Tufa, also known as spring limestone, spring tuff or stream tuff, is a young, porous, secondary sediment. It is a secondary rock because primary limestone sediments from a geological era were re-sedimented after chemical carbonic acid solution weathering and precipitation. In Europe, this type of limestone occurs under favorable conditions in karst areas of the humid, temperate warm climate zone. In Germany, some deposits on and at the edge of the Swabian and Franconian Jura and in the Alpine foothills are particularly well-known and studied.
