Data associated to GCA submission-Shuai Kang et al.

This dataset contains all numerical data used in the preparation of the manuscript entitled [Potassium isotopic variabilities in coals induced by magmatic and submarine exhalative hydrothermal activities], submitted to Geochimica et Cosmochimica Acta. It includes measurements of major element oxides, ash yield, quantitative mineralogy, potassium isotopic compositions, and elemental ratios for the studied coal samples. The dataset contains all values required to reproduce the tables and figures presented in the manuscript.
