Complex biogeochemical characteristics of the Tumnin springs thermal water

The results of complex biogeochemical exploration of the Tumnin geothermal deposit thermal water are given in the paper. The thermal water is slightly mineralized, alkaline, hydrocarbonate-sodium. The microelement composition is characterized by a prevalent content of arsenic, iron, manganese, molybdenum, silver, and chromium. Terpenes, alkanes, isoalkanes, etc. predominate among organic compounds. The distribution of hydrocarbons molecular mass indicates a biogenic, mainly bacterial, genesis of organic matter.
