General description

This category includes very diverse landmarks which have one thing in common: all of them are created by springs which are depositing chemical sediments – silica, carbonates, salt or other chemical compounds.

Tufa, travertine or sinter?

In scientific literature there are very different terms which describe this phenomenon. Usage of these terms is not universally accepted and there is some confusion regarding their usage. Some of most popular terms are listed below:


Calcareous (lime) and porous deposits formed by waterbodies with ambient temperature, for most part – springs.

Spring water often contains dissolved lime. When the water reaches surface and air, lime is precipitated: right at the mouth of spring or after some distance. Such sediments are porous, light and are called tufa. It is popular construction stone – when it is mined, it can be easily formed and cut but over the time it becomes hard.

Tufa formations are very diverse and often – amazing and beautiful. Many times tufa is deposited along the waterfalls of the streams formed by springs. Such waterfalls sometimes are very high – Anisakan Falls in Burma have a total height of approximately 320 m, all lined with tufa.

Tufa often forms natural barrages – natural dams, turning the spring-fed rivers into a chain of small lakes, divided by tufa dams and linked by waterfalls falling over these dams. Such tufa dams have formed such amazing monuments of nature as Plitvice Lakes (Croatia) or Semuc Champey (Guatemala).

Amazing type of tufa formations is tufa walls – wall shaped tufa formations with spring stream floving on top of these natural "aqueducts". Amazing example is Usterling Wachsender Felsen in Germany, Bavaria.

Tufa serves as great media for plant growth and often tufa formations are covered with beautiful moss cover and other plants. Amazing example is Dard Springs (France).

If lime deposits are created by thermal springs or if deposits are slowly created in media without much life (e.g. in caves), lime is much denser. Such dense sediments of lime are called travertine. In fact, word “travertine” often is referred also to cold (ambient) water formations and the border between terms "tufa" and "travertine" is not firmly set.

Travertine formations often are beautiful and form such world-class landmarks as travertine terraces, e.g. Pamukkale (Turkey) or Huanglong (China). Similar to tufa, also travertine forms natural barrages, there are many travertine waterfalls with hot water flowing over it.


Any deposits which have been naturally fused together by heat or pressure (without melting them), can be called sinters.

Springs can not create such conditions – both carbonates and silicates need higher temperatures and pressure for sintering than hot springs can provide. Nevertheless the hard porous silicate or (sometimes) carbonate sediments of hot springs are called sinters.

Terraces, rimstone pools and gours

Some of the most amazing formations which can be created by springs are natural terraces consisting of numerous rimstone pools (sometimes called also gours). These natural formations occur in cases when mineral-rich spring water spreads in thin layer and flows down the slope. Soon the deposits form small ridges, water falls over these ridges and exactly on the rim of these ridges the sedimentation is faster than elsewhere – these rims rise upwards. Thus over the time form natural terraces consisting from numerous smaller lakes – rimstone pools. In order to form clean, large and beautiful terraces, there is needed constant flow of mineral rich water and little impact from elsewhere, e.g. plant growth, impact of human and animal feet. Impressive rimstone pools form in caves (here they often are called gours)- the most impressive could be the giant gours in Khoun Xe cave, Laos.

There are beautiful examples of rimstone pools above the ground too. Millions of tourists visit the beautiful Pamukkale (Turkey), Mammoth Hot Springs (United States) or Huanglong (China). Less known are the beautiful and unique Dallol salt springs (Ethiopia) or the unbelievable Rabbitkettle Tufa Mound (Canada) and some other sites.

Karst Hydrogeology and Geomorphology

Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated.


During the spring of 1960, an uncle showed me a ‘petrifying spring’ near Plaxtol in Kent Dwhere twigs had been encased in a calcareous jacket. It became apparent that here was a wealth of information about a rock whose formation was so rapid, that the process could be studied in days rather than years – an exceptional state of affairs. A search of the literature also revealed that the rock, a form of travertine, had other unusual features.
