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) |

Jahrhundert (n.Chr.) zurück. Es fand ein Abbau im Ausbiß des Alten Lagers statt.
