- •
Zr-REE mineralization in the sodic lujavrite from the Saima complex is first reported.
- •
Differences in Zr-REE mineralization between the potassic nepheline syenite and sodic lujavrite are compared.
- •
High peralkalinity, Na/K ratio, HFSE content, low oxygen fugacity, and high activities of water and volatiles are responsible for the Zr-REE mineralization.
