“…The foundation and development of ancient coastal cities are typically associated with the accumulation of pollutant metals in nearby soils and sediments, due to water run‐off particle dispersion from metallurgic activities, as has been shown for several harbor basins from Antiquity (Delile et al, ; Elmaleh et al, ; Le Roux, Morhange, & Veron, ; Le Roux, Veron, & Morhange, ; Marriner, Morhange, Kaniewski, & Carayon, ; Stanley, Carlson, Van Beek, Jorstad, & Landau, ; Véron, Morhange, Poirier, Angeletti, & Bertoncello, ). Consequently, harbor sediment geochemistry may provide a good proxy for distinguishing natural from artificial coastal sedimentary successions.…”
