All rocks can be slightly soluble in water, with the result that various karstic landforms can also develop more slowly in the somewhat less soluble magnesium carbonate of dolomite or dolostone, as well as quite quickly in evaporate rocks such as rock salt or gypsum. In fact, some solubility can even occur slowly in silicate rocks such as sandstone, especially where it is cemented with carbonate minerals, or ...
