The effects of air pollution and acid precipitation were investigated as causing the erosion of marble. The research indicated that the marble grains are being structurally weakened by a chemical conversion process of marble to gypsum crystals. The surface zone of chemical activity (2-5 mm) shows the presence of fly ash and iron particles, and points to the possibility of a catalytic mechanism for the conversion of sulfur dioxide to sulfate.
