Epithermal depositsAu-Sb
- Type
- Gold-antimony (berthierite-stibnite assemblage superimposed on gold-quartz)
Gold-antimony occurrence in the axial part of the Adycha-Taryn fault: Late Cretaceous quartz-stibnite-berthierite assemblage emplaced during sinistral strike-slip and superimposed on older gold-quartz mineralisation (reaction chalcostibite, ullmannite, Sb-rich pyrite, aurostibite and "spongy gold"). Gamyanin et al. (2018): milky quartz from +16.1 to +19.2 ‰ (fluid +4.9 to +8.2 ‰ at 200 °C), ankerite from -12.1 to -9.5 ‰ in δ13C, stibnite from -5.3 to +0.2 ‰: significant magmatic input, carbon lighter than in gold-quartz. Two-stage formation, antimony massively reworking the early gold-quartz matrix (Fridovsky et al., 2014). Occurrence values: milky quartz +16.1 and +16.3 ‰; ankerite -9.5 ‰ in δ13C and +15.0 ‰ in δ18O; δ34S: arsenopyrite +1.6, stibnite -2.6; -3.5; -4.1 ‰. Coordinates not published (schematic map only).
