Karst - Wikipedia, the free encyclopedia
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite,[1] but also in gypsum.[2] It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions.[3]
