Abstract
The dependence of the durability of decorative stones on its chemical weathering is described. Characterized by chemical resistance to acid solutions of labradorites from deposits of the Ukrainian shield and carbonate decorative stones to the influence of domestic pollutants. The draft methodology for investigating the chemical resistance of rocks on the example of Labradorites of the Ukrainian Shield is presented.

Keywords: weathering, durability of rocks, labradorite, carbonate natural stones, Soxhlet extractor.
