Occurrence

During the Cretaceous Period 130 to 65 million years ago, sands were transported into the North Sudetian Basin by water and wind , which sedimented layer by layer. Silica-containing solutions flowed into the pore space. Silica and overlying sediments solidified the sands into sandstone. The younger sediments weathered and exposed the sandstone deposits near the surface.

Rock description

It is a fine-grained sandstone of yellow, yellow-brown and yellow-white color. Its feldspar and mica content is very low. The rock is not very stratified and is characterized by a small pore space.

The rock partly shows yellow-rusty colors. There are also iron pebbles and quartz veins that run through the sandstone at an oblique angle to the stratification level.

use

Today the Warthauer sandstone is used for restorations and new buildings, in the new building sector in particular for facade cladding, floor coverings, cover plates and stone . It is also used for sculpting work. This natural stone is frost-resistant.

This sandstone was used on the Reichstag building , the Berlin Cathedral and the Kaiser Wilhelm Memorial Church in Berlin, the New Palais and Sanssouci Palace in Potsdam , the Central Theater in Dresden , the Dresdner Bank Berlin , the Berlin University of the Arts , the University of Breslau and the Mercedes branch. Benz in Moscow .
