Ries Impact Structure (Nördlingen)
Organizer: Claudia Trepmann, Stefan Hölzl, Sandra Piazolo
Estimated fee: 40 €
Date: June 11
Number of participants: 15 max.
The 26 km-diameter Ries crater developed from a meteorite impact within the Swabian-Franconian Alb, Germany, about 15 Ma ago (for a recent review article see Stöffler et al., 2013). The Ries is the type locality of “suevite”, which is a characteristic impact breccia and prominent building stone (e.g., St. Georg church, Nördlingen and early 19th century building at cross section of Kochstraße and Friedrichstraße, Berlin, Germany). The proximal and distal impact rocks of the mid-sized complex crater with sedimentary and crystalline target rocks are well preserved. We will visit one of the most impressive outcrops of the suevite, the Aumühle, and further outcrops that provide insight into the dramatic and manifold geological processes triggered by the impact.
