Oct 02, 2019 Mudstones are fine-grained (silt- to clay-sized grains) unlaminated rocks including siltstones and claystones. Shales have similar grain size, but are laminated. Claystones are composed of clay-sized grains. Most limestones in coal-bearing rocks are fine-grained, but coarse varieties do occasionally occur. Mineral Composition.

Sedimentary Rocks And The Rock Cycle

Grain size is a good indicator of the energy or force required to move a grain of a given size. Large sediments such as gravel, cobbles, and boulders require more energy to move than smaller sand, silt, and clay sized sediments. Grain size is also an indicator of the distance or length of time the sediments may have traveled.
