Electron probe microanalysis compositional maps (wt.%) and Raman data for the manuscript by Herviou et al. (2026, Scientific Reports): "COH fluids and melts drive mantle refertilization and organic synthesis in nascent subduction zones"

Dataset associated with Herviou et al. (2026), Scientific Reports: “COH Fluids and Melts Drive Mantle Refertilization and Organic Synthesis in Nascent Subduction Zones”. The dataset includes the raw analytical data used in this study: Raw compositional maps acquired by electron probe microanalysis of a polymineralic inclusion and its host garnet from sample SE123L. Raw 3D Raman mapping data of a multiphase inclusion and its host garnet from sample SE1367.
