Rare metal Nb-Ta-Zr deposit connected with leucogranitic massif.
This deposit (Grechishchev and others, 1997) is hosted in the Ulug-Tanzek pluton composed of main phase of subalkaline biotite granite, quartz syenite, granosyenite, and alkaline granite, and younger felsite and quartz porphyry with anomalous Li, F, Zr, and REE. Quartz-albite-microcline metasomatite with uniform low-grade REE replaces mainly the main phase. The pluton forms an inclined lenticular body that is enclosed by marble that dips moderately the southwest. The pluton is 1900 m long, ranges from 100 to 900 m wide, and extends to a depth of 700 m with no sign of wedging out.
