Mud refers to mud-size carbonate particles, not to mud composed of clay minerals. www.meineke.com locationsam i eligible for federal work study Grain size of a sedimentary rock can be interpreted to indicate several things like the energy of the environment at the time of deposition. The higher the energy (e.g. the swifter the water), the larger the grain size that can be moved.

In general, shale is fissile and readily splits into layers parallel to the bedding plane, which is the plane of clay flake deposition. Shale is laminated, meaning the rock consists of many thin layers that are bound together.A high-energy environment is one in which the water is fast-moving and agitated, able to carry particles of large grain sizes; typically this occurs in shallow lakes & seas and in rivers, as well as deserts. Conversely, a low-energy environment is one in which the water can be very deep and quiet; it can only carry the finest grain sizes (if any!).6.1 Clastic Sedimentary Rocks.
