Archaeometry, EarlyView.ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and
