Summary

[edit]
Description
Deutsch: Die Kalktuffnase ist Teil des mächtigen Kalktuffvorkommens der Gütersteiner Wasserfalls, Schwäbische Alb, nahe Bad Urach. Zwischen den Moospflänzchen wird der in den Gesteinsschichten der Alb gelöste Kalk beim Herabrieseln wieder ausgefällt und umkrustet allmählich die weiter wachsenden Moose.

Mehrere Karstquellen entspringen als Schichtquellen des „Seichten Karsts“ aus dem Hang, der sich unterhalb der steilen Traufkante befindet. Traufkante, Wald und Quellspalten befinden sich noch im Naturschutzgebiet Rutschen. Die Quellen treten aus dem Mittleren Weißjura-Mergel zur Unteren Felsenkalk-Formation (ki1 und ki2) aus.
Unmittelbar unterhalb der Quellen entstand im frühen Holozän, als Sediment, eine große Terrasse aus rezentem Kalktuff. Am Rand dieser „Hochwiese“ entstand die Kalktuffnase. Um 1300 enstand hier ein Kloster, welches zuletzt zum Orden der Kartäuser gehörte, bis die Gebäude ca. um 1550 im Zuge der Reformation abetragen wurden.

Die imposanten Kalktuffmengen bei der „Ehemaligen Kartause Güterstein“ können mit dem gleichen Sedimentphänomen des Uracher Wasserfalls in Zusammenhang gebracht werden. Die jahreszeitlich schwankenden Wassermengen haben in den Kalktuffablagerungen am Hang zu üppiger Vegetation geführt.

English: Calcareous tuff is a sediment, which precipitates chemically from freshwater at ambient temperature. The sediment may cover moss, that continues to grow or it may become a sludgy mass, in which leaves, small branches and other debris are deposited. When dry, the sediment is quite hard, but porous, lightweight and durable. The material was ideal building material before the invention of concrete.
The karst springs emerge from rock walls of the „Albtrauf“ (escarpment of the Swabian Alb) near Bad Urach and flow onto a large terrace. There the calcium carbonate precipitates over fresh moss and produces a continually growing bulge, before the water drips down a steep slope. On the slope more calcium carbonate is precipitated and a rich vegetation develops amongst the sediment. The location is called “Gütersteiner Wasserfall”.
