Geology
The „Horst Peter-Stollen“ gypsum-anhydrite mine is located in a geological unit known as the „Trier-Bitburg Triassic Trough“. The Triassic deposits (approx. 253 to 202 million years ago) in this area in turn belonged to the large unit of the Germanic Basin. The „Trier-Bitburg Triassic Trough“ can be localised between the „Rhenish Massif“ and the „Brabant Massif“.
The geological section through the „Trier-Bitburg Triassic Trough“ shows the exact location of the mine and the most important geological elements. The gypsum deposit is located in rocks of the Muschelkalk (exactly mm1; Muschelkalk: 246 - 239 million years ago).
The deposit being mined has a thickness of approx. 10 metres. Gypsum is a so-called precipitation rock. Seawater is concentrated in a lagoon, for example, through evaporation, so that the constituents accumulate. If the concentration exceeds a certain value, gypsum (CaSO4 * 2 H2O). In the further course of diagenesis, the water is expelled and anhydrite (CaSO4), so to speak „anhydrous gypsum“. At a later point in time, the anhydrite can partially or completely transform back into gypsum under suitable environmental conditions.
