Cell lime
As Zellenkalk (also travertine , Rauhwacke , Travertine , cells dolomite ) is hole / cellular-porous that have become dolomite or limestone respectively. The porosity is caused by leaching.
Rauwacke (not to be confused with greywacke ) is a rock that originally contained gypsum or anhydrite in addition to dolomite or calcite . During the chemical weathering of the Rauwacke, the gypsum is quickly dissolved and removed with the seepage water. A holey, porous rock remains.
distribution
Cell limestone is a typical rock of the Middle Muschelkalk and Zechstein in Central Europe . In the Alps, for example, it can be found in the Raibler strata of the Northern Limestone Alps . But it is widespread worldwide in comparable rock series, e.g. B. in the north-eastern part of the High Tatras .
