Kalktuff oder Süßwasserkalk oder Quellkalk ist ein poröses, noch junges „sekundäres" Sediment. In Europa kommt es in einigen der Karstgebiete der humiden, gemäßigten Warmklimazone vor, sofern eine Reihe von Bedingungsfaktoren regional vorliegen. Besonders bekannt und untersucht sind Vorkommen der Schwäbischen Alb, der Fränkischen Alb und der Alpenränder.

Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine often has a fibrous or concentric appearance and exists in white, tan, and cream-colored varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material.
Travertine is a terrestrial sedimentary rock, formed by the precipitation of carbonate minerals from solution in ground and surface waters, and/or geothermally heated hot-springs. Similar (but softer and extremely porous) deposits formed from ambient-temperature water are known as tufa.
