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… CONTINUE READING
