Lithic arrowheads: Siliceous raw material sources and technology in Southern Portugal

This analysis focused on one hundred and fifteen lithic arrowheads recovered from the Zambujeiro Mitra 2 dolmens, funerary monuments in Évora, Portugal. These were analyzed by noninvasive minimally invasive analytical techniques, including handheld X-ray fluorescence (hXRF), variable pressure scanning electron microscope coupled with energy dispersive spectrometry (VP-SEM-EDS), laser ablation inductively plasma mass (LA-ICP-MS) to establish sources of raw materials used manufacture these compare cluster different artefacts. The found be suggesting that long-distance trade routes extending south, east possibly west place Southern Iberia during Neolithic Chalcolithic periods. Whether this difference is related availability throughout time, procurement strategies, or simply choice, remains unknown. associated Dolmen also seem have a greater range than those connected Dolmen.
