Across-arc variations of potassium isotope compositions in a fluid-dominated subduction zone and implications for global potassium recycling-Data

Data file for "Across-arc variations of potassium isotope compositions in a fluid-dominated subduction zone and implications for global potassium recycling". Included are data for supplementary Tables S1-S2. Table S1 reports the K isotopic compositions of the Kamchatka arc lavas. Table S2 shows the compiled Major, trace elements, stable and radiogenic isotopic compositions of Kamchatka arc lavas.
