Diagenetic history of the Podhale flysch basin
(Wydawnictwa AGH, 2008) Środoń, Jan
This text presents a one day field trip starting and ending in Zakopane, Poland, devoted to explaining geological history of the Tertiary flysch basin of Podhale, situated between the Tatra Mts. and the Pieniny Klippen Belt. The first stop demonstrates the rocks filling the Podhale Basin: sandstones, shales, and in particular bentonites, which are rare horizons of volcanoclastic origin, helpful in radiometric dating of the basin maximum burial. From the top od Wżar Hill (second geological stop), which itself is interesting from geoturistic standpoint for the quarries exposing its andesite sills, the topography of Podhale and Spišská Magura, which reflects higher rates of uplift in the east, is clearly visible. The flysch basin, which developed in Eocene, and in Oligocene covered entire region including the Tatra Mts., formed due to vertical down movement on the Ružbachy fault, and then, ca. 15-18 Ma ago was inverted and uplifted, again along the Ružbachy fault. The fault itself and the accompanying phenomena (thermal water discharge and travertine deposits) are visited at the final stop in Vyšné Ružbachy.
