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 percolation; percolation water is 1. ground water moving slowly through the microfissure network of a limestone, most of which eventually joins a major cave conduit and flows more rapidly. in most environments percolation water enters the limestone through a soil cover. it is therefore high in carbon dioxide and has a major influence on limestone dissolution and later redeposition of calcite speleothems. percolation water accounts for most of the storage in a limestone aquifer, responds slowly to flooding in comparison to sinkhole water, and is normally of high enough quality to provide a drinking-water supply [9]. 2. the movement in laminar flow under hydrostatic pressure of water through the interconnected, saturated interstices of rock or soil, excluding movement through large openings such as caves and solution channels. 3. the downward movement of water through the unsaturated zone [22]. 4.the downward flow of water in saturated or nearly saturated porous medium at hydraulic gradients of the order of 1.0 or less [22]. 5. the movement of water through saturated interior pore space [16]. synonym: seepage water.?

The DIAU SYSTEM - Diau Cave is the resurgence of an important underground drainage system in the massif des Bornes in Haute-Savoie (France). The system's catchment is approximately 9km2, between an altitude of 1200m and 1800m. The average discharge is about 4001/s. Speleological explorations have discovered two sections of the master drainage cave (Diau and Pertuis caves). Two tributaries have also been explored. The total length of the Diau cave system is 14.9km with a height difference of 702m. The master cave occurs in the bottom of the Pertuis syncline at the boundary between the urgonian limestone and hauterivian marls. According to the gradient and the fractures, four types of gallery structure occur, of which two are vadose. The two known tributaries (inlet of the Grenoblois and Tanne des Météores) follow a NW-SE anticlockwise shear fault, which exists in the Parmelan plateau fracture zone.
THE MASSIF OF PARMELAN, HAUTE-SAVOIE, FRANCE: RELATIONS BETWEEN FRACTURATION AND KARSTIFICATION - The massif of Parmelan (Haute-Savoie), encloses a well-karstified and highly organised perched aquifer. Its simple geological structure and easy-speleological penetration (more than 45km are known) have allowed a statistical study of the fracturation and karstification parameters at different scales. This study shows that the karst has developed on the most frequent fracturation directions (study of the cumulated lengths), whereas its directional distribution in frequency is relatively homogeneous; the most used fractures are the tension faults, linked with the folding of the massif.
