Vladimir Kuleshov is a doctor of geology and chief researcher at the Laboratory of isotope geochemistry and geochronology at the Geological Institute of Russian Academy of Sciences. In 1974 he graduated from the Department of Historical and Regional Geology, Geological Faculty of Moscow State University, with a focus in Geological survey and prospecting of mineral deposits. He is a well-known expert in the field of stable isotope geochemistry, particularly endogenous and sedimentary mineral deposits, isotope geochemistry of evaporite formations and isotope chemostratigraphy of Upper Paleozoic deposits of Russia. The main objects of his current research are sedimentary manganese and phosphorite deposits all over the world. A large section of his research is working in the field of isotope geochemistry of carbonates from evaporite formations of oil and gas basins of the Pripyat Trough (Belarus), Siberia (Irkutsk amphitheater) and the Cis-Ural. He has taught at the Department of Lithology and Marine Geology at Moscow State University since 2002. Doctor Sc V. Kuleshov has authored more than 90 scientific articles in the Russian language including "The isotopic composition and origin of deep carbonates. Moscow, Science, 1986 and "Manganese rocks and ores: isotope geochemistry, origin, evolution of ore formation. Mocow, Scientific World, 2013.
