Orogenic goldAu (Sb)
- Type
- Orogenic gold-antimony in sulfide veinlets and quartz veins in schists
Second gold deposit of the Chinese South Tianshan, in schists interbedded with marble (Devonian-Carboniferous); over 34 lenticular orebodies controlled by EW to NE reverse faults. Stage I with arsenopyrite, pyrite, pyrrhotite and chalcopyrite (gold-arsenic), stage II with gudmundite, aurostibite and stibnite (gold-antimony). Ma et al. (2025): in situ δ34S of -2.9 to +0.8 ‰ and 206Pb/204Pb of 17.88 to 18.00: sulfur and metals from Upper Palaeozoic strata during regional metamorphism, with no known pluton. Coordinates from the article (42°23'02.4" N, 82°55'37" E, latitude minutes printed as "23′024″").
