Аннотация
This paper presents the results of multiannual complex geochemical and geophysical studies of a caldera of Golovnin Volcano. The peculiarities of the chemical composition of thermal fluids and condensates are discussed. Geophysical sections including discharge zones of active gas hydrotherms are interpreted regarding the formation of the chemical composition of fumarolic gases and thermal fluids. The selection of the quantitative compositions of interacting milieus and the physicochemical models are based on the data. The most likely physicochemical conditions of the ascending fluid to the surface are suggested on the basis of models and the results of the study of the subsurface space of the thermal fields.
