Clay minerals Wikipedia

Clay minerals are hydrous aluminium phyllosilies, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other ions found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.
