dc.abstract.en For a long time, salt weathering was a dominant process of rock decay in polluted atmosphere in Kraków. Weathering zones developed on the Middle Triassic dolomite surfaces exposed to direct rain-washing and sheltered from rain were studied in order to discuss the influence of exposure conditions on the mechanism of weathering. Optical microscopy, scanning electron microscope with energy dispersive spectrometer, and X-ray diffraction were used. On the walls exposed to rain, fragments exposed to intensive washing by rainwater are bright and devoid of secondary minerals. Less intensively washed surfaces are covered by a black brittle gypsum-rich crust. On the surface of the sheltered walls a dark grey crust has developed. It is composed of loosely packed agglomerations of platy gypsum crystals with abundant dust particles. Crystallisation of gypsum from rainwater and reactions of sulphur-containing components from the rainwater with Ca ion from the rock are important in the formation of black gypsum crust. The deposition of dust particles and adsorption of sulphur-containing components are the most important factors in the grey crust formation. pl
