The investigations of iron technology of different cultures developed within the territory of Eastern Europe are of great importance. The progress of iron production from using meteoric iron to bloomery iron-making process, the chronology of the development of iron technology, and influence of paleoenvironment on spreading of this technology, all that allows us to answer the question of the appearance of the technology of iron in Eastern Europe. Expansive archaeological data from main archaeological sites of Eastern Europe (Boldyrevo I, Saharna Mare, Butor, Kelermes, Tarasova Balka) and detailed
complex archeometric investigations must be united. The complex of methods: metallography, m-CT, thin section analysis, geochemical and mineralogical analysis using SEM-EDX, WD-XRF and рXRF, isotopic (Pb-Pb, He) methods were applied for study of iron artifacts. The first results have shown the
differences in sources of raw materials and technology of early iron production
