Stibnite closely coexists with cinnabar, and the content of stibnite increases slightly with the depth of Hg-Sb veins (Figs. 3 and 4b-c, h-i). The subtypes of ore bodies are represented by the No. 2, 3, 7 and 10 ore bodies in the southern ore block and the No. 16, 28, 55 and 45 ore bodies in the northern ore block, respectively (Fig. 2).

Antimony is rarely found in its pure state and most commonly occurs in nature as the sulphide mineral stibnite (Sb 2 S 3). It also occurs in more than 100 other minerals, usually as oxide, e.g., valentinite (Sb 2 O 3 ), and as antimonies of heavy metal sulphides such as tetrahedrite ((Cu,Fe,Zn,Ag) 12 Sb 4 S 13 ), livingstonite (HgSb 4 S 7 ) and ...

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 ...
