    Permian to Triassic paleokarst of the Świętokrzyskie (Holy Cross) Mts, central Poland
    (Wydawnictwa AGH, 2007) Urban, Jan
    This paper presents classification of the Permian and Triassic paleokarst forms in the Świętokrzyskie Mts, systematic description of the groups of forms and their fillings as well as conclusions concerning environmental conditions of their development. Four groups were distinguished among paleokarst forms developed before the deposition of the Buntsandstein whereas five ones developed during the Buntsandstein deposition (proceeding diachronically) and/or the Middle Triassic time. The Permian-Triassic paleokarst was conditioned by the Variscan tectonic movements and up-lift as well as subsequent formation of the Danish-Polish Trough. The Permian karst developed in the area of mountainous morphology and were often connected with hydrothermal processes. The Triassic karst formed due to tectonic activity stimulating morphological rejuvenation of the region. Wide and low passages representing one of the Triassic paleokarst group presumably formed in fresh and sea waters mixing zone.
