N2 - A radiometric age of 83.4 ±3.2 Ma and initial 87Sr/86Sr of 0.75058 ±0.00068, indicative of sialic matter melting in the upper or middle crust, were established by the Rb-Sr method for the Verkhneurmi massif granite. From the early to the late emplacement phases, the granite is shown to become progressively enriched in Na + K, Li, Rb, Cs, Nb, Y, Yb, W, Sn, and F, and depleted in Ti, Fe, Mg, Ca, Ba, Sr, and Mo. Significant correlations were established between the alumina coefficient [Al2O3/(FeO + Fe2O3 + MgO)], total alkali content (Na2O + K2O), and fractionation degree of the granite [lg (Rb/Ba)]. The most differentiated rock of the massif is the Li-F-leucogranite, which is the likely source of the fluids responsible for metasomatic reworking of rhyolite and granite to produce the Sn-bearing quartz-topaz-siderophyllite greisen of the Pravourmi deposit.
