The source of acidity in acid sulfate soils is the existence of appreciable pyrite and the lack of a comparable quantity of carbonate minerals to neutralize the acidity resulting from pyrite oxidation. Formation of pyrite in reducing marine and brackishwater sediments is a pervasive and well understood process (Berner, 1970; Pons, 1973).

Sep 17, 2019 Pyrite (FeS 2) is the most common sulfide mineral in coal and a major source of the sulfur in coal. Pyrite can form in peat while the peat is accumulating, or can form in peats from the introduction of sulfate (SO 4) into the peat if the peat was buried by marine waters (such pyrite is called syngenetic or authigenic pyrite).
