N2 - The Lyubavinskoe gold deposit is controlled by the submeridional deep tectonic zone. In this zone, ore veins closely associate with small Mesozoic granodiorite stocks, porphyry diorite, and lamprophyre dykes with a predominant sublatitudinal orientation. According to the geochemical patterns, these intrusions are similar to adakite. The proportion of the oxygen and strontium isotopes in granodiorite provides evidence for their formation as a result of the processes of mantle–crust interaction. The calculated values of δ18OH2O in ore-bearing quartz range from +4.89 to +9.59‰, which corresponds to a hydrous fluid of magmatic origin. This is supported by the sulfur isotope composition of sulfides (δ34S from 07 to 6.7‰) corresponding to the hydrothermal orogenic deposits.
