Abstract
Silicate melt inclusions were studied in the quartz phenocrysts from the Li-F granite porphyry of the Shumilov Massif, which are considered to be the sources of ore-bearing fluids of the Shumilov tungsten deposit. The estimated water content in the granite melt was 2.1–7.6 wt %, at a water pressure in the magmatic chamber of 3.1–5.2 kbar. It was concluded that the fluid-magmatic systems of the Shumilov and Spokoinoe tungsten deposits were formed at similar physicochemical conditions.
