Multistage W-mineralization and magmatic-hydrothermal fluid evolution: Microtextural and geochemical footprints in scheelite from the Weondong W-skarn deposit, South Korea

Weondong deposit is one of the W-skarn deposits in South Korea, and main ore mineral is scheelite (CaWO4). Scheelite occurs in both a massive skarn zone (MSZ; Type I) and a quartz porphyry fracture zone (QPFZ; Type II), forming solid solution with powellite (CaMoO4). We examined the relationship between the evolution of ore-forming fluids and formation of multistage scheelites based on microtextural and geochemical features. Type I scheelites...
