The Gauinger travertine , also Gauinger limestone called, is in Gauingen in the district of Reutlingen in Baden-Wuerttemberg broken. It is a freshwater limestone , a tufa , in the geological age of the Tertiary : Upper Miocene (Upper Freshwater Molasse ).

Surname

Travertines are clearly layered, solid and polishable. If they are sawn perpendicular to their storage direction, travertines show clear banding . This is not the case with Gauinger Travertine. It is also referred to in the literature as "freshwater limestone in travertine quality". In the natural stone processing trade in Germany, this tufa is called travertine because, in contrast to the tufa, it is firm and can be polished. This trade name has come down historically and therefore has a certain justification.

Rock description and mineral inventory

This natural stone is light brown, heavily patterned and porous. This limestone consists of shell and plant fragments that were encrusted with lime when it was formed. The limestone crusts that coat the fossil remains reach thicknesses in the millimeter to centimeter range. Some of the fragments are several centimeters in size. Freshwater algae are also petrified as algae peloids and peloids . 60 percent of its components are of biological origin, and the percentage of peloids is 40 percent. Some cavities in this travertine are filled with calcite.

Emergence

This limestone was created by deposits of a freshwater lake on the edge of the Swabian Alb (then much further south ) . The lime dissolved in the water coated the dead fauna and flora contained in the lake and formed a layer of rock.

use

The weather resistance of the Gauinger Travertine can be described as good. Outside, its surface is slightly weathered. The result is a loss of polish and the Gauinger travertine bleaches beige. It is frost-resistant and one of the soft rocks . It is relatively easy to edit manually, especially when it is freshly broken . This natural stone is also used in stone carving , for example on the occasion of the Oggelshausen sculpture symposium .

Gauinger travertine is suitable for solid work such as building blocks, floor slabs, stair and floor coverings, facade slabs, monuments and tombs.

Structural use

This limestone was used as a solid stone for the Baroque church in Zwiefalten Monastery , as facade panels at the Galeria Kaufhof in Berlin at Alexanderplatz , Amsterdam Trade Bank, at the Jewish Museum with the Jakobs Synagogue in Munich and at the Schwabenlandhalle in Fellbach .
