of the specific patterns of contraction cracks in dried mud, polygonal terrain, columnar joints and eroding gypsum–sand cements. 1. Introduction Cracks in cooling or drying media can form captivating patterns of connected networks, such as the artistic craquelure patterns sometimes seen in pottery glazes toThese particular mud cracks form when wet-dry conditions occur repeatedly, perhaps seasonally. The paper states: We observe exhumed centimetric polygonal ridges with sulfate enrichments, joined at ...The surface of the mud dries a bit, and it sticks together, which creates tension. The tension isn't enough to make the entire surface of the desert shrink apart, so the tension pulls the mud apart, and little tiles form. In order to reduce tension, each point must be close to a crack.
