Реферат:	eng: 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 O-18 in ore-bearing quartz range from +4.89 to +9.59 parts per thousand, which corresponds to a hydrous fluid of magmatic origin. This is supported by the sulfur isotope composition of sulfides (S-34 from 07 to 6.7 parts per thousand) corresponding to the hydrothermal orogenic deposits.
