Genesis of the Maikhura tungsten-tin skarn deposit, Tajik Tien Shan: Insights from petrology, mineralogy, and fluid inclusion study

The Maikhura W-Sn skarn deposit is situated in the Gissar Segment of the Southern Tien Shan. It associates with a Late Carboniferous-Early Permian composite granitoid pluton, which includes earlier ilmenite-series, transitional metaluminous to peraluminous, I-type granodiorite, and later magnetite-series, biotite to biotite-tourmaline granite/leucogranite.
