Tree-Mould Caves In Slovakia, Ludovít Gaál Jan 2003

Tree-Mould Caves In Slovakia, Ludovít Gaál

International Journal of Speleology

Four tube-shaped caves are described in this work, which origined in consequence of weathering the trees. Their length ranges from 5.8 to 17 m. All of them occur in neovolcanic rocks of Middle Slovakia, in epiclastic andesite conglomerates, breccias or in the tuffs. Some other caverns are close to the entrance of this caves, however they are inaccessible for a man. Thin rim of silicates (opal or chalcedony) occurs in some of them.
