Large-scale partial melting of deeply subducted continental crust: Evidence from alkali granite in the Sulu orogen

In this study, we conducted a comprehensive analysis including zircon U-Pb geochronology, the chemical composition of minerals and melt inclusions, as well as whole-rock elemental and Zn and O isotopic characteristics of the Tuofeng granites—a suite of alkali granites located in the ultra-high pressure (UHP) metamorphic belt of the southwest Sulu orogen.
