My research focuses on the genesis of base metal and critical metal mineralization in magmatic–carbothermal environments. I investigate the petrological and geochemical processes controlling metal enrichment through integrated fluid–melt inclusion studies, mineral chemistry, and thermodynamic approaches. My work particularly examines the role of lithospheric mantle redox evolution, metasomatism, and melt–fluid interactions in governing metallogeny and magma evolution. By linking deep lithospheric processes to ore formation, my research aims to advance understanding of critical mineral systems and their exploration potential in plume-related magmatic settings. I am also interested in applying experimental petrology to constrain the physicochemical conditions of ore-forming processes.
