One crucial aspect of creating an impact...The resulting contraction cracks act as loci of rapid ground freezing, so that clasts migrate toward and become concentrated in the cracks, forming sorted polygons (Ballantyne and Matthews, 1983). The second, termed ‘primary frost sorting’ by Goldthwait (1976) , proposes that randomly-spaced concentrations of finer sediment freeze more ...When cracks form in a thin contracting layer, they sequentially break the layer into smaller and smaller pieces. A rectilinear crack pattern encodes information about the order of crack formation, as later cracks tend to intersect with earlier cracks at right angles. In a hexagonal pattern, in contrast, the angles between
