14C and U – series dating of speleothems in the Bohemian Paradise (Czech Republic): Retreat Rates of Sandstone Cave Walls and Implications for Cave Origin

Speleothems in 6 sandstone caves in the Bohemian Paradise (Český ráj) were dated by means of 14C and U-series methods. Sandstone caves probably intensively evolved either during or at the end of the Last Glacial period. There are two different erosion mechanisms: repeated freeze/melt cycles and seep...

Description
Summary:Speleothems in 6 sandstone caves in the Bohemian Paradise (Český ráj) were dated by means of 14C and U-series methods. Sandstone caves probably intensively evolved either during or at the end of the Last Glacial period. There are two different erosion mechanisms: repeated freeze/melt cycles and seepage erosion of sandstone during the melting of permafrost.
