Abstract Iron sulfide (Fe-S) minerals such as mackinawite (FeS), greigite (Fe 3 S 4 ) and pyrite (FeS 2 are widespread on Earth, where their formation dissolution strongly linked to the biogeochemical cycles of iron, sulfur, carbon, oxygen, nutrients trace metals. Recent studies have shed light how microorganisms mediate formation, with breakthroughs biogenic pyrite. In this review, we highlight pathways Fe-S minerals, starting increasingly recognized roles Fe(III) intermediate sulfur species ( e.g. 0 polysulfides) during initial steps. The mechanisms by which affect mineral compiled discussed for low (25–35°C) high (≥ 80°C) temperatures, specific examples from experimental studies. morphology precipitation rates obtained experiments compared natural environments, similarities differences critically discussed. We then review current state art in context origin life environmental proxies biosignatures geological record using texture chemical isotopic compositions. end highlighting importance societal issues, sequestration organic acid drainages, metal recovery nitrate removal, potential use technological bio-materials future.
