Composition of surface layer bottom sediments from the Chukchi Sea, supplement to: Astakhov, Anatoly S; Kolesov, Gennady M; Dudarev, Oleg V; Ivanov, M V; Kolesnik, A N (2010): Noble metals in the bottom sediments of the Chukchi Sea. Translated from Geokhimiya, 2010, 48(12), 1289-1301, Geochemistry International, 48(12), 1208-1219


Abundance of noble metals and bulk chemical composition have been studied in bottom sediments of the Chukchi Sea. Distribution of noble metals and their correlation with major and trace elements in the sediments have been analyzed using multicomponent statistics. It was established that average contents of noble metals in the bottom sediments of the Chukchi Sea significantly exceed those both in shelf terrigenous sediments and stratisphere. Osmium and iridium enrich mixed and pelitic sediments relative to shallow-water sediments and their influx is presumably determined by erosion of coastal and bottom unconsolidated deposits. High Ag, Ru, Au, and Pt contents were identified in clayey sediments enriched in biogenic elements in the some areas of the Southern Chukchi plain (Chukchi Sea) confined to intersection zones of submeridional and sublatitudinal structures of the graben-rift system, which formed in Mesozoic and activated in Late Cenozoic.
