Abstract
This study evaluates for the first time Hf-isotope characteristics of zircon from dunite of the Kondyor massif, which is closely related to an economic platinum placer deposit. The significant range in εHf(t) values (from –8.4 ± 0.8 to 10.5 ± 1.3) in Mesozoic zircons indicates the interaction of a “juvenile” mantle source (εHf(t) = +15) with distinct magma sources, equivalent to a subcontinental lithospheric mantle and/or a continental crust. The peculiarities of the Hf-isotopic composition of Precambrian zircons (εHf(t) from –2.3 to +0.3) is consistent with their xenogenic origin and inheritance from basement rocks of the Siberian Craton.
