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. ...
Did you know?

The formation of the Oligocene « calcaires à Astéries » in the region of « Entre-deux-Mers » is affected by a karstification with subhorizontal caves that drained rivers from swallow-holes to resurgences. Observations in quarries show that ghost-rock alterites are present. This paper describes the ghost-rocks in the quarry of Piquepoche exploiting the Frontenac stone. We have studied horizontally developed ghost-rocks with vertical extensions still containing the residual alterite. They can be badly consolidated calcarenites up to soft material which has been sampled. Speleogenesis is reviewed in the frame of the mechanical erosion of the alterite of a horizontal ghost-rock followed by an incision by free-flowing waters which form a passage with promontories and potholes. Finally, we show that ceiling anastomoses can form by ghost-rock karstification.
The speleothems of trou Noir cave (Gironde, France): the role of their situation in registering climatic signals - The trou Noir is an active cave system (sinkhole-resurgence) situated in the Oligocene porous limestone of the plateau of Entre-deux-Mers near Bordeaux (Gironde). Six stalagmites have been sampled for analyzing the environmental evolution controlled by local parameters inside the cave. The studied indicators are calcitic microfabrics, lamination, discontinuities, porosity, organic matter, and radioactivity. Because of a narrow passage located in the middle of the cave, three speleothems upstream have recorded the fluctuations of the underground river during floods, especially detritic sedimentation (clay/calcite alternations), erosion (internal corrosion surface), mechanical shocks (fissures). Downstream, the three other stalagmites have not been flooded; in the small dry passage near the resurgence, two speleothems show, in thin section, many biologic filaments (bacteria or mycelian filaments) because of organic matter (guano from bats). The site is protected (Natura 2000). The trou Noir is an example of a young cave which has recorded the Holocene evolution, particularly the Little Ice Age (detrital/calcitic stalagmite) and the present period.
