... 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...

... the rhombohedral structure found by Zachariasen (1951) for lanthanum oxyfluoride. The cubic cell dimensions found for cerium oxyfluoride are within the range of values reported by Finkelnburg and Stein (1950) who found that the cell constant of the fluorite-type structure varied with the amount of fluorine...

... variation. Lanthanum significantly prevails among REE in all analyses in the type specimen. The empirical formula calculated on the basis of 7 O atoms per formula unit is (La 1.02 Ce 0.86 Nd 0.08 Pr 0.04 ) Σ2.00 Si 2.00 O 7 . The idealised, end-member formula is La 2 Si 2 O 7 which requires La 2 O 3...
