Geochemical and Mineralogical Study of the Antimony (Sb)-mineralization at the north Pelion region, Magnesia, Greece.

Antimony (Sb) is consistently included in the European Union’s (EU) list of Critical Raw Materials (CRM) since its establishment in 2011, due to its economic importance and the EU’s supply reliance on imports from third countries (European Commission, 2023). Greece is one of the EU member states that host a significant number of antimony mineralization (both occurrences and deposits that were exploited in the past), located in central-eastern Macedonia, western Thrace, the eastern Aegean Sea, and the Pelion peninsula (Stergiou et al., 2022,2023; Kanellopoulos et al., 2024). Antimony mineralization at Pelion has never been the subject of systematic research, especially compared to other Greek antimony mineralization. The aim of this study is to determine the mineralogical and geochemical characteristics of the antimony mineralization at the Mantemia and Moni Panagias sites, North Pelion, in an attempt to determine the conditions of ore deposition.
