General review of the natural geological risks for underground constructions in the Prague Synform, with special attention to limestones and to planned high-speed railway tunnels between Praha and Beroun
Žák, Karel ; Bosák, Pavel ; Cílek, Václav ; Hladil, Jindřich ; Štorch, Petr ; Janečka, Jiří
There exist numerous natural geological risks for the planned construction of railway tunnels in the sediments of Prague Synform. These risks are related to only partial knowledge of the tectonic structure of the Synform, to frequent faulting of the rocks accompanied by zones of deep weatehring and karstification, and to the karst hydrogeology.

Vývoj krasu a jeskyní na základě studia jeskynních výplní, Slovinsko. Evolution of karst and caves based on study of cave fill, Slovenia
Pruner, Petr ; Bosák, Pavel
Palaeomagnetic method was used for a study of sedimentary fill of caves in different geological and geomorphological units of Slovenia. Sedimentary fills are substantially older than expected. The origin of cave spaces is older than 1.1 Ma.
