Alkalinity Production Coupled to Pyrite Formation …
Whether sulfate, organic carbon or reactive iron limits pyrite formation is highly site specific (Morse et al., 2007), hence modeling these processes is a challenge. This study aims to evaluate TAlk production coupled to pyrite formation in blue carbon ecosystems and to examine whether pyrite stocks represent a significant blue carbon sink.

Iron pyrite, roasting
The third major source of sulfur production is metal sulfide minerals, such as the mineral iron(II) disulfide (also known as iron pyrite). Roasting iron pyrite in the absence of air causes the sulfur to disproportionate (react with itself) to form iron(ll) sulfide and el ental sulfur. Total 1991 world production of sulfur in all forms was 55.6 ...
