New type of gold mineralization of the Tyrnyauz ore cluster (Kabardino-Balkar Republic)

Resumo

Native Au on the northern flank of the Tyrnyauz ore cluster is related to the pyroxene–garnet association of skarns and is represented by separate idiomorphic ingrowths in rock-forming minerals of skarns and relatively isometric xenomorphic grains in the interstices. Gold mineralization can be attributed to the Au-skarn geological–industrial type with ores of a low-sulfide formation and Au–Bi–Te geochemical specialization.
