Abstract
Secondary carbonates in 4 sandstone caves in the Bohemian Paradise were dated by means of 14C and U/Th methods. Secondary carbonates (cave sinters) were deposited 5-13 kyr BP. Stable isotope values of C and O of carbonates from Krtola and Petráskova caves fall into values typical for cave sinters. In Sintrová and U studánky caves the isotope composition indicates evaporation and fast CO2 degassing. Secondary carbonate deposits proved that sides of studied caves were not enlarged for at least last 5-8 kyr BP. Caves were thus created probably during last glacial or at glacial/Holocene transition.
