Iron isotopic fractionation by magmatic-hydrothermal fluid-melt interaction in the Himalayan leucogranites [PDF]

Fundamental Research
Iron (Fe) isotopes have been used to trace magmatic evolution (e.g., mineral fractional crystallization, partial melting degree, and fluid exsolution), but the behavior of Fe isotopes in magmatic-hydrothermal processes remains poorly constrained. Here we

Lithium mica clasts document magmatic evolution prior to eruption in the macusani volcanic field in peru [PDF]

Scientific Reports
Typically found in rare-metal granites and pegmatites, lithium micas are increasingly considered a resource for lithium as global demand surges. In a recently discovered major lithium resource within the Macusani Volcanic Field in Peru, lithium mica ...

Structural changes in silicate melt: A record from high-field strength elements in the Himalayan Cenozoic leucogranites

Frontiers in Earth Science, 2023
Most Himalayan Cenozoic leucogranites are peraluminous magmas that have experienced various degrees of fractional crystallization. These leucogranites are characterized by relatively high degrees of heterogeneity in their elemental compositions.
