The paper presents the locally variable impacts of hydrothermal processes and provides explanations for the hydrothermal karst in the mountains. According to the A. neither dripstone formation, nor the major cave systems carved out by the mechanical
erosion of streams can be excluded from among karst phenomena. Author regards the Buda Hills (Hungary) a prototype of hydrothermal karst. - (JS)

The surface of the Gömör–Torna/Gemer–Turňa Karst was largely formed by Pannonian or Pliocene pediplanation. Although this surface has been dissected by subsequent tectonic and fluvial processes, the present karst plateaus still preserve large pieces

The Cockpit Country is the type area for cockpit karst landforms. A detailed analysis of cockpit karst terrain is carried out using the latest GIS-based digital morphometric techniques in order to assess the nature of such terrain and provide
further information for subsequent modelling, as well as other non-geomorphological applications, such as environmental management and conservation issues. The results indicate that cockpit karst may be categorized based on its vertical, horizontal

Surface karst is believed to influence the qualitative and quantitative characterisric of the waters that feed aquifers. This paper focuses on the morphometry of some surface karst features and on their relations with groundwater resource

Actuellement les recherches sur le développement du karst mettent également l'accent sur l'influence de l'activité humaine sur le système karstique. L'étude du système karstique écologique est complexe. L'A. en donne un schema et prend pour exemple
The newly discovered cave system of the Punkva River in the Moravian Karst offered favourable conditions for the study of its relations to the environment. The Amateur Cave belongs to the longest in Europe and enables to complete the hydrogeological
knowledge about the water circulation, tectonics, paleontology, biospeleology, etc., of Moravia Karst. (MS).
Tableau synthétique des principales unités karstiques et de leurs problèmes. La grande variété des karsts est en relation avec plusieurs variables, telles que les données lithostructurales, morphoclimatiques et paléo-karstiques. Les processus
hérités sont définis en rapport étroit avec les sédiments corrélatifs épiclastiques et les tufs calcaires et autres concrétions endo-karstiques dépendant des systèmes successifs.

the relative contribution of a major cave system to a preliminary sediment budget for a karst watershed.
This paper presents a preliminary assessment of fluvial sediment storage and yield in an urbanized, karst watershed. The AA. aim to identify and quantify the function of caves and sinkholes within the context of a sediment budget with 3 specific

In this paper an overview on recent research on karst waters in Slovenia is presented. In recent years a great emphasis was given to the investigation of water flow and transport in karst aquifers and questions regarding the protection of karst
) and the Chalk dissolution products of all local stratigraphic levels. Based on these microgranulometric spectra, they propose a conceptual model for processes occurring in chalk karsts and a classification scheme for karstified systems according to how
such systems deal with particles. In a closed karst, the suspended matter tends to come from the Chalk itself, while in the case of an open karst, the majority of suspended particles comes from surface formations.
The AA. have studied the chalk karsts of Haute Normandie by comparing microgranulometric spectra of suspended matter (SM), in subterranean waters and in solutions of the main surface formations (Clay-with-Flints Complex (CFC) and loess

The AA. report here the results of a study of the mineralogy and geochemistry of a suite of sediments from the Castle karstsystem, Derbyshire, England. They use these data to constrain sources of sediment in different parts of the system
Karstified Middle Miocene sediments are widely exposed in northern Iraq particularly in the area surrounding the city of Mosul. 2 karstsystems were identified, an active and recent system characteristic of all the anticlinal structures and an older
(Pleistocene) fossil karstsystem characteristic of Alan, Ishkaft, Albu Saif and Hammam structures. The fossil karstsystem is preserved on remnant elevated old land surfaces and produces characteristic tight undulations in the limestone due to collapse inwards
in sinkholes and elongated tunnels formed along a series of sinkholes. Karst areas are related to densely fractured areas.

A la frontière belgo-néerlandaise, des carrières creusées dans des calcarénites et des craies crétacées recoupent de nombreux karsts ainsi que des noyaux profonds de roches altérées. Leur étude permet de reconstituer la genèse d'un système karstique
anciens et organisent des systèmes complexes d'écoulement au sein des craies.
