Researchers and archeologists have always been interested in the elemental analysis of obsidian artifacts. Measurement of the elemental composition of obsidians provides a lot of information about trade and exchange between different regions and cultures in early societies. This paper reports and discusses elemental composition results obtained from analysis of 17 obsidian artifacts excavated in two seasons in 2018 and 2019 from the Tole Khari prehistoric site in the Pasargad complex in the Fars Province of Iran. Elemental analysis of these obsidians performed by micro-PIXE technique in Van de Graaff Laboratory in the Nuclear Science & Technology Research Institute (NSTRI) in Tehran, Iran. In this research, to study the provenance of obsidians obtained from Tal Khari, we combined and compared our results with elemental composition results reported from known sources of obsidian in Anatolia and Armenia. The results show that the obsidians from Tole Khari Tolclassified into two different groups based on elemental composition, in particular according to the concentration of Fe2O3, MnO, TiO2, and Al2O3. By comparing the obsidians of Tole Khari with obsidians from various sites in Anatolia and Armenia, it was found that the first group of obsidians from Tole Khari overlaps with obsidians from Bingol A in Anatolia, and the second group of these obsidians fits into obsidians from Nenezi Dag, Pasinler and Meydan Dag in central and eastern Anatolia. Therefore, it is probable and possible that the obsidians excavated in Tole Khari have supplied from known obsidian sources in Anatolia using a very long range of trade and exchange network, which was about 1000 to 1900 km.
