Rock description and mineral inventory

Its binder is mainly clay, ferritic and kaolinitic .

use

Obersulzbacher sandstone is well weatherproof. Its weathering behavior depends on the particular rock layer. Only when this sandstone has been exposed to weathering for a long time does it show loosening, sanding and peeling. The upper layer in the quarry is about 4.50 meters thick, so it is possible to extract large-format workpieces. The mined rock is of building block quality. This sandstone was mainly used for solid buildings, bricks, bridges, window and door frames as well as stairs , facades, tombs and in stone carving .

This sandstone was used on the facade of the Horten department store in Baden-Baden , on the Domhotel in Cologne and on the Ingolstadt fortress .
