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 ripple mark is a wavelike sculpture on water covered sand surfaces obtained by wave action [16].?
Dating by accelerator mass spectrometry of wooden artifacts, cord, and charcoal samples from Guitarrero Cave, Peru, supports the antiquity of South America's earliest textiles and other perishable remains. The new dates are consistent with those obtained from disintegration counters and leave little doubt about the integrity of the lower Preceramic layers and their early cultivars. Reevaluation of the mode of deposition suggests that most of the remains resulted from short-term use of the cave in the eighth millennium B.C., with a possible brief human visit as early as 12,560 years ago
The decay of cosmic ray-induced 26Al and 10Be in quartz sediments allows the calculation of sediment emplacement ages back to about five million years. Two examples are given: Mammoth Cave (Kentucky) and Atapuerca Cave (Spain). The sediments in the Mammoth Cave System were an integral part of how the cave was formed. The sediments reveal the evolution of the cave system, and how cave development is tightly coupled to river incision and aggradation. In this case, Mammoth Cave was ideal because it was a water-table cave that carried quartz from local bedrock. In contrast, Atapuerca is a sedimentary infill where sediment (and animals) fell into a preexisting cavity. Such cave infills are the norm in archaeology and paleoanthropology because they collect bones and artifacts over long periods of time. In this case, the cosmogenic nuclides dated the sedimentary infill rather than the cave itself.
