A new style of sandstone disintegration documented

A recent paper in Geomorphology was also contributed by Michal Filippi of the Institute of Geology. It presents a newly recognized weathering style of sandstone outcrops. Its essence lies in a disconnection of smaller parts of rock along lithological and other discontinuities, which allows the material to dilate and damage the protective bio-crust on the cliff face. This results in a more effective function of erosion factors in the disconnected parts and their accelerated disintegration. As this type of recession of outcrops has also been observed on other granular rocks, it is a phenomenon of a wide significance that deserves further attention.
