TECHNOGENIC COMPONENT OF MODERN AEOLIAN
SEDIMENTOGENESIS (USING THE EXAMPLE
OF THE KRYVYI RIH IRON ORE BASIN OF UKRAINE)

Studies of atmospheric dust in the south of the Kryvyi Rih Iron Ore Basin of Ukraine were carried out.
The granulometric, chemical, and mineral composition of dust particles retained on filter fabric by the
ASA-4M aspirator was determined. It was established that the dominant sizes of ore and silicate particles
retained by the filter are –50+40 -m and —2.5+0 -m. The shape of the dust particles is irregular (magnetite, quartz, goethite) or flaky (iron mica, muscovite, biotite). A wide range of chemical compounds was found in the dust samples. The most common among them are Fe2O3, FeO, and SiO2. It has been established that fragments of magnetite, hematite, goethite, biotite, cummingtonite, muscovite, actinolite, quartz, calcite, siderite, and kaolinite-originating from dumps and tailings of the mining and quarrying industry-participate in aeolian processes in the south of the Kryvyi Rih Iron Ore Basin.
