摘要

Ba-REE fluorcarbonate minerals from a carbonatite dyke at Bayan Obo, Inner Mon- golia, North China, are first reported in this contribution, in which chemical composition, rare earth element(REE)patterns, and intergrowth relationships for these minerals have been in- vestigated. Syntactic intergrwoth or syntaxy between cebaite and cordylite, as well as cordylite and huanghoite were observed. This syntactic texture resulted from the variation of chemical composition of crystallizing agents for those minerals that crystallized directly from carbonatite magmas.
