Halloysite is a 1:1 aluminosilicate clay mineral with the empirical formula Al2Si2O5(OH)4. Its main constituents are aluminium, silicon and hydrogen. Halloysite typically forms by hydrothermal alteration of alumino-silicate minerals. It can occur intermixed with dickite, kaolinite, montmorillonite and other clay minerals. X-ray diffraction studies are required for positive identification. It was first described in 1826 and named after the Belgian geologist Omalius d'Halloy.
