Der Untere Buntsandstein ist nicht zu finden. In St. Arnual, am Ostabhang des Sonnenberges bei Saarbrücken, sind diese beiden Altersstufen eindrucksvoll aufgeschlossen. Folgt man den sogenannten Felsenwegen entlang der Saar, so erkennt man das Profil, einschließlich der Violetten Grenzzone, die die Trennung vom Mittleren zum Oberen Buntsandstein darstellt. |

Not negligible for this reason, the idea or the concept of a twin crystal are often associated with a macroscopic building. Modern studies at the nano scale have shown that the formation of twins can occur at a very early stage of crystal growing. Based on these findings, it does beg the request to reconsider the formation mechanisms, and adjacency to the newly different categories. (Text in german) |
