Table 1 for this article includes K isotopic ratios (‰) of anorthoclase megacrysts and host lavas in Damaping basalts. Supplementary information for this article includes: 1. Plots of SiO2 vs. K2O and the Rayleigh fractionation modelling for K isotopes in the Hannuoba basalts (Figure S1); 2. Hand specimen photos of anorthoclase megacrysts (Figure S2); 3. Profile and elemental analyses of anorthoclase megacrysts (Tables S1–S3); 4. Correlation diagrams of elements in anorthoclase megacrysts (Figure S3).
