Abstract (in english)
   The Arnoldka Cave (1 250 m long, -111 m) is situated in the central part of the Bohemian Karst in the Čeřinka Quarry. At least 4 evolution stages can be distinguished in all cave systems of the quarry. (1) Inclined passages developedfirst in the phreatic conditions along intersections of tectonic lines and bedding planes. Pasages follow the strata dip. Caves are developed in a "colector" of Pragian limestones confined inbetween more impremeable strata. (2) The phreatic system was later modified by the corrosion along the water tables with the formation of bevels (Laugdecken). (3) The cavities were later filled with thick sequences of sediments. Ceiling half tubes (meanders) formed in places. Agressive waters changed limestones to white pulverized beds. (4) Cave sediments were most probably during Quaternary, exhumed and transported down to lower positioned cavities owing to increased hydraulic gradient. The process has been still active
