Zhanan
Eastern Kazakhstan, Zhanan gold-bearing tectonic zone (Semipalatinsk district), 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. Gold-sulfide ore and stibnite in foliated and brecciated zones of silicified subvolcanic basaltic and andesite-dacite porphyries and tuffaceous sandstones; lenses of 160 × (10-60) m and 1-12 m thick, 6.2-16.6 ppm Au, 0.05-4.02 % Sb; fine stibnite up to 50-60 % of some lenses near surface, superimposed on gold-sulfide ores.
