Whole-rock and mineral geochemical, and zircon U–Pb geochronological data for high-grade metamorphic rocks and granitoids from the eastern Gangdese arc
Abstract:
We conducted a detailed petrological, geochemical, and geochronological study of migmatites from the eastern Gangdese magmatic arc, focusing on metamorphic rocks and associated granitoids (leucosomes). The datasets include mineral compositions (EPMA), whole-rock major and trace elements (XRF), zircon U–Pb ages and trace elements (LA–ICP–MS), zircon Lu–Hf isotopes (MC–ICP–MS), and whole-rock Sr–Nd isotopes (MC–ICP–MS). Our study aims to reveal the rock types of the arc crust in different periods, and to constrain the timing and P–T conditions of metamorphism and anatexis.
