We have analysed chemical of nepouites. NiO content in then ranges from 13,00 to 35,18 %, MgO from 18,29 to 44,61 %, i.e. the composition of nepouite corresponds to the composition of Mg-nepouite. General row of chemical element mobility in lizardite – nepouite ores of the Elov supergene nickel deposit is the following: (Mo, Sb, Se, W)20-35 > (Sn, As, Ni)10-20 > (Pb, Be, U)3-7 > (Ti, Ga, Mn)1-3 > (Th, Rb, Si)~1 > (Al, V, Co, Tm, Zn, Mg)0,6-0,9 > (Yb, Ca, Cu)0,4-0,5 > (Sc, Cr, Zr, Sr, Ba, Y, Ta, TR)0,1-0,4 > (Cs, Nb; Ag, Te, Bi, Au)< 0,01-0,1.
The article deals with the distribution of groups of trace elements in four selected types of metasomatic rocks and ores in the Elov deposit: chamosite metasomatic rocks and ores, which are three mineral species: a – chamosite, в – clinochlore –brendleyit-chamosite, с – clinochlore-talc-chamosite, goethite metasomatic rocks and ores, nepouite-chrysotile-lizardite metasomatic rocks and ores, and lizardite-chrysotile serpentinites. Also calculated the coefficients of accumulation of trace elements and formulated conclusions about elements are accumulation or elements are weathered of the above types of metasomatic rocks and ores of the Elov deposit.
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.
