Tufa

Tufa is a type of porous, calcium-rich rock formed when mineral-laden water from springs or rivers deposits calcium carbonate as it cools or evaporates. Over time, these mineral deposits create soft, spongy, and often irregularly shaped formations that can resemble natural sculptures or terraces. Tufa is commonly found in regions with abundant mineral-rich waters, such as hot springs or limestone areas. Its unique and sometimes delicate appearance makes it notable in geological and ecological contexts, serving as habitats for diverse plant and animal species in some environments.
