Dr. Igor I. Kolodeznikov is one of the leading scientists in Russia in the field of magmatic geology, who made a significant contribution to the development of problems of volcanism and rifting in the Northeast of the Asian continent. He has conducted field geological studies of Mesozoic and Paleozoic volcanism and rifting in almost all regions of Northeast Yakutia: in the South Verkhoyansk region, in the mouth of the Lena River, in the Okhotsk and Kolyma-Omolon regions.

In his works I.I. Kolodeznikov showed that the Middle Paleozoic era was a turning point in the geological history of the Northeast Asian continent, which largely determined the further history and minerageny of the region, since the development of the Middle Paleozoic rift system led to the split of the eastern part of the ancient continent of Eurasia and the formation of the Late Paleozoic-Early Mesozoic passive continental margin.

Author of 130 scientific and scientific-methodical works, including 11 monographs.

Awards and Honors: Honored Geologist of the Republic of Sakha (Yakutia) (2006), Honorary Worker of Higher Professional Education of the Russian Federation (2007), Honorary Citizen of Ust-Aldan ulus (2011). In 2014, the President of the Russian Federation V.V. Putin expressed gratitude to I.I. Kolodeznikov for the achievements in labor, many years of conscientious work and active social activity. Honorary Citizen of the Republic of Sakha (Yakutia) (2018).
