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

Melting phase relations in the MgSiO3–CaSiO3 system at 24 GPa
Progress 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
Earth, 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.

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