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.

The Tatras - nappes and landscapes
(Wydawnictwa AGH, 2008) Felisiak, Ireneusz
Geological structure of the Tatra Mts is a result of long-lasting processes. The key nappes have already been completed some 65 Ma ago. However as a mountain range the Tatras has emerged at the surface only 5 Ma ago, when a piece of continental crust separated from African continent at the beginning of Mesozoic era ultimately collided with Europe. Thus, the crystalline core of the Tatras, which builts also the highest crest is a fragment of Africa. This monumental mountains are, however, not an effect of the overthrusting but they resulted from young, vertical tectonic movements, which are still active and which sometimes shake the whole Podhale region. The following paper explains how the Tatras were formed. The figures enclosed illustrate the succeeding formation stages of the mountain range and the photographs allow the Reader to compare drawings with the field. Welcome to the Tatras.
