Abstract
The article deals with genesis of chamosite zone in Elov supergene nickel deposit after the example of clinochlore-brindleyite-chamosite nickel ore. According to obtained data, isotope ratio 34 S/ 32 S in millerite from these ore type varies from –35,5 to –45,6±0,6 ‰. This value corresponds to sedimentary rocks und testifies surface exogenous genesis of chamosite nickel ores.
