Abstract

Throughout the world, large caves in rocks (tafoni) are found, which originate from salt weathering. The growth of tafoni has been studied with a model that describes how a rock surface, containing a small pit, disintegrates by salt crystallization during wetting/drying cycles. In the model the rock is mapped on a grid. The migration and crystallization of salts are simulated explicitly in the drying phase of a cycle. At the end of each wetting/drying cycle the amount of salt deposits at the grid nodes is evaluated and the shape of the rock surface is adjusted by removing nodes. Discussion of the results
