Extremely light potassium isotope compositions of the continental eclogites and high-pressure metamorphic veins reveal the fluid-rock interactions in subduction zones

Table S1-S3 report the mineral assemblages, K isotopic compositions and reconstructed K budgets of the investigated eclogites, amphibolites, and veins. Table S4 shows the metamorphic dehydration modelling results of K isotope system during subduction. Table S5 shows mass balance calculations results between the K loss fraction and their isotopic compositions during fluid escape.
