Reconstruction of the Development History of Karstic Water Networks on the Southern Part of the Gömör-Torna Karst on the Basis of Ruined Caves and Landforms

Abstract

Avtor razlaga razvoj kraskega povrsja Gomor-Torna2 (na madžarsko-slovaski meji) od terciarja do danes. Na planoti je mogoce slediti razvoju od pokritega do odprtega (golega) krasa in vpliv procesov zakrasevanja na povrsinske oblike in na smer podzemeljskega odtoka. Avtor je preucil razvoj povrsja in podzemeljske vodne mreže ter na podlagi morfoloskih oblik, ki jih je izdelala voda, ugotovil enakomerno zniževanje vodnih tokov. Opirajoc se na skromne ostanke epigenih dolin, ki so bile tako v sedimentnem pokrovu kot v samem apnencu, na sledi nekdanjih ponorov v dnu dolin in na opuscene podzemeljske prevodnike (jame) iz zgodnejsih faz razvoja, je avtor rekonstruiral smeri odtoka z obravnavanega pokritega krasa. The author demonstrates the surface development of the Gomor-Torna karst2 situated on the Hungarian- Slovakian border from the Tertiary until the present day. He follows the process of transition from the covered karst conditions to the open karst on the karst plateau, and its effect upon the landforms and the karstic water network. He studied the evolution of surface and sub-surface water networks, and the regularity of the movements of underground rivers based on water tracing. He reconstructed the ancient surface outflow directions of the covered karst from the scarce remains of the epigenetic valleys inherited from cover deposits onto the limestone surface, from ruined swallow hole lines in valleys, as well as from decaying water conducting tubes generated in earlier phases.
