Deep abiotic weathering of pyrite | Science

2020-10-23 · Pyrite, also called fool''s gold, is an iron sulfide mineral that is very commonly found in rock but is almost nonexistent in sediments today. Pyrite oxidizes quickly and is a major source of sulfur to the ocean, but it is also a proxy for the oxygen content historically in Earth''s atmosphere. Gu et al. conducted a set of detailed observations of the pyrite oxidation process in a shale unit.
