Dissolved chemical elements in river waters of the Wrangel Island, supplement to: Lavrushin, VYu; Gruzdev, A R (2012): The salt composition of rivers in Wrangel Island. Translated from Litologiya i Poleznye Iskopaemye, 2012, 1, 3-20, Lithology and Mineral Resources, 47(1), 1-17


Pioneer information about chemical composition of river waters in the Wrangel Island has been obtained. It is shown that water composition reflects the lithogeochemical specifics of primary rocks and ore mineralization. In contrast to many areas of the Russian Far North river waters of the island are characterized by elevated background value of total mineralization (i.e., total dissolved solids, TDS) (0.3-2 g/l) and specific chemical type (SO4-Ca-Mg). This is related to abundance of Late Carboniferous gypsiferous and dolomitic sequences in the mountainous area of the island. It has also been established that salt composition of some streams is appreciably governed by supergene alterations of sulfide mineralization associated with quartz-carbonate vein systems. They make up natural centers of surface water contamination. Waters in such streams are characterized by low pH values (2.4-5.5), high TDS (up to 6-23 g/l) and SO4-Mg composition. These waters are also marked by anomalously high concentrations of heavy and non-ferrous metals, as well as REE, U, and Th.
