c direction. The stacking fault and other crystal defects in the syntactic polycrystal are discussed.
