“…19,22,34,35 More recently, the Fe isotopic composition of pyrite is suggested to shed light on the formation of various types of sulde ore deposits, including magmatic-hydrothermal Sn-W deposits, 36 hydrothermal Au deposits, [37][38][39] porphyry Cu (-Mo) deposits, [40][41][42][43] skarn Cu-Fe deposits, 44 epigenetic sediment-hosted Cu-Co deposits, 45 sediment-hosted stratiform sulde deposits, 46 and sulde deposits on the modern seaoor. [47][48][49] The chemical zoning of pyrite can record a wealth of information during magma evolution and metamorphic reaction (e.g., ref. 33, 50 and 51).…”
