NON-KARSTIC SPELEOGENESIS IN SANDSTONE ROCKS OF UKRAINIAN CARPATHIANS

Due to the limited distribution of karst rocks and, accordingly, small number caves in Ukrainian Carpathians, non-karst (pseudokarst, clastokarst) genesis attract considerable attention from cave researchers. The latter most often develop massive and coarse-grained sandstone strata, usually found as part flysch strata. non-karstic are widely spread Cretaceous Paleogene formations Carpathians. Most them developed Yamna Formation Palaeocene. primary information about all on territory Ukraine is collected by Commission for Accounting Documentation Caves Speleological Association (UkrSA), local caving clubs individual Currently, discovered Carpathians exceeds mapped caves, not mention their detailed description. minimal each cavity includes name, entrance coordinates, total length, depth (amplitude) resulting survey. additional description could contain knowledge history discovery, origin, geological settings, microclimate, sediments, inhabitants, paleontological archaeological remains, etc. At present, many have been a few microregions: Kliuch Ridge, near Skole; tract Drybka, between Yaremche Yamna; Sokilsky its south-eastern orographic continuation at tracts Protiate Kaminnia Lekeche; Polonyna Runna; Lubnia Village; Chorna Gora Ridge. Few yet cavities known Bubnyshche, Synytsia Mt., some other sites. belong three genetic types: tectonic, gravitational, selective corrosion. largest among tectonic Tectonic (Dovbush) Village, which 388 m long. longest selective-corrosion 92 Some with fissure-like morphology also be cryogenic origin. We suggest that forms paleoseismic dislocations. Keywords: sandstone; pseudokarst; speleogenesis; corrosion;
