Clays are one of the most common minerals.
Naturally, clays are found in a loose, paste-like or consolidated state. Often they contain many impurities, such as large pebbles, sand, limestone and gypsum inclusions.
In all cases they contain clay minerals, which are microscopically small. It is various combinations of minerals among themselves and other impurities that form various types of clays.
