Ba-REE fluorcarbonate minerals from a carbonatite dyke at Bayan Obo, Inner Mongolia, 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 investigated. Syntactic intergrowth 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. It is worth noting that REE patterns of the Ba-REE fluorcarbonate
minerals in the dyke are similar to those of the corresponding minerals from the ore hosted dolomite marble of the Bayan Obo
giant REE-Nb-Fe mineral deposit, which implies their relation in origin. 相似文献
