Provenance discrimination of sixty four obsidian artifacts found in the Korean Peninsular has been carried out using major elements, minor elements and magnetic properties. Most of obsidians in this study were classified into the subalkaline series based on the contents of $Al_2O_3,\;CaO,\;and\;Na_2O+K_2O$ in samples. Provenance & obsidians were classified into three major groups using major elements and minor elements analyse. This result suggests that there are no correlations among the three groups whose provenances are different. Although the magnetic properties of obsidians do not yield clear groupings according to the archaeological site, the bivariate plot for the magnetic susceptibility and the saturation isothermal remanent magnetization shows a rough correlation with the results of major and minor elements analyses.
