C-14 AND U-SERIES DATING OF SPELEOTHEMS IN THE BOHEMIAN PARADISE (CZECH REPUBLIC): RETREAT RATES OF SANDSTONE CAVE WALLS AND IMPLICATIONS FOR CAVE ORIGIN

Popis výsledku v původním jazyce

Speleothems in 6 sandstone caves in the Bohemian Paradise (Cesky raj) were dated by means of C-14 and U-series methods. Stable isotopes of C and O, FAAS, IR, XRD, XRF and SEM were used to characterize the carbonate material and its source. Stable isotopes (C and O) composition of speleothems in two caves corresponds to values characteristic for cave speleothems in Central Europe. In other caves they indicate evaporation and fast carbon dioxide escape during carbonate precipitation. The speleothems fromthe Krtola Cave were deposited between 8 and 13 kyr BP. Speleothems were deposited 5-8 kyr BP in the Sintrova, Mrtve Udoli and U Studanky caves. Calcite coatings on smooth sandstone surfaces in studied caves demonstrate that cave walls did not retreat even a few mm in the last 5-8 kyr since speleothem deposition and are thus not evolving under recent climatic conditions. Most of the cave ceilings and walls are at present time indurated by hardened surfaces, which protect the sandstone fr
