Bunte Breccia, Nördlinger RiesYour model is disabled. For more details go to Edit properties3D Model
The Bunte Breccia foramtion extents radially from the Nörlinger Ries crater by some 45 km. The vast majority (i.e., >90%) of the deposits outside the crater rim are Bunte Breccia. This makes it volumetrically the largest geologic formation produced by the impact. Bunte Breccia formation is covered by the well-known Suevites. These melt-bearing breccias consist of shocked, lithic or melted rock fragments, some of which are sources from the crystalline basement (granite, gneiss, amphibolite). In contrast to the suevites, the Bunte Breccia are a low-shock level ejecta and experiences temperatures <100°C and pressures less than 10 GPa and do not contain any melts.
