Desiccation cracking
WebJan 21, 2024 · Desiccation cracks are a common component of continental deposits on Earth (Figure 3a), whereas they have been reported on Mars from the Murray Formation and Meridiani Planum . Martian desiccation cracks meet orthogonally, forming T-junctions [ 14 ]; this compares favourably with the T-junction observed in a pair of stick-like structures … 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.
