... ; Hughes et al. 1991 ; Fleet et al. 2000 ). The site preference for La is strongly related to the chemical composition of apatite. In an X-ray study of a synthetic lanthanum calcium silicate apatite Ca 4 La 6 (SiO 4 ) 6 (OH) 2 (space group P 6 3 / m ), Cockbain and Smith (1967) concluded that the La...

... appears to be determined by the mineralogy of their respective host carbonatites. At both localities, the REE minerals in fenite are less enriched in lanthanum and cerium than their equivalents in carbonatite, a characteristic that we attribute to REE fractionation within fluids in the aureole...

...(OH) 2 -La(OH) 3 at 100 MPa, but lanthanum hydroxide was the only La crystalline phase found in the run products. Wyllie et al. (1996) briefly mentioned that they had observed co-crystallization of calcite and hydroxybastnäsite from La-rich carbonatite melt in the system CaCO 3 -Ca(OH) 2 -La(CO 3...

...) that reported on the unit-cell dimensions of Ln OF phases, including CeOF. Therein, the authors state that “All the oxyfluorides examined with the exception of cerium oxyfluoride had the rhombohedral structure found by Zachariasen (1951) for lanthanum oxyfluoride. The cubic cell dimensions found for cerium...
