Pravčická brána Arch and the origin of natural sandstone arches
Cílek, Václav ; Adamovič, Jiří ; Vařilová, Zuzana
The origin of the Pravčická brána Arch was controlled by tectonic deformation of the sandstone rock massif and the formation of exfoliation scales. The present morphology is contributed by rock ledges at levels of conglomerate beds. From geological viewpoint, arches are temporary phenomena.
