Laboratory of Geochemistry

Founded in 1988.
Founders - Professor Esper Ostroumov and Honored Worker of Science, Professor Igor Volkov. Igor Volkov was the first head of the laboratory.
Since 2002, the laboratory was headed by Alexander Dubinin.

Rimskaya-Korsakova, researcher Oksana Chicherina, researcher Eugenia Berezhnaya, researcher Tatyana Demidova, senior engineer Olga Netuzhilkina, assistant Lyubov Semilova, assistant Yuriy Karzhavin, assistant Timur Safin

Well-known scientists had previously worked in the lab: Professor Lev Gurvich, D.Sc. Vyacheslav Sval’nov, D.Sc. Maria Nesterova, D.Sc. Maria Barkovskaya

The main directions of the research:

• Development of methods for the determination of trace elements in the water and sediments
• Investigation of the sulfur forms in the sulfidic water
• The isotope composition of sulfur, carbon, oxygen and hydrogen in water basins with anaerobic conditions
• Mathematical modeling of biohydrochemical processes
• Geochemistry of sedimentation and ore-forming processes in the oceans and seas
• Indicator role of trace elements in the ore-forming processes in the ocean
• Genesis of ferromanganese nodules and crusts in the oceans and seas
