Geology, mineralization, and fluid inclusion characteristics of the Meliksu reduced tungsten skarn deposit, Alai Tien Shan, Kyrgyzstan: Insights into conditions of formation and regional links to gold mineralization

The Meliksu W skarn deposit (∼10Kt WO3, with average grade of 6.6% WO3) in the Alai Segment of the Southern Tien Shan is related to an Early Permian granitoid pluton that comprises ilmenite-series to ilmenite-titanite-bearing, medium-K, metaluminous to peraluminous I-type granitoid (monzonite/diorite-tonalite-granodiorite to granite) rocks. There is a regional-scale continuum from these intrusions to transitional weakly reduced to weakly...
