Corrosion of calcite speleothems in epigenic caves of Moravian Karst (Czech Republic)
Description
The data are part of the article ‘Corrosion of calcite speleothems in epigenic caves of the Moravian Karst (Czech Republic)’ accepted for publication in the journal Environmental Earth Sciences (Springer). The results are based on a comparison of the natural corrosion of calcite speleothem with the artificial corrosion of limestone and calcite standards. A new mechanism of corrosion is presented. Conditions of corrosion are demonstrated on conceptual model of the karst vertical profile.
