Porous limestone rock formed when carbonate minerals precipitate out of ambient temperature water
This article is about the calcareous rock. For the volcanic rock also called "tufa", see
Tuff.
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine or thermogene travertine. Tufa is sometimes referred to as meteogene travertine.[1]
