Abstract

Apatite-nepheline bodies in the Khibiny are spatially confined to an arc-shaped intrusion of ijolite-urtite. They are gently inclined to the center of the massif and occur in its hanging wall at the contact with rischorrites and medium-grained nepheline syenites. The shape of ore bodies is lenticular-stratiform, their thickness is from 10‑30 to 100‑150 m, and their dip to the center of the massif is 25‑50°. The largest among them – Kukisvumchorr‑Yuksporr and Rasvumchorr ore bodies – are located in the southwestern part of the arc-shaped band of ijolite-urtites and form the Southwestern ore field (S.M. Kirov, Yuksporr, Apatite Circus, Centralny mines). 15 km to the north of the ore field is the Kuelpor‑Lavoyok deposit, 5 km to the east is the Koashva ...
