Tungsten-Bearing Wodginite from the Kester Deposit, Eastern Siberia, Russia

Li-F granites from the Kester deposit (Yana Plateau in Yakutia, Russia) are proved to be connected with a rare-metal complex of accessory minerals: montebrasite, columbite-(Mn), columbite-(Fe), tantalite-(Mn), Ta-bearing cassiterite, U-bearing microlite, W-bearing ixiolite, niobian ferberite, U–Hf-rich zircon, and rutile. Accessory wodginite was discovered at depths up 150 m association cassiterite. According content WO3 (1.23%–3.33%) values Mn/(Mn + Fet) Ta/(Ta Nb), Yakut is an intermediate mineral between hypothetical group—”wolframowodginite”. The discovery tungsten-bearing confirms widespread presence tungstic minerals Russian Far East. It also serves as indicator tin-tantalum-bearing pegmatites.
