Stratigraphy of the dry Tetín Valley bottom sediments in the Bohemian Karst
Abstract
At the village of Tetín (SW of Prague, Bohemia) the infilling of a dry karst valley was exposed. It includes a rich malacofauna which enables the depositional sequence to be dated. Its upper part consists of loamy tufas with Holocene woodland fauna which are underlain by loess-like loams including scree intercalations with a glacial snail fauna corresponding to typical loess assemblages. A horizon of alluvial gravels documents the temporary existence of a small water stream. This evidence shows that the present day relief of the dry valley in question was formed prior to the culmination of the Last Glacial and that at certain phases a small stream occurred at its bottom as documented by gravels and tufas.
