Sulfur in coals: A review of geochemistry and origins

For low-sulfur coal (< 1% S), sulfur is derived primarily from parent plant material. For medium-sulfur (1 to < 3% S) and high-sulfur (≥ 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
