Abstract
This special issue of the Geology and Geophysics contains articles presented in the wake of the scientific conference "High-Pressure Mineral Formation Processes: The Origin of Diamonds and Mantle Magmas," dedicated to the 90th anniversary of the birth of the outstanding researcher of diamond formation, Academician Nikolai Vladimirovich Sobolev. The conference took place from June 17–19, 2025, in the Novosibirsk Akademgorodok at the V.S. Sobolev Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy of Sciences. The range of topics covered, from detailed studies of crystal structure defects in individual diamonds and inclusions in it to the regimes and timing of plate tectonics on the early Earth, fully reflects N.V. Sobolev's contribution to the formation of modern understanding of the evolution of the Earth's mantle composition and the formation settings of kimberlites and diamonds.
