The coincidence degree between the geochemical behavior of elements and the periodic variation of elements based on geochemical data of C2 coal seam in the Fengfeng mining area of the Handan Coalfield in Hebei, China

In this data-set, based on the geochemical data of C2 coal seam in the Fengfeng mining area of the Handan Coalfield in Hebei (China), where provided ideal coal samples changing continuously from low-rank metamorphic coal to high-rank metamorphic coal, the coincidence degree (or similarity degree) between the geochemical behavior of 57 elements and the periodic variation of elements during the thermal metamorphism process is calculated.
