Abstract
Natural and artificial siliceous sinter deposits actively participate in alteration of argillized rocks and in precipitation of mineral salts on the surface of geothermal deposits. The formation of extensive mass of siliceous sediments, silification and hardening of rocks enhance water-confining and heat-insulating properties of rocks, which results in practically instant (in geological time) alteration of thermodynamic parameters in separate blocks of deposits and results in formation of additional solution boiling zones. It is obvious that natural and artificial sediments of silica in a certain manner alter landscape and ecological setting in geothermal deposit areas.
