Geology from hand to hand (to the 85th anniversary of the Professor Aleksey Ivanovich Trubachev)

This article is devoted to the Professor Aleksey Ivanovich Trubachev who is one of the most famous graduates of the Irkutsk Polytechnic Institute (now Irkutsk National Research Technical University), and his role in the formation  of a young geologist. Summarized published materials of the author of the article and his memoirs were transformed into  an essay on the life and creative activity of Aleksey Ivanovich Trubachev. Immediately after the graduation, he was sent to Trans-Baikal Integrated Research University (Chita) and joined a group of researchers investigating the unique Udokan deposit of copper sandstones and shales, which was headed by a well-known scientist, Deputy Director of the Institute Leonid Frantsevich Narkelyun. The largest works of A.I. Trubachev deal with the study of the material composition of the Udokan deposit ore bodies, the results of which are reflected in his candidate's dissertation defended at the Irkutsk Polytechnic University and in his doctoral dissertation defended in Novosibirsk. In all his works A.I. Trubachev proved the primary sedimentary genesis of the stratiform ores of the Udokan deposit, which was confirmed by the results of detailed exploration. In 1974, he started his teaching career. Today Aleksey Ivanovich is a professor at the Department of Minerals and Secondary Raw Materials Processing at the Trans-Baikal State University. For the period of his professional career, he has published 376 works, including 18 monographs, 19 teaching aids and textbooks on mineralogy, petrography and industrial mineralogy. A.I. Trubachev is actively involved in the creation of the unique mineralogical museum at the TransBaikal State University. The article pays special attention to the role of A.I. Trubachev in the formation of a young geologist during field works at the Udokan deposit. Field production practice is a major in the formation of a young geologist. In this case the most important things are the trust of the field mentor and early independent routing. Geologists and scientists like Professor A.I. Trubachev with extensive field and pedagogical experience certainly belong to the golden fund of the scientific and pedagogical personnel of Siberia.
