Protracted Recharge Triggers an Early Eocene Supereruption in Southern Tibet

The dataset includes Text S1-S2, Figures S1-S4, and Tables S1-S5. • Text S1 to S2 contains detailed methods and latent heat effect discussion; • Figures S1 to S4 provide initial conditions of modelling, Cathodoluminescence (CL) and Micro X-ray fluorescence (μXRF) images of selected quartz grains, and heat conduction modelling results with considering latent heat; • Table S1 lists the whole-rock compositions of collected samples; • Tables S2 to S3 list the meaning and units of the parameters in diffusion and heat conduction modelling; • Tables S4 to S5 summarize raw data of Electron Probe Microanalysis (EPMA) and diffusion results.
