Quantitative analyses of different genetic coalpyrites and S/Fe ratios are also listed in Table 3(column 58). Obviously,oxidation order of coalpyrites is epigenetic coal pyrite > diagenetic coalpyrite > protogenetic coalpyrite. This order coincides with the variation rule of oxygen contents on the surface of coalpyrites.
