Abstract
This special issue of the journal Russian Geology and Geophysics comprises studies presented in the wake of the scientific conference “Processes of mineral formation at high pressures: the origin of diamond and mantle magmas”, dedicated to the 90th anniversary of the birth of the outstanding researcher of diamond formation processes, Academician Nikolai Vladimirovich Sobolev. The conference was held on June 17-19, 2025, at the V.S. Sobolev Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy of Sciences, in Novosibirsk Akademgorodok. The range of topics addressed, from detailed studies of crystal lattice defects in individual diamond crystals and their inclusions to the regimes and timing of the plate tectonics on the early Earth, fully reflects N.V. Sobolev’s contribution to the formation of our modern understanding of the evolution of the Earth’s mantle composition and the formation settings of kimberlites and diamonds.
