Compositional evolution and immiscibility processes in fractionated felsic magmas and its implications on Nb-Ta-Sn mineralisation KU Leuven
Rare-element pegmatites host high concentrations of gems, industrial minerals and strategic metals. The determination of the composition of pegmatite magmas remains one of the most challenging problems in the fields of petrology and metallogeny. During cooling of these magmas, crystals precipitate and the remaining melt enriches in elements that are unsuitable to get incorporated in the major mineral phases (e.g. Li, Nb, Ta, Sn etc.).
