About concentrations of gold in the pyrites of gold deposits of Central Asian Folded Belt
The paper presents the results of the analyses of gold in pyrites of a number of gold deposits of the Central Asian Folded Belt (Western Kalba in Eastern Kazakhstan, Rudnyi Altai, Kuznetskii Alatau, Eastern Sayan, Mountain Altai, Tuva, Mongolia). It is shown that gold was found in all samples of pyrite from 0.04 to 70.0 ppt. The highest gold concentrations were observed in arsenic pyrite of Bakyrchik. The distribution of gold in pyrites is uneven. The pyrites of productive mineral associations are enriched with metal the most, the early poorly gold association and pyrites of ore zone metasomatites - the least.
