Limestone

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.

What are sedimentary rocks? Shale and limestone

2017-6-26 · By about 3.9 billion years ago (just a little less than four billion years ago), these loose bits of dirt and sand began to clump together again to make new rocks. These were the first sedimentary rocks. Water forms sedimentary rocks. Most sedimentary rock forms in water, where the weight of the water presses down on the layers of sand and clay.The weight squashes them together into a new rock.
