REGIONAL METAMORPHISM AND STRATIGRAPHY OF THE BASEMENT OF THE UKRAINIAN SHIELD

open access: yesGeological Journal, 2023
Stratigraphic complexes of the Lower Precambrian are everywhere metamorphosed. Therefore, the stratigraphic subdivision of the Lower Precambrian has always been inextricably linked with the study of metamorphism. For some time, the degree of metamorphism of the complexes was even used as an indication of their relative age.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Crustal velocity structure effects on the results of seismic tomography of the Ukrainian Shield

open access: yesГеофизический журнал, 2014
A model has been plotted according to average velocities in accordance with the data of seismic studies during the period from the 1960th up to the 2000th. The layered-blocky model of the earth’s crust of the Ukrainian Shield (USh) has been plotted.

Unidirectional Evaporation‐Induced Tunable and Continuous Gradient Composite Structure for Absorption‐Dominant Electromagnetic Interference Shielding

open access: yesAdvanced Science, EarlyView.
A continuous conductivity gradient is formed in a porous MXene/melamine foam via directional evaporation, thereby improving impedance matching and enhancing electromagnetic attenuation. The resulting monolithic composite delivers absorption‐dominant EMI shielding with ultralow reflection, offering a simple route toward lightweight EMI shielding ...
