摘要：This study reports the archaeometallurgical analyses results on six slag remains obtained fromChaltasian, Iron Age II, in the Central Plateau of Iran, excavated by Islamic Azad University, Varamin-Pishva Branch. Metallurgical studies were carried out to identify oxides, Ca-rich silicates and metallicphases in the slag material, using wavelength dispersive X-Ray fluorescence (WDXRF), followedby an analysis of one sample under the polarizing microscope: plane polarized light (PPL) and crosspolarized light (XPL). Based on the analyses, it has been concluded that these six copper slag remainshave a considerable amount of silica, which had been added to the smelt to increase its fluidity.Analyses showed a clinopyroxene microstructure in a glassy matrix for five samples, and a baritesource, from a probable lead-zinc source in limestone, for the other sample. The absence of arsenic inthese copper slags could show a paradigm shift in copper production in this space-time grid. Accordingto the low amount of slag present on site, on the one hand, and the application of relatively advancedextraction technology on the other, this research introduces Chaltasian as an Iron Age II small copperproduction centre in the Central Plateau of Iran with a locally-developed copper extraction technology.
