Data on the abundance of petrogenic and trace elements (including rare earth elements) in the Quaternary deposits of Sevastopol Bay at the pre-technogenic stage of its development were obtained. Anomalies in the enrichment with Ag, Au, Hg, Pb and elevated levels of Cu, Zn, Cd, Sn, Sb in some layers were discovered. These features are apparently due to sulfide mineralization in the denudation area and the emergence of specific geochemical barriers (hydrodynamic and, possibly, saline ones) in the
