Aug 9, 2023 · The rover spotted the mud cracks in 2021 as it explored a rock target nicknamed “Pontours,” found within a transitional zone between a clay-rich layer and one higher up that is enriched with salty minerals called sulfates.

Sedimentary structures: unidirectional cross-beds, asymmetric ripples in channel; mudcracks, raindrop impressions on floodplain; Fossils: coastal plants (i.e. marsh grasses) and roots, marine fish, shells; Other notes: coarser sediment in the channel, finer grained material in the floodplain, large foreset (incline beds) at outcrop scale .

Learn more.mudcracks can be preserved in sedimentary rocks. These structures provide important information about depositional environments such as flow direction, climate (arid, semi-arid, or humid) and setting (e.g. fluvial, lacustrine, or marine). These structures also may indicate which direction was originally up within the rock. Tectonic forces can fold and overturn …Mudcracks form when a shallow body of water (e.g., a tidal flat or pond or even a puddle), into which muddy sediments have been deposited, dries up and cracks. This happens because the clay in the upper mud layer tends to shrink on drying, and so it cracks because it occupies less space when it is dry. Mudcracks are common in tidal flats and shallow lake environments, and indicate the drying of a previously wet, fine-grained sediment. Stacks of beds with mudcracks indicate repeated wetting and drying of the local environment. Figure 15. Mudcracks on drying lake bed, TX Figure 16. Mudcracks in a mudstone, Watahomigi Fm. EXERCISES 11.Mudcracks (also known as mud cracks, desiccation cracks or cracked mud) are sedimentary structures formed as muddy sediment dries and contracts.
