    Schlagwort(e): karst ; distribution of karst ; earth crust ; hydrosphere ; vertical zoning ; hypogenic karst
    Beschreibung / Inhaltsverzeichnis: Some problems of theoretical karstology are considered. An attempt is made to match the fundamentals of karstology and recent ideas on the structure of lithosphere and the vertical zoning of hydrosphere. Boundary conditions of karstogenesis and karst zoning are discussed. The boundaries and the structure of karstosphere, as well as the place of karst among other geological processes are defined.

    Beschreibung / Inhaltsverzeichnis: In this book geological the conditions of speleogenesis in the Miocene gypsum in the Western Ukraine are characterized, particularly the role of lithological and structural prerequisites in speleogenesis. The special attention is given to structural and textural unhomogeneities in the gypsum stratum and to their role in the formation of fractures. Fracture systems in the gypsum and the structure of the unique maze cave systems are examined in details. It is shown that speleo-initiating fractures in the gypsum strata belong to the lithogenetic type and form largely independent multi-storey networks, with each storey being confined within a certain vertical structural/textural zone (unit) of the stratum. This determines the multi-storey structure of the caves in the region. Two problems related to structural and textural characteristics of the gypsum stratum are discussed in details: the formation of giant dome structures by way of gypsum recrystallization during the synsedimentary and early diagenesis stages, and the genesis of fractures. Speleogenetic realization of the existing structural prerequisites occurred under conditions of a confined multi-storey artesian aquifer system due to an upward flow across the gypsum from the under-gypsum aquifer.

    Beschreibung / Inhaltsverzeichnis: Preface Karst phenomena consist mainly in dissolving of rock by water, with subsequent formation of underground voids. Studies on karst and caves are of extremely nterdisciplinary character; they are within the scope of interest of all the disciplines of earth sciences. Since caves provide permanent habitats or temporary shelter to many organisms including Palaeolithic man, they are of interest to biologists and archaeologists. Because of its glacial history and geological structure, southern Poland offers a good opportunity to study all the karst-related phenomena. It holds two main, geographically remote karst areas of much different landscape: the Kraków- Częstochowa Upland and the Eastern Sudetes. Their caves are filled with sediments which document various phases of karst development in Poland, including Pleistocene glaciations, as well as changes in palaeoenvironments and faunal evolution. Many contain traces of occupancy by Palaeolithic man; the archaeological record found in some of them extends to modern times. The special significance of caves and karst areas – often the only places where traces of fossil environments and human occupancy are preserved – in Poland was recognised more than 150 years ago. Modern speleological studies in karst areas of Poland started in the 1940s with the wide ranging research of Kazimierz Kowalski - the inventory of caves and review of earlier studies (Kowalski K. 1951 & 1954 – Jaskinie Polski, Vol. 1-3). They triggered comprehensive and interdisciplinary cave studies by representatives of various disciplines. Much progress was made during the last twenty years. Numerous new caves were explored and studied with modern methods; cave sediments containing numerous faunal remains and artifacts were discovered, and earlier information on environmental changes and history of human occupancy could be verified. Despite the long-term and extensive research and exploration, either the studies in the Kraków-Częstochowa Upland nor those in the Eastern Sudetes were ever summarised. The data, though abundant, are scattered among many sources, mostly associated with particular scientific disciplines. This volume is an attempt at a comprehensive summary of the information on karst and karst-related phenomena in these two regions. Since the 1950s many scientists have contributed enormously to the knowledge of various aspects of karst-related phenomena in Poland. Some of these pioneers of interdisciplinary karst studies have departed recently: Waldemar Chmielewski (archaeologist), Jerzy Głazek (geologist, speleologist), Kazimierz Kowalski (pa-laeontologist, speleologist), Stefan Kozłowski (geologist), Marian Pulina (geomorphologist, speleologist) and Teresa Wiszniowska (palaeontologist, speleologist). Thanks to their great passion and commitment, the interest in caves and karst of the Kraków-Częstochowa-Upland and Eastern Sudetes in the last fifty years has considerably increased.
