Limestone - an overview | ScienceDirect Topics
Limestone is the most common rock to form karst landscape, but it is not the only rock. Evaporite rocks, composed of the minerals halite, anhydrite, and gypsum, will also dissolve in water to form caves and other karst features. Evaporite caves are present in New Mexico, Texas, and the Black Hills, as well as other areas in the Cordillera.
