The Russian Academy of Sciences has announced the winners of the 2024 competition for medals with prizes for the best scientific works of young scientists and students. One of the laureates was a postgraduate student Faculty of Geology and Geophysics (FGG) of NSU Alexey Tarasov. He received the award in geology, geophysics, geochemistry and mining sciences for his research on melt inclusions in minerals of mantle peridotite xenoliths.
We talked to Alexey about his scientific path, research topic, participation in the competition and plans for the future.
— How did you end up at NSU?
— I entered NSU in 2018 after finishing school in Barnaul, based on the results of the Unified State Exam. I studied for a bachelor's degree at the Faculty of Geography and Geography, then entered the master's program. Now I continue my studies in graduate school.
— Why did you choose the Faculty of Geology and Geophysics?
— I have been interested in minerals since childhood, I had a small collection at home. I attended the "Young Geologist" club — there was one in Barnaul. Gradually, my hobby turned into a professional interest. I knew that Novosibirsk had a strong school in geochemistry, and this played a decisive role. There was no doubt where to go.
— Tell us about your scientific work for which you received the Russian Academy of Sciences medal.
— The overall goal of all our work is to understand how diamond deposits are formed. Diamond is a form of carbon that is stable only under very high pressure, so it forms deep in the mantle, at depths of 150–160 kilometers and more. Most diamonds formed more than 2.5 billion years ago and are still in the mantle because it is too deep to mine them.
But there are kimberlite magmas. They form in the mantle and, unlike most other magmas, rise to the surface very quickly. In doing so, they take with them fragments of mantle rocks – so-called xenoliths, and minerals – xenocrysts. Sometimes – with diamonds.
When magma reaches the surface, it forms kimberlite pipes, which are the main source of diamonds in nature. But what is kimberlite magma? What it consists of, where it comes from, and under what conditions it originates – is still not exactly known. This is a key scientific question, and I am working on solving it.
– How do you research this?
— I study melt inclusions in xenolith minerals. These are tiny drops of magma that were “sealed” in crystals during their growth and preserved in their original form. These inclusions provide a unique opportunity to reconstruct the composition of kimberlite melts at the moment of their origin — before all the changes and contaminations that occur during their ascent to the surface.
The composition of these inclusions can tell us about the temperature and pressure of formation, and the type of rock from which they formed. This helps us get closer to understanding where and how new kimberlite pipes can form, and therefore potentially predict where diamonds can be found.
— What, in your opinion, helped you receive the RAS medal?
— It’s hard to say how exactly the selection took place. But I think several factors played a role. I tried to show that my work was not just fundamental, but also had potential applied significance. In addition, at the time of application, I had six published articles in which I was the author or co-author.
But, to be honest, the main thing is not "what", but "who". My scientific supervisor Alexander Viktorovich Golovin. He insisted that I participate in conferences, helped with writing articles, tolerated my mistakes, demanded high quality. It was he who convinced me to apply for the RAS competition. In addition to him, other colleagues at the institute and teachers at the faculty supported me. Without them, nothing would have happened.
— How did the competition itself go?
— It was quite simple: you had to prepare an application, attach a research paper (in my case, it was a master's thesis), provide a list of publications, and sign documents. There were no in-person stages — everything was done in writing.
— What are your plans next?
— I am continuing my postgraduate studies and working at the Institute of Geology and Mineralogy of the Siberian Branch of the Russian Academy of Sciences. I plan to defend my PhD thesis in 2027. I am currently finishing my first article, where I am the first author, and I want to publish it in a foreign journal of the 1st–2nd quartile. I already sent it six months ago, but was rejected. The reviewers pointed out the weak discussion and insufficient English.
Now I am rewriting the text, looking for a translator and funding for professional translation. In parallel, I am working on the following articles. My supervisor has set a task – five articles by the end of my postgraduate studies. To be honest, I am not sure that I will cope, but I will make every effort.
The Russian Academy of Sciences holds an annual competition for medals and prizes for young scientists and students. In 2024, 21 young scientists and 21 students received awards. Each laureate receives a medal, a diploma, a badge, and a cash prize of 100,000 rubles for young scientists and 50,000 rubles for students.
The competition covers key areas of natural, technical and human sciences and is held with the aim of encouraging young scientists, supporting professional growth and enhancing the prestige of research activities.
We congratulate Alexey Tarasov on his well-deserved award and wish him success in his future scientific research!
