Dal'ny I (Bakyrchik field)
Eastern Kazakhstan, Bakyrchik district (Parallel'naya zone), Kazakhstan
Orogenic goldAu (Sb)
- Type
- Disseminated gold-sulfide in black shales, with late antimony
West Kalba gold belt (Ob-Zaisan Hercynides), in Carboniferous carbonaceous terrigenous-carbonate rocks; invisible gold in disseminated pyrite and arsenopyrite, close to the Carlin type according to the authors, late antimony (stibnite in quartz-stibnite veins and breccias) emplaced during extension. Quartz-stibnite veins up to 2 m thick, separate from the main gold-sulfide ores, with marcasite, cinnabar, native Ag, Sb and Au; Au and Sb secondary haloes do not coincide. Coordinates not published.
