... of fluorapatite in the space now occupied by the voids, combined with element remobilization from the body of the fluorapatite as a whole, provided the Ca and S needed for the formation of anhydrite as well as the P and LREE required for the enrichment of the bright areas. britholite fluorellestadite...

...V.V. Sharygin Abstract Three minerals of the mayenite supergroup have been found in fluorellestadite-bearing metacarbonate rock (former fragment of petrified wood of ankeritic composition) from the dump at the Baturinskaya-Vostochnaya-1-2 mine. These are eltyubyuite Ca 12 Fe 10 3+ Si 4 O 32 Cl 6...

... minerals (calcium uranates). The Ca-U(VI) oxides are associated with typical pyrometamorphic minerals, such as sulfate-bearing fluorapatite, fluorellestadite, spurrite, fluormayenite, dorrite, brownmillerite, srebrodolskite, periclase (Zn-, Ni-, Co-, and Cu-rich), lime, and U-rich lakargiite. The primary...

...” and “wilkeite”, respectively, by previous workers. “Ellestadite” is actually a solid solution involving the end-members Ca 10 (SiO 4 ) 3 (SO 4 ) 3 Z 2 , where Z = OH (hydroxylellestadite), F (fluorellestadite), or Cl (chlorellestadite). The term ellestadite is redefined to make it a group name for all...
