Hello everyone!
I pleased to invite you to the official site of Central Asian Karstic-Speleological commission ("Kaspeko")
There, we regularly publish reports about our expeditions, articles and reports on speleotopics, lecture course for instructors, photos etc. ...
Dear Colleagues, This is to draw your attention to several recent publications added to KarstBase, relevant to hypogenic karst/speleogenesis: Corrosion of limestone tablets in sulfidic ground-water: measurements and speleogenetic implications Galdenzi,
A recent publication of Spanish researchers describes the biology of Krubera Cave, including the deepest terrestrial animal ever found:
Jordana, Rafael; Baquero, Enrique; Reboleira, Sofía and Sendra, Alberto. ...
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 resurgence is 1. re-emergence of karst ground water a part or all of whose waters are derived from surface inflow into ponors at higher levels [20]. point at which an underground stream reaches the surface and becomes a surface stream. in european literature, the term is reserved for the re-emergence of a stream that has earlier sunk upstream; the term exsurgence is applied to a stream without known surface headwaters [10]. synonyms: (french.) resurgence; (german.) karstquelle; (greek.) kephalari; (italian.) risorgenza; (russian.) vyhod karstovyh vod; (spanish.) resurgencia; (turkish.) sucikan; (yugoslavian.) krski izvor (vrelo), obrh. see emergence. compare exsurgence.?
In the valleys of southeastern France, below karst massifs, river deposits with travertines show vertical sedimentary sequences always similar, with, from bottom to top: gravels, silts, chalks, travertines s.s. (stromatolitic encrustations with laminated facies), travertinous sand, silts. The study of flora and fauna fossilized by these formations shows a good correlation between the maximum of carbonate deposition (travertinous facies s.s.) and the optimum of vegetation development (forest). And finally, behind calcareous dams edified by travertine, paludal and lacustrine fields are environments developed trapping diversified sediments (clays, peats, silts,...). Then, dam and lake are forming a unit that we can call a 'travertine system'
