So, the type of bedrock and its composition control the rock erosion rate fundamentally. On the other hand, development of porosity in sandstones by dissolution of carbonate cement and calcium carbonate grains causes instability in the rocks and their fragmentation, thus reducing strength of the rocks and their breakdown can result in development of tafoni and honeycombs (THs). So, if these minerals are present in the rocks, they can cause development of specific landforms (such as tafoni and honeycombs (THs)) which are highly affected by chemical processes. For example, calcium carbonate is one of the parameters that are highly affected by chemical reactions. Also chemical processes cause changes in the structure of chemical rocks. Dissolution of chemically unstable grains such as feldspars and carbonates results in development of porosity in the rocks. These controls cause large differences on the earth surface. Lithological controls have the greatest effect on the mechanical behavior of stones and are themselves controlled by factors such as mineral composition, type and amount of cement, matrix, and porosity of sandstones. A wide range of conditions may control the formation and development of tafoni and honeycombs (THs) such as mineralogy. It was observed that in the Mediterranean climate tafoni and honeycombs (THs) are more common and better developed in arid and semiarid climate conditions. Tafoni are the most important geomorphic landforms which were studied in the world. In sandstone landscapes, tafoni and honeycombs (THs) are the most common small-scale weathering forms on near-vertical bare rock surfaces.
