Caves - landscapes without light

Exhibition dedicated to caves is taking place in the Vienna Natural History Museum   The exhibition at the Natural History Museum presents the surprising variety of caves and cave formations such as stalactites and various crystals. ...

That stalactite is 1. speleothem, generally of calcite, formed by dripping water and hanging from a cave roof. stalactites embrace an enormous variety of sizes and shapes. they form where percolation water seeps from a cave ceiling and becomes saturated with respect to calcite due to loss of carbon dioxide into the cave air. calcite is precipitated round the rim of the water droplet and continued deposition creates a hollow tubular straw stalactite (soda straw). additional deposition of calcite on the outside of the initial cylinder creates an ordinary tapering stalactite. almost infinite variation in shape may be influenced by changes in water flow, cave air chemistry, evaporation, temperature or dissolved impurities, and by crystal growth blocking flow paths. they are the most common speleothem. though the single 7m long stalactite in ireland's poll an ionain is not the world's longest, it is uniquely spectacular against the dark chamber walls [9]. 2. conical deposit of calcite or aragonite often with a hollow center hanging from the roof of a cave or cavern formed by precipitation of carbonate due to escape of co2 from hanging water beads and to evaporation of part of the water [20]. 3. a cylindrical or conical deposit of minerals, generally calcite, formed by dripping water, hanging from the roof of a cave, generally having a hollow tube at its center. from greek word meaning exude drops [10]. synonyms: (french.) stalactite; (german.) tropfstein, stalaktit; (greek.) stalaktitis; (italian.) stalattite; (russian.) stalaktit; (spanish.) estalactita; (turkish.) sarkit (yugoslavian.) mosur, viseci kapnik, stalaktit.?

L’utilisation des réserves hydrauliques karstiques : l’exemple de la commune de Penne-de-Tarn
Abstract:
Water collecting in the commune of Penne was meant to offer an option to the polluted and scarce water resources of the liasic limestone aquifer layer through a planned and reasonable exploitation of the Jurassic reserves. Three underground streams actually supply the whole commune territory - the largest in the Tarn department - with good water which does not suffer any summer depletion. The civil engineering work, the electro-mechanical fittings, the proper fixtures which followed the preliminary surveys were made by unpaid amateur cavers from several clubs of the caving district committee gathered in the ATEK (Association Tarnaise d'Etudes Karstiques). Different methods and techniques have been used to collect water on the following three sites: - the underground stream of Cabeou and the building of a storage dam of 500 m3 which was put into service in 1984 on the limestone plateau of the Garrigue; - the undergroung stream of Amiel where a 25 meter deep well was drilled through hard rock and which has supplied the village with water since 1985; - and the underground stream of Madeleine whose pumping station protected by a dam has increased the water resources of the right bank of the Aveyron river since 1989.
