Occurrence and transformation of schwertmannite (Sch) widely influence the speciation and distributions of iron and sulfur as well as pollutants in acid mine drainage (AMD)-impacted ecosystems. Despite extensive research on the biogeochemical fate of Sch in terrestrial systems, the mechanisms underl...
