Results of study of mineral composition of Uskol lake bottom sediments are given in the present work. Uskol lake is located on the territory of Uybatskaya steppe, South-Minusinsk basin. These are modern alluvial-deluvial sediments mostly consisting of clays and silts. Presence of such mixed-layer compounds as rectorite, Na-monmorillonite-Na-mica, swelling chlorites at the studied object was stated the first time. Regularity of clay minerals distribution through the section was observed. It’s importance is conditioned by clay minerals ability to serve as indicators of paleoclimate and environmental conditions of sediments formation in the region. Bottom sediments mineral composition was defined: clay minerals, zeolite (analcime), quartz, feldspars, calcite, gypsum, halite.
