Kamenitzas or solution pans are closed depressions that develop on rock surfaces in karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant ...
regions formed by dissolution weathering. Usually they form on horizontal, or slightly inclined limestone pavement
A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. The term is mainly used in the UK and Ireland, where many of these landforms have developed dist ...
s where water does not flow but collects into the small depressions. The presence of static water produces small, round, closed pans that are shallow as compared with their depth. Usually they have a diameter of several decimeters, but kamenitzas with a diameter up to 6 m have been documented. Overflow usually creates a solution runnel (karren). This overflow channel often lowers to the extent that it reaches the kamenitza bottom, where further development stops and the pan does not widen any longer. The name kamenitza is of Slavic origin where ''kamen'' means pebble. It came from the wrong hypothesis that small pebbles rotating in a water flow are forming the kamenitzas.
