From the history of scientific researches of Ukhta geological prospecting expedition

The main areas of research of geologists of Ukhta geological prospecting expedition was metallogeny, stratigraphy, bauxites and placers formation. The result of metallogenic research (under the guidance of V.G.Cherny) was the metallogenic map of Timan and predictive maps of deposits of metals. The working scheme of the Precambrian of Timan was compiled, approved by the International Stratigraphic Committee of the USSR on the Precambrian. As for bauxites, the weathering crust was studied, the Devonian bauxites were discovered, their genesis and mineral composition of certain types of bauxites was refined, the methods of searching were developed and a prognostic map compiled (the works were executed by A.M.Plyakin, B.A.Yatskevich, V.A.Lebedev, et al.). The works on alluvial deposits (executive V.A.Dudar) have led to the discovery of polymineral placer Ichetyu and placer gold deposits in the Timan. All the thematic work was carried out in scientific collaboration with academic science and other research institutions of the country.
