| 中文摘要 | Five new polytypes of parisite-(Ce) [CaCe2(CO3)(3)F-2] from a rare-carth-mineral deposit within an aegirine-bearing granite pluton in Sichuan Province, southwestern China, were found by HRTEM: 6R(2), 8H, 14H, 36R and 42R. These new polytypes are all long-period ordered stacking structures, which may result from the distribution and the periodic variation in orientation of [CO3] groups between the unit layers of parisite-(Ce). The observed microstructures may be affected by the rock-forming environment. These new polytypes coexist with the very common polytype 6R(1), disordered stacking series. and mixed-layer structures developed in the host polytype, 6R(1). |
