Geoelectric parameters of the northwestern part of the Ukrainian Shield from 2D inversion

open access: yesГеофизический журнал, 2020
Based on a 2D inversion of magnetotelluric data along six meridional profiles traversing the northwestern part of the Ukrainian shield, local objects of reduced resistivity (with ρ < 100 Ohm · m) in the Earth's crust and upper mantle are identified.

Plate-tectonic metallogeny Ural-Timan-Paleoasian segment of the Eurasia on the base of mobilistic reconstructions

open access: yesЛитосфера, 2017
General positions on plate-tectonic metallogeny are presented and the grounds for singling out the metallogenic factors of orogenic systems are given. Mobilistic paradigma corresponds to the genotype of orogens and belts which being formed at the expense

Geodynamicsand metallogenyof the Keivy domain (Baltic Shield)

open access: yesVestnik MGTU, 2020
Geodynamic and petrogeochemical study of the Keivy domain in the Baltic Shield has shown that it was overlapped by surrounding microcontinents in the Archean. As a result, the Baltic Shield was subject to cratonization. Thus, the Keivy microcontinent can
