Аннотация:The features of the transformation of andesites of the East Pauzhetka thermal field under the influenceof the argillization process are studied based on a number of samples with different degrees of alteration, which were taken from boreholes and outcrops near the study object. The main patterns of changes in the composition and physical and mechanical properties of andesites have been revealed. A schematic diagram of the structure of the thermal field in section has been compiled; this diagram distinguishes three horizons from bottom to top, showing an increase in the degree of hydrothermal transformation: altered andesites, metasomatic breccias, and hydrothermal clays.
