Stibnite is an antimony trisulphide mineral with the chemical formula Sb2S3. It is a natural mineral source of the chemical element antimony (Sb), which is a lustrous grey metalloid, and it is mined primarily for this reason. Dioscorides, the Roman naturalist and the father of pharmacy, refers to stibnite as πλατυόφθαλμον ...

The formation of native antimony in stibnite may have been due to ore-forming fluids with low oxygen fugacity, in which the element Sb was reduced to form native antimony. Low oxygen fugacity is unlikely to be associated with pure magmatic fluids, so we infer meteoric fluids with low oxygen fugacity participated in Sb ore formation ( Li et al ...
