Analytical methods for whole-rock geochemistry, monazite U–(Th)–Pb geochronology, Sm–Nd isotopes, and mineral chemistry of leucogranites from the Nyalam segment of the South Tibetan Detachment System, central Himalaya

This method describes the analytical procedures for whole-rock geochemistry, monazite U–(Th)–Pb geochronology, Sm–Nd isotopic analysis, and mineral chemistry of leucogranites from the Nyalam segment of the South Tibetan Detachment System, central Himalaya. Whole-rock compositions were determined by XRF and ICP–MS, and fluorine concentrations by a fluoride ion-selective electrode method. Monazite U–(Th)–Pb ages were obtained by LA-ICP-MS, and Sm–Nd isotopic compositions by LA-MC-ICP-MS. Mineral compositions were analyzed using electron probe microanalysis (EPMA). The workflow ensures reproducible and comparable analytical results.
