Chemical variability of eudialyte-group minerals and their sorting

Bulakh, Andrei G.; Petrov, Tomas G.

Abstract

Only 57 analyses of eudialyte minerals of 308 probes of the world collection have a total of results more 97.5 %. 56 of them can be sortet into following chemical sets: CaFe (28 samples), CaMn (18), CaSr (2), CaNb (1), MnCa (7). A minor element Nb presents in eudialyte-group minerals of any composition, while W is established only in probes of CaSr set.
