Abstract

Isotope ratio 87Sr/86Sr was determined for the first time for the Ufalei and Sakhara supergene nickel deposits. The average obtained 87Sr/86Sr ratio in the Sakhara deposit (0,70838) is higher then in the Ufalei deposit (0,70697). In both deposits 87Sr/86Sr ratio increases from low-altered serpentinite rocks of the lower part of the deposits (0,70583 and 0,70687) to exogenous iron-oxide rocks of the upper part of the deposits (0,70917 and 0,71004).
