What is another word for calcrete?
Pronunciation: [kˈalkɹiːt] (IPA) 
Calcrete is a sedimentary rock that is formed by the precipitation of calcium carbonate in soils and sediments. It is normally found in arid or semi-arid areas and is characterized by its light color, hardness, and angular shape. Other terms used to describe calcrete include duricrust, hardpan, and caliche. Duricrust refers to a hard layer of rock-like material that forms over soil and is composed of cemented fragments. Hardpan, on the other hand, refers to a compacted layer of soil that is nearly impenetrable. Caliche is a similar term to calcrete, but is typically used to refer to surface deposits of calcium carbonate rather than rock formations.
