Mudcracks (also known as mud cracks, desiccation cracks or cracked mud) are sedimentary structures formed as muddy sediment dries and contracts. Crack formation also occurs in clay-bearing soils as a result of a reduction in water content. Fresh mudcracks.Mudcracks form in very fine clay material that has dried out. As the moisture is removed, the surface will split into cracks that extend a short way down into the mud. These cracks form polygons on the surface of the mud.Differential soil moisture content and drying rates influences the soil cracking patterns: parallel arrays of mud crack cells tends to form on an evenly sloped-barren-soil surface …Naturally forming mudcracks start as wet, muddy sediment dries up and contracts. A strain is developed because the top layer shrinks while the material below stays the same size. When this strain becomes large enough, channel cracks form in the dried-up surface to relieve the strain.
