Mudstone depositional environment
These tiny particles are deposited in quiet low-energy environments like tidal flats, lakes, and the deep sea. When mudstone is buried beneath many layers of sediment deposited on top, it may be compressed to form shale, which breaks easily into thin flakes. Uses of Mudstone Mudstone consists of a variety of types, and this heterogeneity is outlined in Boulesteix et al. (2020); principally by mudstone that is derived from a turbidity current or sediment gravity flow (deposited via suspension); that of remobilized mudstone (sediment gravity flow or mass movement) ( Walker and Massingill, 1970 ); and that of a hemipel...Packstones indicate a range of depositional properties. Mud suggests lower-energy processes, whereas the abundance of grains suggests higher-energy processes.

The carbonates represent ..."High-Energy" and "Low-Energy" Depositional Environments. Flowing water is the dominant natural force causing erosion and deposition on Earth. The faster the water moves, the higher the energy in a physical setting. As flowing water increases in speed, the more it may become turbulent, increasing its ability to lift and move particles.Five recurring mudstone bedset types (A–E) record sand and mud transport and depositional processes across the OCC depositional profile. Those bedset types are defined based upon mudstone grading, fabric and characteristics of subordinate sandstone beds and lenses, and are internally composed of at least two but often more than two lithofacies.A thick succession of siltstone and mudstone can be found in the middle to upper parts of this member, which represented the shallow lacustrine facies during the flooding period of the early HST. ...
