摘要
Fe, Cu and Zn isotopic compositions of 3 basaltic standard reference materials of BCR-2,BIR-1a and GBW 07105 were reported in this paper. The data were in good agreement with published data within uncertainties.The Fe,Cu and Zn isotopic data of basaltic reference materials provide a new standard for relevant research,and a method for evaluation of the quality of the whole process of sample preparation and isotope measurement.
