Anatoly Alexandrovich Makhnach (b. 13.07.1951, Moscow), a geologist. Academician of the National Academy of Sciences of Belarus (2003; corresponding member since 1994), Doctor of Geologo-Mineralogical Sciences (1990), Professor (2001).
Developed lithohydrogeochemical direction in the theory of lithogenesis, developed a hydrogeological concept of sedimentary catagenesis, gave a comprehensive description of transformations of polyfacial deposits in a hydrogeochemical environment associated with evaporites, deepened understanding of the behavior of stable isotopes of carbon, oxygen and sulfur in the process of halogenesis. Studying the geological structure of the territory of Belarus: described catagenetic changes of intersalt and subsalt deposits of the Devonian, carbonate and flint nodules of the Devonian and Cretaceous strata, laid the foundation for studying the geochemistry of stable isotopes in the region, participated in solving problems related to the development of iodine-bromine brines, prospecting and exploration of oil, rare and scattered elements.
Author of about 200 scientific papers, 14 monographs.
The Leninist Komsomol Prize of Belarus in 1980 for the series of works "Lithogenesis and hydrogeochemistry of the Devonian sediments of the Pripyatsky oil-bearing basin (in connection with the search for oil fields and the assessment of the prospects for the national economic use of iodine-bromine brines)". Prize of the National Academy of Sciences of Belarus in 1993 for the monograph "Catagenesis and groundwater".
