  • Sulfur in coals: A review of geochemistry and origins

    For mediumsulfur (1 to < 3% S) and highsulfur (≥ 3% S) coals, there are two major sources of sulfur: 1) parent plant material, and 2) sulfate in seawater that flooded peat swamps Abundances of sulfur in coal are largely controlled by the degree of seawater influence during peat accumulation and by postdepositional changes (diagenesis) In highsulfur coals, seawater sulfate diffuses into
