Syenitic migmatites of the contact of the Ilmenogorsky miaskite block are characterized by high (>500 ppm) contents of REEs, which are mainly hosted in fuorapatite and titanite of the leucosome. Apatite exhibits zoned and sectorial composition with decreasing REE and Si contents and increasing Cа, P, and F contents from central parts to the margins indicating the change in physicochemical conditions of mineral formation. The La/Nd ratios of REE-bearing fuorapatite indicate that apatite-1 formed from a F-bearing fuid in contrast to apatite-2 formed from an alkaline, F–CO2–SO3-rich fuid during albitization. The REEs and F released by alkaline metasomatism accumulated in late generation of REE–F-bearing titanite. Migmatization of rocks was accompanied by involvement of an alkaline F–CO2–SO3-bearing fuid.
