Mudstone
Mudstone is made up of tiny clay particles (less than 0.05mm) that can’t be seen with the naked eye. 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
