Impact-induced brittle structures have been studied in relation to the Ries impact crater. In 2D and on various scales, the fracture patterns and fragment size distributions are statistically self-similar, i.e. ‘fractal’. Around the impact, four typical fragmentation structures have been identified. Their characteristics and spatial distribution vary systematically with distance to the impact centre. Fragmentation patterns and fragmentation structures are fundamentally different from those generated during quasi-static regional-tectonic deformation. In general, the investigations prove the great advantage of fabric quantifications, specifically using fractal-geometry-based methods.
