Nové objevy v Petzoldových jeskyních v Českém krasu
Cryogenic cave carbonates (CCC) are formed in caves during freezing of calcium bicarbonate water by expulsion of the dissolved load in form of carbonate crystals. Fine-grained (powder) CCC types are formed in recently iced caves by freezing of a thin water layer on the surface of ice. Coarse-grained...
