Pekov, Igor Viktorovich

Born March 16, 1967 in Moscow .

In 1989 he graduated from the Geological Department of Moscow State University with a degree in geology and geochemistry, specializing in mineralogy.

Since 1989 he has been working at the Department of Mineralogy of the Geological Faculty of Moscow State University. Since 2015, he has been the chief researcher.

In 1997 he defended his thesis on the subject “Mineralogy of rare-earth elements in high-alkaline pegmatites and hydrothermalites (on the example of the Khibinsky, Lovozersky and Ilimausaksky massifs)”.

Since 2000, at the same time, he has been working at the Laboratory of Geochemistry of Alkaline Rocks, GEOCHI RAS .

In 2005 he defended his doctoral dissertation on the topic "Genetic mineralogy and crystal chemistry of rare elements in highly alkaline post-magmatic systems."

In 2012, he was awarded the academic title of professor in the specialty "Mineralogy, Crystallography." Professor of RAS ^[1] .

On October 28, 2016 he was elected a corresponding member of the Russian Academy of Sciences in the Department of Earth Sciences, section of geology, geophysics, geochemistry and mining sciences ^[2] .

Since 2017, he has been working as a leading researcher at the Mineralogical Museum named after A.E. Fersman RAS (part-time) ^[3]

Scientific activity

He is a specialist in the fields of mineralogy and geochemistry of alkaline post-magmatic systems, granite pegmatites, an exhalation post-volcanic formation and hypergenesis zone of chalcogenide deposits, as well as mineralogy, geochemistry and crystallochemistry of rare elements, crystallochemistry and properties of zeolite-like minerals and synthetic compounds, mineralogy, material science. The main works are related to the study of complexes of alkaline rocks and granite pegmatites of the Kola Peninsula, the Middle and Southern Urals, Greenland, Canada, Germany, the fumarole fields of active volcanoes of Kamchatka, the oxidation zone of ore deposits in Altai, the Caucasus, the Urals, Greece, Chile, as well as experimental research new zeolite-like materials based on silicates with heteropolyhedral frame and layered structures.

In 2016, he openly and thoroughly studied 202 new minerals, of which 122 are the leading author (both of these indicators are the highest in the entire history of world mineralogy) ^[4] .

Among these minerals are representatives of 38 new structural types, and some mineral species are unique and make us reconsider a number of previously existing geochemical and crystallochemical representations. These include:

• pautovit - cesium sulfide
• niveolanite - beryllium carbonate zeolite structure
• ekspleksit , kaskasit and manganokaskasit - a new family of layered hydroxide sulfides of niobium and molybdenum
• catharsite , arsenatrotitanite - titanium arsenates
• magnesiotantalite - magnesium tantalate
• genlesite - tin sulfate
• chrysotallite - thallium chloride
• garlic - orthosilicate with two hydroxyl peaks at each Si tetrahedron
• shiroshinit - mica with sodium in the octahedral layer.

Based on mineralogical data, I.V. Pekov developed new aspects of concentrated state geochemistry and genetic crystal chemistry for a number of rare elements (Rb, Cs, I, Be, Nb, Zr, REE), As, Cu, Zn, as well as for common elements, which are in atypical forms for them (alkali metals and hydrogen in chalcogenides, (C2O4) 2-, (SO3) 2-).

He made a significant contribution to the general, structural and genetic mineralogy of zeolite-like silicates with mixed octahedral-tetrahedral frameworks - a new type of mineral raw material and prototypes of highly selective microporous materials with a wide range of ion-exchange, sieve, sorption and catalytic properties. Comprehensive studies of a large group of alumino-, zircono-, titanium- and niobosilicates led, on the one hand, to the establishment of the crucial role of ion exchange in postmagmatic mineralogenesis in agpaitic complexes and to the creation of a new mineralogical-geochemical and genetic concept of the development of late processes in alkaline massifs, and on the other, to the development of a scientific base for synthesis, directed chemical-structural activation and multipurpose use of a new class of promising technological materials.
