Riedöschinger travertine

from Wikipedia, the free encyclopedia
General view of the red stone

The Riedöschinger travertine , also sometimes referred to as red stone , is a travertine limestone deposit in an open quarry near the village of Riedöschingen ( Schwarzwald-Baar district , Baden-Württemberg , Germany ) in the municipality of the city of Blumberg at around 780 meters above sea level.

Travertine as a name

Travertines ( Latin: lapis tiburtinus ) have a number of special characteristics (e.g. genetic characteristics), which give this rock its own category in addition to limestone tuffs, sea limestone and sintering . The type locality of travertine is the travertine of Tivoli near Rome . The so-called Roman travertine has been mined as a building block since ancient times and can be seen, for example, on St. Peter's Square in Rome.

Like some rock formations in Yellowstone National Park , the Riedöschinger travertine originated from hot water deposits . The emergence of the Riedöschinger travertine is presumably closely related to the formation of the volcanoes in Hegau . Carbonated and thermal water is said to have risen from a crevice and was enriched with dissolved lime during its ascent through the Jura . When it reaches the surface of the earth, the water has collected in a trough and the lime is then excreted.

Rock description

Red travertines are relatively rare. The so-called red stone has alternating red, purple and white shades depending on the storage of iron oxides . The reddish color can be traced back to the iron oxides contained in the basement and swept along with it . From the horizontal storage it can also be concluded that the Rote Stein is located directly at this former source area.

In addition to the geology of this travertine, the numerous fossils that occur are also of interest. Various frog - and Lurcharten talked at times the activity of the sources in this area and the crystallization were included in the resulting rock over.


There are few proven examples of use of this natural stone. It was used as a brick when building houses in the vicinity of Riedöschingen and in the chancel in the Church of St. Martin in Riedöschingen as steps and flooring.


The travertine quarry is located about 1.3 km west of Riedöschingen. The 20 meter high quarry wall of the rock layer can be viewed in the quarry and traced 150 meters in the north with decreasing thickness . The total extent of this rock layer is not known. The quarry has not been in operation since 1995.

Rock deposits in the area

Another example of thermal sintered limestone (travertine) is located northeast of Tengen on the top of the Wannenberg. The Blue Stone of Randen, a basalt that is considered to be the westernmost foothills of the Hegau, is also on the municipality of Blumberg .
