Mineralogical compounds of the composition of the dust aerosol on the period of dust storms in Tajikistan

Abstract

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).
