(VavĜinec occasionally observed falling of straw stalactites Lmst., Josefov Lmst., Lažánky Lmst. and in the Moravian Karst caves is caused by a Vilémovice Lmst.) and the LíšeĖ Fmt. (KĜtiny hypothetical chemical corrosion. The straw Lmst., Hády-ěíþka Lmst.). Total thickness of the stalactite wall was found to be formed by three carbonate rocks has been estimated as 500–1000 m. calcite layers. The middle layer (a stalactite The overwhelming majority of caves were formed skeleton) was typically cracked in agreement in the Vilémovice Lmst. The largest cave system in with calcite cleavage. Some impact of chemical the Moravian Karst is the system called the corrosion was positively identified on the outer Amatérská Cave (over 15 km of corridors). At side of straw stalactite walls. Any corrosion of present four caves in the Moravian Karst are open the inner wall of stalactite channel was not to the public – the Punkevní Caves, Sloupsko- explicitly proved. This is consistent with the ŠošĤvské Caves, KateĜinská Cave and Balcarka supersaturation of the majority of monitored Cave. With their unique dripstone decoration, they dripping waters with respect to calcite (SI=0.2 to belong to the most impressive caves in the Central 1.2). However, the finding of unsaturated Europe. Recently, however, some destruction dripping water in the Punkevní Caves (SI=-0.8 processes, in which a falling of straw stalactites to -0.3) did not allow to exclude the chemical dominates, are observed in all caves of the corrosion definitively. The seasonal increase of Moravian Karst. A hypothesis is suggested that cave CO2-concentrations (up to 1 vol. %) was some chemical corrosion reduces the stalactite wall consistent with increasing number of visitors (up at “a stalactite neck”, which leads to stalactite to 28 000 per month in the Punkevní Caves) and destabilization and consequent falling. The goal of with the CO2-production in the soils above caves this work was to decide whether such corrosion (up to 1 vol. % in soil atmosphere in Summer). really operates in the caves. The drop of the cave CO2-concentrations in Fall and Winter roughly corresponds to the decrease 2. METHODS of the soil CO2-concentration, visitor number, and probably also to change in cave ventilation.

Selected straw stalactites dripping water, fissures, straw stalactite, were corroded in laboratory by 0.1 mol l-1 HCl supersaturation flowing continuously through the stalactite channel and consecutively studied by former methods. 1. INTRODUCTION Dripping waters in the Punkevní Caves, Balcarka The Moravian Karst is the biggest and the most Cave, and Amatérská Cave were studied during important karst area of the Bohemian Massif. It is year 2003. pH (combined glass electrode, pH-meter located north of Brno, making part of the Drahany WTW pH 330i), calcium (complexometric Highlands area. Its rocks crop out on the area of 94 microtitration, 0.01 mol l-1 EDTA, 10 % KOH, km2 as a belt 3-5 km wide and 25 km long.
