The Palaeozoic – new source of raw materials for the clay brick and tile industry (part II)

The Palaeozoic comprises the geological systems Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian: it began around 541 million years ago and ended around 252 million years ago. In the talk, the plate tectonic development is discussed. The speaker will show that the entire geological basement of Germany is built up of large tectonic structures from the Palaeozoic and Permian. Moreover, the complex relationships between diagenesis, early metamorphosis, clay mineral paragenesis and ceramic technology properties will be discussed. Like the first part of the talk, the theory-based observations are rounded off with current examples from the field. Here the focus is on new raw material sources of the Rhenohercynian and Saxothuringian.
