Description Limestones with very high percentage of CaCO3 and a small amount of remaining oxides (principally SiO2 and SO3) are important industrial rocks. Vilémovice limestones (Macocha Fm.) in Mokrá quarry are widely known as best pure type not only for cement industry. However, anomalous content of sulphur above limits occurs fairly often in analyses of those limestones. Sulphur contents in limestones complicate a process of clinker firing, especially because of the increase of emissions and an absence of positive chemical reactions during the firing. The reason of their frequent occurrence in the Mokrá quarry is a hydrotermal alternation of these limestones producing the formation of sulphides (pyrite, sphalerite, galena), sheet silicates (besides Si and Al containing Fe, Mg, K) together with other hydrothermal minerals.
