Organic matter in ground- and surface waters in the area of the Annenskii geothermal field, Russian Far East

详细

The paper presents author’s data on the composition of water-soluble organic matter in thermal, cold groundwaters, and surface waters in the Annenskii geothermal field. The waters contain 75 organic compounds of 13 homologous series, with 72 of these compounds identified in the thermal waters. The compounds are mostly of biogenic origin. Organic matter in the thermal waters differs from that in the cold groundwaters in containing nitrogen-bearing compounds, isoalkanes and alkenes. The compositional specifics of the saturated hydrocarbons suggests their partly abiogenic origin.
