This contribution presents the composition of the dust aerosol sampled during dust storms in the territory of the weather station Ayvaj, southern Tajikistan, in 2007-2015. High concentrations of the compounds quartz SiO2 (44.3%), calcite CaСO3 (17%), potassium mica KAl2([AlSi3O10](OH,F)2 (12.8%) were found. The statistical characteristics of measured compounds is determined and the correlation coefficients between certain compounds are calculated. A significant correlation is observed between quartz with albite (r=0.65), clinochlore with dolomite-2 (r=0.43), and quartz with dolomite (r=0.40).
