Abstract:
With the Re-Os isotopic technology, the Re-Os isotope composition of pyrites is identified, and the isochron age of(122±44)Ma is obtained. The initial ratio N(187Os)/N(188Os)of pyrite is 0.56±0.12, and the γOs value is between 197.46 and 394.16, with an average of 293.49. These data suggest a changing between the crust-derived and mantle-derived sources. Considering the ratio of w(Os)u versus w(Re)/w(Os), it is thought that the source of ore-forming materials may have the feature of crust-mantle derived mixture.
