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 ...
