The Mutnov geothermal field is of the solfatara type (H/sub 2/S-CO/sub 2/ hot springs of surface origin), similar to the Geysers in California and Matsukawa in Japan, as well as Nizhnyy Koshelev in Kamchatka. These fields are characteristic of high-temperature hydrothermal systems in regions of current volcanism, the natural results being sulfur-ammonium boiling springs and fumaroles. Drilling has shown such hydrothermal systems to be vapor-dominated at depth. Drilling at the Mutnov field has allowed examination of the section down to a depth of approx. 1.5 km. The results are important for understanding underlying processes, particularly because very few vapor-dominated systems have been studied. This paper proposes a genetic model for the Mutnov geothermal area in Kamchatka. Vertical changes in the P-T and chemical characteristics of the thermal waters, and in the nature of hydrothermal alteration, suggest a genetic link with some epithermal ore deposits. 30 references.
