Mud cracks

Sedimentary structures (cross‑bedding, mud cracks, ripple marks, worm trails and burrows, fossil shells) are not usually visible in hand specimens, but are noticeable in outcrops. Color is not usually significant, because as little as 3% hematite (iron oxide) gives a rich red color. Some pinkish sandstones get their color from feldspar..

Sediments accumulate in a wide variety of environments, both on the continents and in the oceans. Some of the more important of these environments are illustrated in Figure 6.3.1 6.3. 1.

Table 6.4 provides a summary of the processes and ...Cracks that occur before hardening usually are the result of set-tlement within the concrete mass, or shrinkage of the surface (plastic-shrinkage cracks) caused by rapid loss of water while the concrete is still plastic (Fig. 2). Settlement cracks may develop over embedded items, such as reinforcing steel, or adjacent to forms or hardened ...

The mud cracking that was observed post heat treatment is likely due to stresses arising as a result of a volumetric change due to crystallization and potential sintering of the coating at temperature. Ultimately, mud cracking limits the long-term practical use of this coating, especially in terms of environmental protection as cracks …Mud cracks indicate that the sediment was deposited in an area that was alternately wet and dry, whereas ripple marks indicate that the sediment was deposited by directional currents in water or air.
