Polygon “Simeiz-Katsively” - changes in the average pole of the Earth and the geomagnetic field over the last century [PDF]

open access: yesITM Web of Conferences, 2019
The character of changing the trajectory of the middle of the North geographical pole of the Earth's surface over the last century is studied. The peculiarities in the changes of its coordinates are established.

Melting temperatures of MgO under high pressure by micro-texture analysis

open access: yesNature Communications, 2017
Melting behaviour of MgO under pressure remains unclear despite the importance of constraining the rheology and composition of the Earth’s mantle. Here, the authors show that melting temperatures in earlier static experiments were underestimated based on

Polygon “Simeiz-Katsively” - the cycles in the climatic and the geophysical characteristics of the Crimea [PDF]

open access: yesITM Web of Conferences, 2019
Coherent variations are established with periods of about 10–12 years and 60–70 years, which are found in processes of different physical nature and can be attributed to global cycles in the solar system, the manifestation of which in climatic and ...

Melting phase relations in the MgSiO3–CaSiO3 system at 24 GPa

open access: yesProgress in Earth and Planetary Science, 2017
The Earth’s lower mantle is composed of bridgmanite, ferropericlase, and CaSiO3-rich perovskite. The melting phase relations between each component are key to understanding the melting of the Earth’s lower mantle and the crystallization of the deep magma

Core surface sub-centennial magnetic flux patches: characteristics and evolution

open access: yesEarth, Planets and Space, 2017
Short-term constituents of the secular variation, at inter-decadal (20–30 years) and sub-centennial (60–90 years) time scales, present in observatory data and main field models, are also found in the radial field evolution at core surface.

GEODYNAMICS [PDF]

open access: yesGEODYNAMICS, 2018
Purpose. The paper substantiates the need for building seismic zoning maps of Kyiv in the physical parameters of ground motions: peak ground accelerations (PGA), peak ground velocities (PGV) or peak ground displacements (PGD), which are the basis for the effective use of methods for calculating seismic loads on buildings, structures and individual ...
