Abstract (in english)
   The most conspicuous examples illustrating ascending (per ascensum) speleogenesis linked with deep faults/fault systems from Slovakia and Czech Republic are presented. In the past, the caves have been described as product of phreatic, epiphreatic and vadose speleogenesis related to the evolution of local water courses and valley incision, and linked mostly with Pleistocene geomorphic evolution.
   All studied caves developed along or in close vicinity of deep faults/fault zones, commonly of regional importance; the groundwater ascended due to deep faults/fault systems mostly as results of deep regional circulation of meteoric waters from adjacent karst or nonkarst areas; the 3D mazes and labyrinths dominate in cave morphology; speleogens indicate ascending speleogenesis in deep phreatic to phreatic environments; caves exhibit poor relation to the present landscape; in some of them fluvial sediments are completely missing in spite of surface rivers/streams in the direct vicinity; strong epiphreatic re-modelling is common and related to the evolution of the recent landscape; recharge structures and correlate surface precipitates are poorly preserved or completely missing (denuded) on the present surface in spite of fact that recent recharges broadly precipitate travertines; caves can be, and some of them are, substantially older than the recent landscape (Pliocene, Miocene), and c
   av
   es were formed in conditions of slow water ascent, which differentiate the process from faster vauclusian ascending speleogenetical models. Any of described caves contains clear diagnostic features of real hypogene caves. Any of described caves cannot be directly characterized as product of thermal waters or hydrothermal process (i.e. as real hyperkarst), therefore they do not represent hypogenic caves.
