The Monchetundra massif is loed in the northeastern Fennoscandian Shield and refers to Paleoproterozoic massifs of the EastScandinavian Large Igneous Province. The general section of the massif comprises two parts, the lower noriteorthopyroxenite and the upper mafic zones. The lower zone is of great interest due to its associated industrial platinum group elements (PGE) mineralization.

Analytical and crystallographic data suggest a complete solidsolution between zircon and pretulite. Xenotime(Y), also epitactic on zircon, shows distinct stages of crystallization, with a decrease in Y together with an enrichment in the lighter REE and Sc (up to wt.% Sc 2O 3). The scandium minerals at SaintAubin reflect the evolution of the iron ore, from sedimentation to diagenesis and ...
