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

Geodynamicsand metallogenyof the Keivy domain (Baltic Shield)
Vestnik 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
