Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2Si2O5(OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations 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. They are important constituents of WebClay minerals play a very central role in this co-evolving system. Some 20 years ago, clay scientists looked at clay mineral– microbe studies as a peripheral interest only.
