Summary[edit]
DescriptionVaalser Grünsand (Geusenweg, Dachsbau).jpg |
Deutsch: Sehr wahrscheinlich war es ein Dachs, der hier am sogenannten Geusenweg im Südwesten von Aachen Sande freigelegt hat. Große Teile des Vaalserbergs und des Preuswaldes im Südwesten von Aachen sind aus den sogenannten Vaalser Grünsanden[1] aufgebaut. Der Name besteht Professor Walter zurecht, da die Sand im frischen Aufschluss durch das eisenhaltige Mineral Glaukonit tatsächlich grünlich sein können. Diesen Farbeindruck machten die Sande hier im Bild aber nicht. Sie zeigten keine Spur einer grünen Färbung. Die Gründsande wurden in der geologischen Zeit der Oberkreide abgelagert, als Aachen an einer flachen Küsten eines tropischen Meeres lag. Professor Walter, von der RWTH Aachen, beschrieb in seinem Buch über Aachener Georouten[2] die Grünsande entlang des Geusenweges. Die Stelle befindet sich am Geusenweg. Überquert man die Fußbrücke über die Bahnlinie nach Gemmenich von Westen her kommend, dann liegt die Fundstelle etwa 100 Schritte jenseits der Bahnstrecke, leicht hangaufwärts. Eine weiterer Aufschluss befindet sich in vielleicht anderthalb Kilometern Entfernung am Nordhang des Friedrichwaldes. Folgt man von der Fundstelle aus der Georoute von Professor Walter in Richtung Westen, so kommt man zum Türmchen Beeck, wo in der Nähe mehrere Tertiärquarzite liegen. |
