Brick and tile producers in northwestern Germany have always viewed consolidated argillaceous rock from the Carboniferous as a major raw-material base. Large raw material potentials are located in the area of the Ibbenbüren Carboniferous fault block, the Rhenish Slate Mountains and the Thuringian-Franconian-Vogtlandian Slate Mountains. The clay raw materials dating from Rotliegend and Zechstein are of regional importance for the brick and tile industry. This contribution offers information on the respective geneses, stratographic sequences and properties.

1 Global geological history and tectonics

The Carboniferous, also known as the Coal Formation, is the fifth system of the Palaeozoic Era. It began roughly 358.9 million years ago and lasted until about 298.9 years ago. The lower boundary is characterized by an intensive emergence of flora. The upper boundary of the Carboniferous lacks a significant lithostratigraphic reversal. Carboniferous and Permian are therefore referred to as the Carbo-Permian, or Upper Palaeozoic.

In plate-tectonic terms, the Carboniferous is characterized by a progressive coalescence of all land masses to form the...
