Beyond being potentially visually striking features, these structures record processes such as the precipitation of minerals, dissolution, surface processes, and bioturbation.

They can be subdivided into siltstones, mudstones, and claystones based on grain size. The term shale commonly refers to a mudrock that shows fissility. Mudrocks can be described based on grain size, texture, color, mineralogy, fossils, and a variety of other factors. The clay minerals in mudrocks can have physical properties that them economically important.
