Summary

[edit]
Description
Deutsch: Aufgelassener Steinbruch von Kalktuff in Gönningen, Schwäbische Alb. Der lokale Fluss Wiesaz produzierte im Holozän mehrere bis zu 15 m hohe Terrassen aus Kalktuff. Der abbauwürdige Teil des Sedimentes ist ausgebeutet, der Terrassenrest wurde renaturiert. Sehr instruktive Reste von Kalktuffbarren wurden in einen „Lehrpfad“ integriert. Der Kalktuff hat vorzügliche Eigenschaften als witterungsbeständiger, gut isolierender Baustoff. Im „bergfeuchten“ Zustand gut bearbeitbar (weich), wurde er in Blöcken und Platten mit Säge und Beil herausgebrochen. Spuren der Steinbruchbearbeitung sind noch gut zu sehen. In der kleinen, alten Stadt Gönningen stehen noch einige Kalktuffbauten.

English: Abandoned quarry of the holocene sediment tufa in Gönningen, Schwäbische Alb. The local river Wiesaz sedimented huge quantities of this sub-type of tufa (“Kalktuff”) in five big terraces. “Kalktuff” is a very frequent material on the Swabian Jura. The material has excellent properties as building material: Easy to form blocks, which are weather resistant and well insulating. The local mineable deposits are exhausted. Yet traces of evidence have been integrated in an “instruction path.
