Ground-penetrating radar (GPR) of the Ries crater's ejecta blanket at Aumühle

Abstract: Different formation models have been proposed for the emplacement of the Bunte breccia in the Ries crater. One possible mechanism includes rampart formation similar to the formation of Martian rampart craters, which typically show a characteristic thickening (rampart) and thinning (moat) of the inner and outer ejecta deposits and radially oriented grooves and ridges (“striations”).
For characterizing the lateral extend of the undulated contact plane between Bunte breccia and suevite, we carried out a geophysical survey in 2019 for the surrounding area of the Aumühle quarry. In addition, we conducted a photogrammetric drone mapping for the entire quarry and its surrounding.
In the GPR and ERT profiles, the Aumühle quarry shows an undulating and sharp contact between Bunte breccia and suevite whose relief amplitude is in the order of 5-10 m. The striations are a few meters wide and several meters deep
